How To Maintain Your Solar Panels And Get The Most Out Of Your Servicing Appointment

Solar panels are relatively simple to look after. There are no moving parts, for example, which makes them less likely to succumb to an engineering fault. If they are looked after properly, they should remain problem-free for many years. However, like all systems of this kind, it is a good idea to arrange regular servicing appointments to make sure that any issues are spotted and fixed sooner, rather than later. It is advised to book a servicing appointment at least once every five years, or more often if you prefer.

Get installation advice from your servicing appointment

Much can be done to protect your solar power system when it is first installed. Make sure the panels are fitted correctly and securely so they don’t slip or break. While they obviously need to be positioned in a location that catches plenty of sunshine, take care not to put them anywhere that could be overly exposed to storms, winds and bad weather. Set the right angle to help any snow slide off, rather than collect on the surface and cause damage over time.

Always choose a professional installation company that will take time to ensure the perfect fit and talk you through how to care for the panels correctly. If a servicing package is offered as part of the installation price, or an option is given to include this on ongoing aftercare, take it, as this can represent better value for money than going elsewhere.

Check for issues on your solar panels yourself

Don’t wait until your servicing appointment to take a look at your panels yourself to make sure nothing is going wrong. While you are not likely to want to scale the house to inspect the panels close up, you can still look at them from the ground to see if there is anything glaringly wrong. Use a pair of binoculars to check for an excess build-up of dirt or debris, cracks, slipped panels or loose fittings or bolts.

Pay attention to how the system is performing too. Is the amount of electricity being generated reducing, or is it taking longer to fill up the storage battery than before? Keep an eye on your metre readings to see if there are any issues arising with the electricity supply. This could signal that there is a problem with the panels themselves, or the wiring and internal connection systems. Always check performance at the same time of day to give a better idea of how well your system is working over the longer term.

Remove the risks to your solar panels

Where possible, remove anything that could cause damage to your solar panels, such as overhanging branches. These could not only break off and fall onto the system in high winds, but they are also a great place for birds to perch and release acidic poo down onto the panels. Leafy trees could also be causing more shade to fall onto the surfaces where the panels are installed than you would like – this can compromise their ability to capture energy from the sun’s rays.

Any climbing plants, such as ivy, vines or creepers, which look like they are going to encroach onto the panels should also be pruned back or removed altogether before they cause damage further up. This can also help keep gutters free from foliage to improve your drainage system and protect roof tiles not covered by photovoltaic panels or their mountings.

Things to tell your servicing engineer

When your servicing appointment is drawing near, take another close look at your system. Make some notes about what to tell your engineer when they arrive to carry out the work. For example, take down some details about how the electricity performance has been recently. If there is an instance of bad weather and it is safe to do so, go outside to see how the panels are coping with the adverse conditions. Let the engineer know of any concerns you may have around your system’s ongoing durability or state of wear and tear.

Check that the inverters are still flashing green, which tells you that all is working correctly. If they are not, note this and tell your engineer on their arrival. Point out any areas which are particularly dirty and may need more attention. Finally, set aside some funds to pay for any repairs that might be necessary. The longer you leave repairs to a solar panel system, the costlier the issue will be to put right when you eventually sign up for the work.

Solar panels in remote and rural households - solar panels on the roof of a rural house near a forest

Installing Solar Panels In Remote And Rural Households

Many of the big electricity companies opt to invest more heavily in more densely populated areas. Therefore, some of the more remote villages and rural communities do not always receive such comprehensive coverage or services from them. One solution for homeowners living in remote areas is to install solar panels in remote and rural households. This enables them to capture energy from the sun and convert it into electricity for their own use. It lessens their reliance on the National Grid for power and supports those wishing to live more sustainably.

Sustainability also makes solar panels highly attractive for people seeking to live as ‘off-grid’ as possible. Often, such households will be drawn to remote areas and rural living. Being able to have solar panels installed on the roof or a flat surface can help ensure a steady flow of electricity to provide lighting, heating and power on a day-to-day basis. Adding a storage battery to the solar power set-up can also allow any electricity not used straight away to be stored and used when the sun is not providing enough energy for the photovoltaic cells to work, such as at night.

Here are some more reasons why remote communities and rural households interested in living off-grid should consider investing in solar panels…

Solar panels in remote and rural households provide power anytime, anywhere

Formerly the preserve of larger homes, solar panel technology has become increasingly diverse, meaning that smaller dwellings can now take advantage of the versatile technology too. The ability to sell back surplus electricity that a smaller rural household doesn’t use can also help boost the coffers and provide an additional income stream. Solar panel systems needn’t spoil the look of a countryside home either – the panels themselves come in discreet, attractive designs and can be fitted to a roof or flat surface in the best way to reduce the visual impact. 

