Solar Panels

Generating renewable electricity

How solar panels work

Solar panels, also known as photovoltaics (PV), harness the sun’s energy and generate renewable electricity.

Solar PV systems are made up of several panels, with each panel generating around 355W of energy in strong sunlight. The cells do not necessarily require direct sunlight to produce energy and operate even when it is overcast during the day. However, if there is intense sunshine then more electricity will be generated.

A typical system may contain around 10 panels – these generate Direct Current (DC). Because your household appliances use Alternating Current (AC), an inverter is also installed to convert DC to AC. This electricity can be used throughout your home or exported to the grid.

Key benefits of Solar Panels

  • Cut your electricity bills; sunlight is free, so once you’ve paid for the initial installation your electricity costs will be reduced.
  • Cut your carbon footprint; solar electricity is low-carbon, renewable energy. A typical home solar PV system could save around one tonne of carbon per year, depending on where you live in the UK.
  • Reduce your electricity use during daylight hours; you’ll be generating electricity even on cloudy days, but if you’re using more power around your home than your panels are generating, or during the evening when your panels are not generating any electricity, you’ll be supplementing this by importing electricity from the grid.
  • Ideal for large properties with South facing roof space.

Why should I install Solar Panels?

As your solar PV system will be working at its peak during daylight hours, it’s a good idea to run your electrical appliances such as your washing machine, dishwasher, and iron during the day. 

You can combine solar PV with other renewable technologies such as heat pumps or solar hot water systems. These technologies work well with each other, as solar PV could help power a heat pump, for example, or several of these systems could feed into a thermal store.

Combine your Solar panels with home battery storage and you can save considerably on your electricity costs because of the flexibility afforded. Your battery system can also take electricity from the grid when it is at its cheapest and use it during peak periods in the evening (where costs can be high), creating the best possible balance between solar and grid electricity with the lowest possible costs.
