What is a renewable energy source?

The renewable energy sources are the natural sources able to renew either partially or fully upon successive consumption either alone or with the help of humans.

Why should we use the renewable energy sources?

Use of the renewable energy sources is environmentally beneficial, especially due to minimum effect on environment. Use of photovoltaic (PV) technology for production of electricity from sunlight produces no pollution. Because its source - sunlight - is freely and normally accessible, continuous access to the source is ensured. The more people are involved in this renewable energy source the lower are costs for production of products used for solar energy production. Production of the solar energy becomes accessible for everybody. Involvement of a relatively new and modern industry helps producing of new job opportunities that improve economy.

What is "PV"?

PV is an abbreviation for photovoltaic (photo=light, voltaic=electricity). PV is the technology based on semiconductor that converts light energy into direct current, uses no rotary components, requires no conventional fuels and produces no pollution.

What are types of PV?

Vast majority of energy units used from 1955 is made from mono-crystalline or poly-crystalline silicium although some producers produce big energy units from amorphous silicium (technology of thin layers). Most of consumables powered by the solar cells uses the thin layer amorphous silicium PV. Satellites and other space applications use mono-crystalline silicium, mono-crystalline gallium arsenite and test materials from thin layer materials. Some companies produce thin layer cells from cadmium telluride (CdTe) and other semiconductor materials, however they are at the very beginning of the research process.

What is a photovoltaic system?

PV systems produce electricity from solar energy. A photovoltaic cell produces direct current electricity by picking up electrons released by interaction of solar light and semiconductor material inside the photovoltaic cell. The photovoltaic system saves costs for electricity. Electricity produced by photovoltaic systems is clean, renewable and reliable. Under our conditions, the photovoltaic systems are usually connected to central electric energy grid where they may be used in the future to balance increased electricity consumption level at daytime.
