Our guide to solar panels and some common questions we’re asked.

Here’s a guide to how solar panels work in the UK. We have also provided some common questions and answers we get asked. 

How do solar panels work?

Solar panels work by converting sunlight into electricity. When sunlight hits the panels, it excites electrons in the silicon cells within the panels, creating an electrical current. This current is then used to power electrical devices or stored for later use.

This process happens without any moving parts and produces no emissions, making solar PV panels a clean and sustainable source of energy.

Solar Panels – true or false

We address some of the common solar panel misconceptions. Check out our FAQs for more. 

They don't work in UK weather - FALSE

Solar panels don’t rely on direct sunlight, they rely on daylight. They work fine in the UK, as we have plenty of daytime sunlight. 

If you don't use it, you lose it - TRUE

You must use the electricity at the time of generation or store this with a battery. Otherwise, the energy will be fed back to the grid, but you will be paid for this as part of the Smart Export Guarantee.

They're expensive to maintain - FALSE

Solar panels do not require any regular maintenance work. They are self cleaning and self sufficient. 

Solar Panels – important information

The UK home solar panel industry has been clouded with scandal. Previously, unreliable installers were installing panels on long term leases, meaning the customers had to provide 50%  of their feed in tariff payments to the company. The householder was tied in to these contracts and companies had registered charges on the property. This made it difficult for people to sell their home. 

In another mis-selling scandal, householders had to get a loan for the installation and were told that their feed in tariff payments would offset the loan repayments. This was often not the case. 

The ECO4 scheme is different, you will own the panels outright from day 1 and there won’t  be any charges on your property.

Solar Panel FAQs

  • Does it need to be sunny for solar panels to work?

    Solar panels work well in a range of different conditions. Modern solar panels are reliant on daylight rather than direct sunlight to work, so they work perfectly fine in the majority of places.

  • Will I own the solar panels myself or will you take ownership of my roof?

    This isn’t a roof rental scheme. You will own the solar panels in full, outright, from day one. The full costs are completely covered by the ECO4 scheme. You won’t have to pay and you won’t have to give away any ownership of your roof or have any rental agreements. You won’t have any problems selling your house and there won’t be any charges placed on your property.

  • What if my roof is unsuitable?

    If the roof on your home is unsuitable, you can get ground-mounted solar panels.

  • Do I need to clean my solar panels?

    Modern solar panels are self-cleaning. Thanks to the beautiful British weather, any debris or dirt is removed with regular rainfall.

  • How long do solar panels last?

    Manufacturers typically provide a 25 year warranty with solar panels. After this time, performance tends to reduce, but they do still work well. Solar panels can last for over 40 years.

  • Can the solar panels be recycled?

    Over 90% of modern solar panel components can currently be recycled. With a typical life-span of 40 years, we feel that there will be additional recycling options available once your solar panels reach their end of life.

  • Do my solar panels need to be maintained?

    You don’t need to carry out any regular maintenance on your solar panels. It is important to monitor the surrounding area to detect any shade from trees that may grow over time.

  • What happens to the electricity I don’t use?

    If you don’t use the electricity at the point of generation, you can either store this energy in a battery, or you can sell this back to the grid as part of the Smart Export Guarantee.
