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 income for any surplus electricity exported to the grid.
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 3800 kWh (units) of electricity in a typical year - almost all of the average annual electricity consumption for a household of four and would cost £3000 - £5000.
Adding battery storage will help you store your excess generation (that would normally be exported) for use later when your consumption is higher than your generation. As electricity prices rise this sort of battery storage system will become more and more cost effective. Some systems can also provide back-up power during power cuts.
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 water heating, washing machines, dishwashers, or charging electric vehicles which do not have to operate at a certain time can be operated when the solar system is supplying plenty of power.