Solar panels still work on rural households on a cloudy day

There doesn’t have to always be bright sunshine for solar panels to power a home in a remote location effectively – they can work on cloudy days too. Storage battery solutions also enable solar power to be stored in readiness for powering the property at night. This provides homeowners with an excellent ROI – being able to generate their own electricity will, over time, reduce power bills and pay back money spent on the initial installation of the solar panels.

Solar power protects against power outages

Another way in which solar panels can benefit rural households is that they provide protection against power cuts and interruptions caused by problems with the National Grid.  When power cuts happen, rural areas often take the brunt of the resulting chaos, since towns and cities are normally prioritised when it comes to restoring power and fixing damage. Knowing that remote properties can still access the electricity being produced by a solar panel system can be extremely reassuring.

Solar panels free up funds

There is often a correlation between rural households and higher levels of domestic poverty. Managing to reduce energy bills and possibly even sell unused electricity back to the National Grid might be able to assist with balancing the books in the longer term.

Clearly, installing the system in the first place will represent a financial outlay, but there may be help available in the form of grants or loans to help pay for this – check out your local council in the first instance to see if there is anything suitable. Plus, as photovoltaic technology advances, the costs will fall and the efficacy of the system increase, helping free up rural households funds even more.

Easy to look after

Finally, solar panel maintenance overall is not complex, as solar panels tend to be robust and easy to care for. The photovoltaic cells that capture the solar energy are normally encased in tempered glass and strengthened by steel frames. Additionally, the converters and other technology required to generate electricity are also very well insulated and protected against damage, general wear and tear and adverse weather conditions.

This also helps keep repair and upgrading costs down for rural and remote households. However, that said, investing in annual or other maintenance contracts for solar panels and associated technology can offer peace of mind and help spot potential problems early before they cause more serious disruption.

Solar Panels In Winter: Coping With A Cold Snap

Once again, the British weather is top of the UK news agenda. January 2023 is seeing plummeting temperatures, as well as plenty of frost, ice and snow across many parts of the country. So, talking about solar panels in winter of year may not seem like the most obvious course of action. However, when the cold weather descends, it is important to think about how it might affect solar panels exposed on rooftops in sub-zero temperatures. Also, solar panels don’t stop working in the winter. There are still many ways in which the electricity generated can power people’s homes and businesses, as well as reduce fuel bills and contribute to sustainable living goals.

Solar power in winter weather

It is a common misconception that solar panels need strong rays from the sun to operate. In fact, they can still generate electricity when the sun is weaker or partially obscured by clouds. They also carry on working even when temperatures drop below zero. The only thing that could affect their efficacy in a big way would be if heavy snowfalls on the roof completely cover the panels, blocking their contact with the sun. In that case, efforts to remove the snow – but only if it is safe to do so – could help them return to normal service. When installing solar panels in winter, bear in mind that snow can melt and slide off those placed at an angle far quicker than from totally flat layouts.

The good news, however, is that solar panels can work well in wintry conditions. They can even be more efficient in colder temperatures than at the height of summer. This is because overly hot conditions can prevent them from working and affect the electronics they contain. Also, the photovoltaic cells rely on direct contact from sunlight – the stronger the better. The heat that comes from the sun does not come into the equation. Dull, overcast days with less sunlight breaking through the clouds, therefore, are less helpful than those crisp, frozen winter days when the sun is shining brightly, with its rays reflecting back onto the panels from the frosty, white rooftops around them.

Caring for photovoltaic panel systems

As with any investment of this nature in your home or business, taking care of solar panels in winter correctly will help prolong their working life. It will also improve their efficacy in producing electricity at a time of year when additional light and heat is usually required. As well as adjusting the angle of your solar panels to allow snow to slide off more quickly, this action can also help capture more sunlight as it sits lower in the sky on shorter winter days. Placing the panels at a steeper incline could help compensate for this change in the sun’s position.

Other tips around caring for solar panels in winter include using the right tools to clear snow, ice or frost from their surfaces. Always take great care when attempting maintenance of this nature, as frosty surfaces can make outdoor work like this more treacherous. If you do decide to tackle it, use a soft-bristled snow brush, rather than a rake or hard-bristled broom. This helps avoid scratching and damaging the panels. If the snow is stubborn and will not come off easily, don’t scrub too hard – it will melt eventually and the panels can then resume their service.

Don’t forget to protect your batteries as well during winter. They can be affected by cold weather just as much as other parts of the solar power system. Insulate them against plunging temperatures by wrapping them well if they are outdoors or, if possible, repositioning them inside the property. Watch their discharge levels closely, as you will, most likely, need more electricity than usual on colder, gloomier days.

