How solar electric works

Solar panels on your roof convert sunlight directly into DC electricity. Panels work best in bright sunlight, but still produce electricity on cloudy days.
The generated electricity is converted to a standard AC supply, using an inverter. The inverter can be in your loft space or in the garage near to the consumer unit.
A generation meter measures all of the electricity that is produced. Under the Feed In Tariff scheme, you are paid for every unit, whether you use it or not.
The solar electricity is either used by your household appliances, or if not required it is exported to the National Grid.
Any solar electricity used in the house is FREE and reduces the amount that you have to buy from your electricity supplier. So the readings on your existing import meter will be lower, giving additional savings.
