By fitting solar to your home, you can reduce your electricity bills forever, protecting yourself from increasing energy prices, reduce your impact on the environment and receive a Feed-in-Tariff income for the electricity generated which provides an attractive return on your initial investment.
Solar systems generate electricity in proportion to the amount of sunlight received, so un-shaded, preferably south facing areas are best - the roofs of many houses are ideal!
As a guide, a 4kWp system covering 26 sq. m can supply approximately 3200 kWh (units) of electricity in a typical year - almost all of the average annual electricity consumption for a household of four and would cost £6000 - £8000.
All generation is during hours of daylight and most in summer, least in winter. Best use is obtained when electricity consumption runs in parallel to electricity generation. For example: appliances such as washing machines or dishwashers, which do not have to operate at a certain time can be operated when the solar system is supplying plenty of power.