Finally, book your solar panel and battery servicing appointment now. It is easy to forget in the frenzy of a busy working or domestic life. There may be more appointments available during the winter, so you won’t have to wait quite so long for an engineer to arrive. Likewise, if you don’t have solar panels installed, or are interested in an upgrade or replacement system, take advantage of the quieter winter months to book an initial consultation.

Why you Should Add Solar Panels to Your New Build Property Plans

The benefits of solar power for domestic properties are well known. From reduced energy bills to a more sustainable way of living, switching wholly or partially to renewable energy can reap homeowners many rewards. So, what if you are planning a new build property project and are considering what type of power to install? All of these advantages still apply. Plus, there are several other benefits that can help your new build to meet regulations, increase resale value and ensure its sustainability credentials from day one.

Here are some key reasons why new builds and solar panels can make a great match.

  • Improve SAP calculations

Recent changes in Part L of the Building Regulations and Standard Assessment Procedures (SAP) have meant that renewable energy measures such as solar panels are increasingly sought-after for new-build homes. All new homes are now required by law to include enough energy saving measures to pass the SAP calculation score and become as energy self-sufficient as possible. SAP calculations go from 1 to 100 and indicate the annual cost of energy associated with the property, as well as its overall environmental performance. Factors include heating, lighting and overall structure. While the SAP calculation system has been in place since 1995, the changes to the regulation now means that properties must secure a ‘pass’ score, with a minimum of 10% of consumed electricity on site now required to be self-generated.

  • Enhance the property’s BREEAM score

Another assessment system for new builds is the BREEA score (Building Research Establishment Environmental Assessment). This scheme was established in 1990 and calculates the sustainability rating of a building. It helps construction companies rate the sustainability of their work and to reduce the negative effects that construction processes have on the environment. Having solar panel included on a new build can help increase the BREEAM score and thus add even more to the property’s proven green credentials and sustainability factor.

  • Lower installation costs, now and in the future 

It stands to reason that, having solar panels incorporated into the roof from the beginning means that the roof will require fewer tiles and, potentially, lower labour costs. The photovoltaic panels sit flush with the roof and are larger than single tiles. As a result, they will not be as time-consuming to place in the correct position and line up with the rest of the surface. Additionally, if the solar panels are already installed before the first resident moves in, they will no need to have a solar energy system added later on, and neither will their future buyers. The infrastructure needed to live more sustainably when it comes to generating electricity will already be up and working.

  • Reduce overall carbon footprint

Increasingly, people seeking to buy a house, new build or otherwise, are becoming concerned with the carbon footprint that the property will generate. Stringent targets set by the UK to reach Net Zero by 2030 are driving increased interest in energy saving measures like solar panels. Many people are keen to do their bit to contribute to this worthy cause and help fight the effects of climate change. Having solar panels already in place will be an attractive addition and powerful marketing message for any new build company wishing to show their commitment to the green agenda. Adding storage batteries to allow homeowners to store excess electricity and use it at night or on duller days is another incentive well worth considering.

  • Encourage wider use of renewable energy

Finally, the more new-build properties that are constructed with solar panels firmly in place, the quicker the idea will spread to other homeowners and property professionals in the area. As with any desirable feature on a building, having solar panels not only up and running from the start can help to add value to the property and hence its surrounding neighbourhood. They will also look far more attractive if they can be installed flush against the roof, rather than added later and resting on tiles. If your new-build property can lead the way in starting a trend locally for switching to renewable energy and a greener lifestyle, this can only be a good thing for both your property and its neighbouring buildings and community.

5 Advantages of Installing Flat Roof Solar Panels

When you think of solar panels, we’re betting you conjure up images of a sloping roof with panels fixed on firmly to capture the sun’s energy at an optimum angle. However, the system can work just as effectively on flat roofs as they do on slopping ones. Depending on the type and size of the system you choose, flat roof solar panels can actually work more effectively than some sloping ones. So, whether you are interested in flat roof solar panels for a domestic property or commercial premises, read on to find out the advantages of flat roof solar panels and why they are such a great investment.

Why Choose Flat Roof Solar Panels?

In some cases, the choice of which type of solar panels to invest in is made for you – if you only have space for them on a sloped or flat roof, for example. However, if you do have some flexibility, it is well worth looking into flat roof solar panels. Here are the advantages of flat roof solar panels and why they can be a winning solution.

1. Versatility in How They Are Installed

When you fit solar panels to a sloping roof, you need to work with the existing angle and pitch of the roof. This is not the case for flat roof panel installations. As there is no pitch, the system can be angled as you choose, in order to capture the most sun and work as efficiently as possible. A good angle for solar panels is somewhere between 30 and 60 degrees.

