How do solar panels work?

  • Solar panels need sunlight to be able to generate electricity. Winters in the UK seem long and dark, so it’s understandable to think solar panels won’t work in the winter. In fact, they work better in cooler temperatures. Learn more about the efficiency of solar panels in the winter.
  • You can pair your solar panels with a battery to store the energy you don’t use, and either use it later or sell it back to the grid. Learn more about how solar batteries store energy and why they’re an amazing addition to your solar installation.
  • The output of a solar panel depends on various factors, like positioning, sun exposure, environmental factors and more. Yet on average, a single solar panel produces 250 to 430 watts per hour. Find out more about what impacts the amount of energy solar panels generate.

The different types of solar panels

  • There are a few types of solar panels that can be used to generate electricity, and each type can be used for distinct purposes. In the UK, monocrystalline and polycrystalline solar panels are usually the most popular.
  • The number of solar panels you’ll need to be installed at home will depend on several factors. We tailor your solar package to suit the specifications and requirements of your home to ensure you get the most out of your investment.

Installing and maintaining solar panels

  • When you’re wondering how many solar panels we’ll need to install on your roof, we’re here to help. It depends on several factors, but this guide should give you a better idea of the number of solar panels you’ll need.
  • The angle and direction solar panels are installed will determine their efficiency. Find out more about the correct solar panel roof placement, including important considerations if you have a flat roof.

  • There are a few grants and schemes for solar panels that you might be able to get when installing a solar panel system. Please bear in mind that these were accurate at the time of publishing.

Are solar panels worth it?

  • It’s common to wonder if solar is worth the investment. We believe solar panels are worth the upfront costs, even in the UK. Installing solar panels and a storage system can help you become more energy-independent and save on your bills. We’re on a mission to help people in Great Britain live more sustainably and lower their bills, and solar is a great way to do that.
