A solar power system is a financial investment that will reduce your cost of living. It provides a portion of your power requirements with no running cost. Electricity costs are rising every year so the more power you can produce at no cost the better off you are financially. When your usage is low and your system is generating excess power you are a micro power station as you will be selling your unused power back to your power company. Installing a solar power system adds more value to your home than the system should cost. This is confirmed in studies by real estate groups and is becoming a key selling point when homes are advertised for sale.
