Solar is a great way to reduce your energy bills and your reliance on energy companies by harnessing free renewable energy from the sun. In the majority of cases, solar will save you money in two key ways. It will help to reduce your electricity bill by reducing the amount of power you need to purchase from the grid. Secondly through the feed in tariff you receive for selling back the excess power you make. The exact amount depends on many factors including the size of the system, the location of your system, local electricity rates and your average energy consumption and your usage patterns.