UPS Solar Commercial Solar Panels - advantages of flat roof solar panels

Panels can go in the middle of the flat roof or to either side with no obstacles in their way. Installers use specially designed brackets to fit the flat roof solar panels securely and then angle them exactly as they need to. If there are concerns over whether they will withstand heavy weather conditions, metal frames or ballast can be added for extra support and weight.

2. Self-Cleaning and Safer Maintenance

One concern that many people have about installing solar roof panels is how they can keep them clean and free from damage and general wear and tear. The UK sees a lot of rain, which helps the panels to ‘self-clean’ as the water runs down them. This is still possible on flat roof solar panels, as they can be angled slightly to allow the rain to do its work. Maintenance and repairs can often be easier on flat roofs too, as there is generally enough space around the panels for someone to stand safely for as long as they need when checking and working on the panels.

3. Better Looking Configurations

Solar panels can be hard to hide on a sloping roof, as they will stand out visually from many angles. When installing them on a flat roof, however, the angle can be adjusted so it is less intrusive to the surrounding views. They are more discreet from street level and do not require homeowners to remove attractive tiles or terracotta embellishments from a sloping roof. Flat roofs tend to be fairly practical and simple in design, making the addition of a flat roof solar panel less of an intrusion. In fact, some modern, industrial flat roof designs can positively benefit from having stylish flat roof solar panels installed on top of them.

4. More Wind-Proof

We have already mentioned how the rain can still help keep flat roof solar panels clean if they are angled up enough to allow the water to run down them. Conversely, however, the wind can be far less useful to solar panel systems, especially if they are fitted to sloping rooftops that are too tall to withstand high winds without sustaining damage. Choosing your own angle for a flat roof can enable you to adjust the slant to account for high winds and keep the system safer and less prone to storm damage.

5. Easy Access to Green, Renewable Energy

Flat roof solar panels are just as effective as sloped roof configurations in providing renewable, sustainable electricity direct from the sun’s rays. They are made up of the same type of photovoltaic cells, which capture the solar energy before the system converts it into useable electricity for the home or workplace. An additional battery for solar power storage can also be connected to the system so that any surplus electricity that is not used right away can be stored and used later. For example, when the sun’s rays are absent at night, or weaker or obscured during a cloudy or dull day.

How Many Types of Solar Panels Do You Know About?

Solar panels have become a common sight on rooftops and flat surfaces across the UK. More and more homes and commercial buildings are benefitting from access to renewable energy from the sun to light, heat and power essential appliances. The working technology of all types of solar panels is straightforward. Photovoltaic cells embedded in solar panels capture energy directly from the sun’s rays and convert it into useable electricity

The electricity can either be used immediately or stored in special batteries for use later on when the sun is not as strong or during the night. However, there are many different types of solar panels to choose from, which makes switching to renewable energy more versatile than ever before.

Panels and their pros (and cons)

The great thing about having different types of solar panels is that you can choose the most effective, convenient and affordable configuration for your individual circumstances. Here are four of the most popular types of solar panels to compare their advantages and disadvantages.

1. Standard solar panels

This type of solar panel is arguably the most recognisable and popular option on sale today. They are sturdy and easy to install and can be positioned to capture as much of the sun’s energy as possible. This accuracy results in higher yields of energy, making returns on the initial investment possible much earlier on. Normally made up of silicon wafers, each panel contains several rows of photovoltaic cells that do the actual conversion work. Monocrystalline cells appear black, while polycrystalline ones have a blue tone, due to how the light interacts with their surfaces.

types of solar panels - standard solar panels

A sheet of glass goes on the top of each panel and the whole unit is framed to add extra rigidity and strength. Pros include easy availability and installation, effective efficient energy conversion and affordable prices. Cons include the fact that other, more modern technology is available for households or businesses looking for the latest innovations in renewable energy.

2. Thin-film solar panels

This lighter option is slowly capturing more and more of the market as people look for less obtrusive ways to generate solar power in their businesses or homes. They are extremely versatile, as they can be manufactured in foldable and roll-up formats. This allows them to be fitted more closely to the contours of an existing roof or flat surface. They can also be fitted to a caravan or mobile home for solar power generation on the move.

types of solar panels

However, they are less efficient than standard solar panels, so they may need to cover a wider surface area to generate the same amount of electricity. They also require more complex disposal at the end of their working life, due to the toxic cadmium telluride that is often contained within the film.

3. Solar tiles

Solar tiles offer the huge advantage of being more aesthetically pleasing than other types of solar panels. They can be interlocked and replace standard roof tiles, rather than being placed on top of them. They can be a more discreet option, and work well on an existing roof, as well as provide an excellent alternative energy course for a new build.

