Cut your carbon footprint: solar electricity is green, renewables energy and doesn't release any harmful carbon dioxide or other pollutants. A typical home PV system could save around 1200 kg of carbon dioxide per year - that's around 30 tonnes over its lifetime.
Cut your electricity bills: sunlight is free, so once you've paid for the initial installation your electricity costs will be greatly reduced. A typical home PV system can produce around 40% of the electricity a household uses in a 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 use it - and you could make a bit of money. Read more about selling electricity.
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.
