The term solar power is used to describe a number of methods of harnessing energy from the light of the Sun. It has been present in many traditional building methods for centuries, but has become of increasing interest in developed countries as the environmental costs and limited supply of other power sources such as fossil fuels are realized. Solar Power is a clean, green energy solution which can help save money on your energy bill and avoid the environmental impact of fossil fuel power stations, such as greenhouse gas emissions and local air pollution. It is already in widespread use where other power supplies are absent, such as in remote locations and in space. I just want to tell you about PV (photo voltaic). The demand for electricity is higher every day, but the sources are running out – solar energy can help to solve this problem. Photovoltaic or solar cells (a few different types) as they are often called, are semiconductor devices that convert sunlight into direct current (DC) electricity. Groups of PV cells are electrically configured into modules and arrays, which can be used to charge batteries, operate motors, and to power any number of electrical loads. With the appropriate power conversion equipment, PV systems can produce alternating current (AC) compatible with any conventional appliances, and can operate in parallel with, and interconnected to, the utility grid. So, if you are building new house, think about installing solar cells and help the earth to give a chance to next generations.