Are Solar Tiles a Good Investment

However, solar tiles are not always as efficient as some of the more traditional solar panel types and can therefore take longer to recoup initial costs via electricity bill reductions. Installation can be costlier too, given the newer technology and more complex interlocking tile layout.

4. Tempered or plate glass solar panels

The type of glass or covering used in solar panels is an extremely important consideration when placing an order. Due to the exposed position of solar panels, they must be able to withstand harsh weather conditions and fluctuating temperatures. Tempered or plate glass adds valuable protection against the elements and adds an extra layer over the delicate photovoltaic cell technology that makes the solar panels work in the first place.

Advantages include longevity for the whole solar power system, as well as improved aesthetics and fewer repairs. Disadvantages exist around the increased price point and heavier weight involved. As with all types of solar panels, those with added tempered or plate glass on top must be fitted by a professional installer. This will ensure maximum efficiency and prevent the risk of the panels getting damaged, slipping off the roof or breaking.

Large Scale Solar: Decarbonising the Global Energy Sector with Solar Power

What Does it Mean to Decarbonise?

Simply put, decarbonisation is the reduction of carbon – zero-carbon. We live in a time where the world is in dire need of economic change, and one of the ways to do that is through minimising our reliance on fossil fuels and making a radical switch to clean energy sources. The long-term goal is to become a climate-resilient, zero-carbon global economy.  Among the many methods to support this, large scale solar power is one of them.

Why Do We Need to Decarbonise?

A major cause of cumulative CO₂ emissions is burning fossil fuels for energy. We know by now that this has led to an increased output of greenhouse gases and, over time, resulted in global warming. The rise in CO₂ output from human activity has negatively impacted our global economy and, in efforts to save our future, nations around the world have pledged to make greener choices to meet global temperature standards set by the Paris Agreement. 

The Intergovernmental Panel on Climate Change (IPCC) has declared that a move to a complete carbon-zero network of the energy sector by 2050 is non-negotiable to meet the target of capping global temperature rise at 1.5°C. 

How Do We Achieve Low-Carbon?

Since the announcement of the climate emergency, there has been the worldwide implementation of renewable energy like wind, solar and nuclear power and bioenergy. Decarbonised electricity can be used for the same uses as fossil fuels, for example, boilers for building heating. 

The UK has the ambition to be powered by affordable, clean energy by 2035. Plans include deploying a new generation of home-grown green technologies, including solar – which remains the third-largest renewable energy technology. 

What is Solar Power?

Solar power is the energy ‘captured’ from the sun that is used to generate electricity. As more and more people strive to become energy-efficient and reduce their energy costs, solar has become a widespread option. Its increase in affordability and ease of use has made it a popular choice amongst UK households. What’s more, depending on your energy supplier, you can even receive payments for extra energy you generate. 

Large scale solar power

How do Solar Panels Work?

Solar panels convert sunlight into electrical energy through photovoltaic (PV) panels. When light shines on the semi-conductive material, a direct current of electricity is created and passes through the system to eventually get usable energy to electrify your home. The PV panels react to visible light – so as long as it’s light enough to see, the panel can generate electricity. 

Rooftop solar can create thermal energy that can be used to provide heat in your home from water heating and air heating and essentially supply households with decentralized heating. With the use of storage batteries, unused energy can be stored and used at a later time. 

How is Solar Energy Used Globally?

Solar thermal energy for heating water and air in households and buildings is only one of the uses of this alternative energy source. There is growing ambition that utility-scale solar will be used for end-use electrification (e.g. vehicles, transport, water heating, etc) and production of clean fuels, like hydrogen. 

The US and China are top traders in the solar market and the US has plans to transition to a zero-carbon electric grid by 2050. This type of green technology has been adopted worldwide and is deployed for small and large-scale uses.

Advantages of Large Scale Solar Power

1. Renewable

As mentioned earlier, solar panels generate electricity from visible light. Since there is daytime light in all four corners of the earth, solar power can work. However, the more sunshine there is, the more electricity will be generated – making this a great renewable option for sunnier climates. There is also the added fact that sunlight is an inexhaustible source of energy, and can be used without much consequence for future generations. 

The carbon footprint is relatively small as no pollutants are released into the air. Higher demand for solar power worldwide means a reduction in the dependence on foreign oil and fossil fuels. Also, the materials usually used – silicon sheets – are recyclable, making solar power a clean alternative energy source.

2. Money-saving

The more power your solar panels would generate, the less electricity you would have to buy from the grid, therefore making this cheaper in the long run. Additionally, solar power in the UK is being financially incentivised, as households can receive payments for extra electricity generated. 

