Solar powered electricity generation is one of the best things that have happened to the environment. This is an alternative form of energy production that does not emit any hazardous material into the environment and uses something that is naturally available as its source.

Photovoltaic energy is the conversion of sunlight to electricity through a photovoltaic cell (PV), a non-mechanical device usually made from silicon alloys. As sunlight strikes a PV cell, it creates an electron imbalance between the front and back surfaces of the cell.

This (PV) solar cells are thin silicon disks that convert sunlight into electricity. These disks act as energy sources for a wide variety of uses, including: calculators and other small devices telecommunications, rooftop panels on individual houses; and for lighting, pumping, and medical refrigeration for villages in developing countries. Photovoltaic modules are usually rigid, rectangular devices ranging in size from 2’ by 4’ to as large as 4’ by 8’. Some PV module technologies are flexible and as large as 2’ by about 20’ or even larger.

Generally photovoltaic cells do not require major maintenance. Panels have no moving parts and so there is little chance of the solar panels malfunctioning or becoming broken. Generating your own power allows you to save money and be environmentally conscious. Generating solar energy also reduces the amount of greenhouse gases in the atmosphere. Carbon dioxide is the leading cause of global warming and massive amounts of it are released into the air every time from power plants that generate and distribute conventional electricity.
