In this increasingly environmentally Power Efficiency Guide aware and money conscious world more and more people are choosing to use solar power systems in their homes. A solar powered house uses less electricity and is better for the environment. But many people are worried about how much it costs. This article will tell you how to install solar panels onto your home so you can save money in the future. Electricity from a light source is called photovoltaic. This solar power system converts sunlight into electricity that can be used to run common household items like lights appliances and computers. A solar photovoltaic PV system enables you to generate electricity from the sunlight which is an inexhaustible resource that costs you nothing. PV systems do not need fuel do not cause pollution and can last for as many as 25 years with very little maintenance. Over its lifetime a PV system located on the roof of your house could save about 34 tons of greenhouse gasses. The amount of electricity produced by a PV cell depends on the strength of the light which it received. For that reason PV cells usually produce more solar electricity when it is sunny than they do on overcast days. This doesnt mean that the solar system can not function when it is cloudy outside. Recently PV technology has been used in the roofs and walls of houses businesses and factories in city areas.