3. Low maintenance

Solar panels don’t contain any loose or moving parts, so require minimal maintenance. Since the panels are usually placed at an angle on houses and buildings, rainfall slides right down them. Dirt and debris may block the panels and require you to remove them but other than that, it’s a self-sufficient system. Solar panels also have a life span of about 20-25 years, with little loss in efficiency. 

4. Efficient

When transmitting energy from power stations to homes and public buildings, there is unavoidable energy loss through heating the power lines. Less energy is wasted when using the sun to produce heat or electricity, as the power comes directly from the panel connected to your building. 

5. Land-use

Large scale solar parks can co-exist amongst farm animals grazing on land – this is called agrivoltaic. The simultaneous use of land benefits landowners, the environment, and animals. The photovoltaic panels can also be removed without harm to the ground.

Large scale solar can also appear as floating solar (solar panels on water) doesn’t require any land space and so can be a viable option for smaller countries. 

6. Rise in ‘green’ careers

With the continuing demand for solar, there will be a proportionate rise in demand for solar power transportation and installation jobs. An example of this large scale solar power is in India, where a 250 MW concentrated solar power (CSP) project has become a source of local jobs.  

Demand for large scale solar power

Challenges in Decarbonising the Energy Sector

Sustainable development has its challenges – socially, economically and ecologically. Energy transition needs to be compatible with social aspects (household costs) as well as environmental sustainability (protecting land and climate) and economic needs (security of energy supply and prices). 

  • Levelised cost of energy (LCOE)

Capital costs of large scale solar deployment run high in comparison to competing fuel sources. 

Moreover, ongoing maintenance costs of solar power plants may be steep, along with refinancing the loans used to build them.

  • Weather-dependent

One of the main obstacles to solar power becoming a reliable green energy source is the varying intensities of solar radiation in different areas of the world. Nations on the equator receive the highest amount of solar energy, as do those with drier climates. 

Most residential panels have around a 20% efficiency rate, and anything more than that will be substantially more expensive. The more efficient the panels, the more expensive it is to make. 

  • Land space

Large areas of land are required for macro-scale solar farms. The biggest solar grids are built in large open spaces such as deserts, so countries with less landmass, or have to compromise agricultural land, will be disadvantaged. 

  • Environmental impacts

The manufacturing of solar panels can result in harmful compounds, such as nitrogen trifluoride. This by-product is a highly toxic greenhouse gas, much more insidious than carbon dioxide. But as solar technology gains more accessibility and demand, manufacturers may be able to steer clear of dangerous substances.  

On a global scale, large scale solar power seems to be a very valuable option – according to the three pillars of sustainability (social, economic, ecological). On reviewing the arguments, the advantages seem to outweigh the challenges in the long term. The trend of falling prices for solar power will make the transition to a solar-powered, carbon-free global economy highly achievable.

Benefits of Insulated Solar Roof Panels

As the technology behind solar energy grows more sophisticated, the possibilities about what it can achieve are increasing. Insulated Solar Roof Panels are a popular choice for solar power as they are straightforward to install on most roof shapes and sizes. They work by harnessing the sun’s energy and converting it into electricity. This electricity is then used to heat and power the home or commercial premises. On the other hand, Solar thermal panels capture solar energy that goes directly to generating hot water for the property. However, some types of solar thermal systems can offer additional benefits too. Thermal insulated solar roof panels can add a crucial heat retention layer to the property.

Four Key Questions About Solar Thermal Panels

Solar thermal and insulated solar roof panels can help reduce heating costs when rising fuel bills are top of the UK news agenda. It is worth working out how the initial in-roof solar panels UK cost can be offset against the savings you can achieve on mains electricity. For an idea of the average solar thermal system and roof-integrated solar panels UK cost, speak to an expert at UPS Solar. In the meantime, here are four questions about insulated solar thermal panels.

SHARP 300w Solar Panels - Insulated Solar Roof Panels

1. How Do Solar Panels Insulate Your Roof?

The primary way that solar technology can add insulation is by installing in-roof panels. These are not the same as standard photovoltaic solar panels that sit on top of the existing roof. Insulated solar in-roof panels do precisely what their name suggests. They are fitted into the roof, replacing some tiles and lying flat against the adjoining ones. This removes gaps between tiles where draughts can get inside the property. The evacuated tube collectors of solar thermal panels are also designed with vacuum insulation capabilities to reduce heat loss further. Householders living in listed buildings may need planning permission to fit solar thermal panels and insulated in-roof solar panel systems.

2. Does Solar Thermal Power Work in the Winter?

Solar thermal technologies are a highly effective way to produce hot water. The technology has been around for a while – longer than more modern solar PV panels – yet it can be far more efficient, capturing more energy and converting it into heat for water more quickly. The process can still be used to ensure hot water during the winter, although the solar energy output will be lower on dull days than during sunnier periods.

