Some utilities have net metering programs, which further enhance the economics of PV. Net metering means that when your PV system generates more power than you need, the excess goes to the utility grid and the meter runs backward. This allows you to receive full retail value for the power that your PV system generates. Solar rebates and government incentives reduce the cost of solar systems. The size of your system determine price for PV system. Those prices depend of numerous of factors: manufacturer, retailer, installer, PV efficiency, place of mounting panels, batteries, net metering…Low is - small PV systems cost more dollars per watt then bigger PV system. Prices go down fast and best way to inform about them is to visit PV provider’s web site. How much dollars you will save depends of many factors: is electricity expensive in your area, is there a lot of sun during year, what amount of your electricity needs you intend to replace with solar energy? If your utility offers net metering, you and your utility will pay the same price for each other’s electricity. Discuss these issues with your potential PV provider and request a written estimate of the average annual energy production from the PV system and price for that system. Search for more offers and compare them.Cost of electricity constantly go up, cost of solar systems constantly go down and governments constantly increase financial support for using renewable energy. So decision is easy. For example, a 2-kW, at a average US residential energy rate 2009. of $0.12/kWh will save about $456 per year:
