Costs for installing a solar electricity system vary a lot - an average system costs between £8,000 and £20,000, depending on its size and type.
In general the more electricity the system can generate, the more it costs but the more it could save.
Savings can be considerable - almost 1 tonne of CO2 a year, and around £200 off your electricity bill*. A 2 kWp system could provide around 40% of a household's yearly electricity needs.
Maintenance is generally small - you'll need to keep the panels relatively clean and make sure trees don't begin to overshadow them.