Benefits of Insulated Solar Roof Panels

You may need to supplement it with more conventional methods of heating water on especially overcast winter days. However, the solar thermal power produced will still help keep energy bills lower in the long run. It is advisable to check on your solar thermal power in-roof panels during heavy snow. This is because the system’s insulating properties will prevent any heat from escaping to melt away the settled snow. So, you may need to remove it manually to ensure the system is running as efficiently as possible.

3. Can Solar Panels Make a House Cooler?

Conversely, installing solar thermal panels can also help keep a house cool in the summer. The multiple layers of an in-roof solar thermal system promote airflow between each one. While this offers insulation during colder periods, the air can also cool the panel down when temperatures are higher and, subsequently, the roof beneath it. This can make a difference to temperatures inside the house during hotter weather. Not having to have a gas boiler or mains electric heating system switched on so high to ensure hot water for bathing, cooking, cleaning, etc., can also help reduce the overall heat level in the house on a summer’s day.

Benefits of Insulated Solar Roof Panels

4. Which is more efficient: solar thermal or PV?

PV technology converts solar power into usable electricity, whereas solar thermal systems provide hot water. Solar thermal panels installed on a roof comprise thermal flat plates or evacuated tubes collectors that use the sun’s energy to produce hot water. This is then passed through pipes and stored in the property’s hot water cylinder for use when required. Solar temperatures hitting the collectors can reach up to 90 degrees C, making the system highly effective and quick. Solar thermal panels’ price differences will depend on the size and type of solar thermal system.

Photovoltaic panels are also effective in converting solar energy into electricity. However, this is used or stored for general use, including heating and power. You can also use electricity from PV panels to charge an electric vehicle. Installation is also easier than solar thermal panels. However, the initial price of the system can be higher. Both systems could make the householder eligible for renewable heat incentive (RHI) payment schemes. In terms of which is more efficient, both offer advantages. The final choice of system will depend entirely on what you plan to use solar energy for – general heating, powering and charging, or simply hot water.

What You Need to Know About Government Solar Panel Schemes

One advantage to switching to renewable energy solutions such as solar panels has been the possibility of receiving financial support from Government Solar Panel Schemes. Incentives have regularly offered grants, vouchers and discounts off the costs of turning away from fossil fuels and towards renewable heat and electricity. Although the scheme names and details change occasionally, there is usually something to help with initial installation costs for things like solar panels, heat pumps and solar battery systems.

Keeping up with the latest solar panel grants

Take the time to look out for updates to energy saving and energy efficiency support schemes that are out there. Some offer discounts for solar panel installation, while others pay you for excess electricity exported back to the National Grid. One Government deal sees a five per cent VAT reduction on the cost of either solar panels or their installation for people over sixty years old or in receipt of income or disability benefits.

Whatever type of green deal or ‘rent your roof’ arrangement you can find, you will likely find ways to reduce energy bills and enjoy better energy efficiency at the same time. Other deals and incentive schemes are also out there to help people meet the costs of switching to renewable energy. Here are some more details about three key green deals currently available for homes in the UK.

What You Need to Know About Government Solar Panel Schemes

1. Smart Export Guarantee (SEG)

Many people who have already installed solar panel systems will be familiar with the Feed-in Tariff (FIT) scheme that began in 2010. The project encouraged people to switch to solar power by incentivising them to return any excess electricity that they generated back to the National Grid in return for a payment. The FIT scheme closed to new applicants in April 2019. It has since been replaced by a reasonably similar Smart Export Guarantee (SEG) scheme in January 2020.

This new process also allows people to sell surplus electricity back to the National Grid. However, it places the onus on electricity suppliers to offer their customers suitable tariffs to ensure that the scheme compensates them adequately. Energy suppliers with more than 150,000 customers are obliged to take part.

There are two types of SEG tariffs available to people who have installed solar panels under the arrangements. A fixed rate keeps the price the same throughout the duration of the contract. On the other hand, a variable rate enables the energy supplier to change the amount they pay you for the electricity you generate after an initial period of notice. Exact amounts will depend on where you live and how much electricity you use yourself.

UPS Solar Panels

To qualify for the scheme, you must have an approved renewable energy technology installed (including solar PV panels) with the required capacity and industry approvals. You cannot be a part of any other FIT schemes and must have an SEG-compatible smart meter installed to record the energy you export accurately.

2. Green Homes Grant Scheme

While solar PV panels are currently not part of the Green Homes Grant Scheme, you can apply for a grant to put towards a solar thermal panel system in England. This uses the solar energy from the sun to generate hot water for a property. As of September 2020, qualifying applicants have been able to get up to two-thirds of thermal solar panel installation costs on their property. Some grants are worth up to £5,000, while others aimed at low-income families could yield as much as £10,000 to cover installation costs. These grants are available until 31 March 2022.

