Solar PV panels (photovoltaics)
Solar PV panels require only daylight, not necessarily sunlight, and are therefore capable of generating electricity on a cloudy day. They can be installed on the roof of most homes that can support the equipment and can easily be connected to a buildings electricity supply. The stronger the sunshine the more electricity is produced.
PV Cells come in a variety of shapes and colours, from grey “solar tiles” that look like roof tiles to panels and transparent cells that you can use on conservatories and glass.
Benefits of Solar PV panels
Reduce your carbon footprint
When in use, a Solar PV panel does not generate greenhouse gases or cause pollution. Each killowatt-peak (kWp) of electricity produced can save approximately 455 kilograms of carbon dioxide emissions compared with electricity generated from fossil fuels.
Reduce your electricity bills
Sunlight is free, so once you pay for the initial installation, your electricity costs will be greatly reduced. A typical home PV system can produce about 40% of electricity a household uses in an year.
Sell electricity back to the grid
If your system is producing more electricity than you need, or when you can’t use it someone else can – and you can sell it back to the grid.
Store electricity for a cloudy day
If your home isn’t connected to the national grid you can store excess electricity in batteries to use when you need it