UPS Solar Residential Solar Panels - Government Solar Panel Schemes

Both homeowners and landlords can apply for a Green Homes Grant voucher. It can be granted alongside other funding from Energy Company Obligation (ECO) schemes so long as both funding sets are used for different energy efficiency measures. For example, solar thermal panels plus loft insulation or cavity wall insulation. A Green Homes Grant can also be applied alongside the domestic renewable heat incentive (RHI) scheme.

3. Renewable Heat Incentive (RHI)

Again, this deal is currently only available for people installing solar thermal panels – not photovoltaic solar power systems. It offers qualifying people seven years of quarterly cash payments in return for their switching to renewable heating methods. The deal is due to end on 31 March 2022. So, anyone interested in registering who has not already done so now will need to act swiftly to take advantage. The RHI scheme was initially meant for commercial premises to heat their water using solar power. It was extended to domestic properties in 2014.

As well as solar thermal panels, RHI funding extends to other green heating methods for water, such as biomass boilers and pellet stoves. The seven-year support scheme offers payments tied to the type of technology used and the latest related tariffs.

Get Ahead of Rising Fuel Bills and Convert Electricity on the Move With Flexible Solar Panels

Rising energy costs have been a top news agenda item for several weeks now. Families and businesses across the UK are bracing themselves for increases in their fuel bills. People are tightening their belts around other expenditures in anticipation. For many, reduced spending power for holidays and foreign trips results in greater interest in taking trips away in leisure vehicles and marine craft instead. This is where flexible solar panels can become something of a game-changer. Not only do they allow travellers to generate their own power on the move, but they can also reduce a household’s reliance on the National Grid and help mitigate against the large fuel bills that are predicted to arrive in the Spring.

The technology behind solar photovoltaic panels has become increasingly sophisticated to the extent that several different types and configurations of solar panels exist, including flexible solar panels designed to generate electricity on the move. These versatile, portable panels are the ideal answer for people looking for ways to live more sustainably while using their boat, motorhome, caravan or campervan.

Flexible Solar Panels

Why should you opt for flexible solar panels?

Flexible solar panels offer a lightweight, convenient way to generate electricity and move towards a more sustainable way to provide power away from home. Other benefits include the following:

· They are designed to be light with a wafer-thin backing to prevent excess weight compromising a leisure vehicle’s performance.

· The flexible solar panels bend to fit the shape of the roof or flat surface on which they are installed.

· The panels can be unrolled and tied to a yacht or boat’s boom to harness the sun’s energy while out on the water.

· Thanks to the technology used, the panels can work in low light conditions as well as direct, bright sunshine.

· Additionally, flexible solar panels are made from tough, durable materials that can withstand difficult weather conditions and many miles on the open road or water.

· Best of all, they offer excellent efficiency to produce optimum amounts of power.

Customisation options also include folding designs for more accessible transportation and accessorising extension cables, battery chargers, and storage for protection en route. They are straightforward to install. However, there is plenty of advice and support available to ensure that they work in the way that you need them to, wherever you are at the time. For example, they can be rolled for easy transportation by bicycle or kayak. This is made possible by the amorphous technologies used to construct the panels instead of the more rigid, crystalline method that most standard solar panels employ.

On average, a smaller flexible solar panel will provide electricity to keep your leisure vehicle, or marine craft lit and your phones and devices charged. Larger versions offer a greater energy output, enabling the powering of microwaves, kettles, hairdryers and fridges. All essential things make a trip away from home more luxurious and fun.

Meanwhile, the biggest flexible solar panel configurations offer the capacity to live off-grid for longer. This can make more extreme travelling, such as wild camping, more of a possibility for the modern adventure-seeker. As energy prices continue to rise, the option could become more and more attractive to people looking to control what they spend on heat, light and power.

Other uses for flexible solar panels

Of course, flexible solar panels can also be used in the main home or commercial premises. They can be a temporary energy generating solution while permanent panels are ordered and installed. Their flexibility enables them to be installed in places where larger, rigid alternatives are unable to fit, such as non-standard rooftops, sheds and outhouses. While they don’t always last as long as rigid panels, they still offer a reasonable length of useful life and generate good results in producing electricity.

The self-cleaning, easy maintenance makes flexible solar panels convenient for almost any location and situation. They also provide a great introduction to solar power for families interested in switching to renewable energy and a more sustainable lifestyle but want to test the waters with a smaller system first. Yet, despite their smaller size, the panels can still offer high performance with effective solar energy harnessing and converting into usable electricity. Often, the panels are installed simply by peeling off the backing sheet and sticking them in place using the adhesive already included on the reverse side.
