Photovoltaic Panel System a green Energy Source:>/span>

The arrangement is mounted like the solar panels on the house roof. It converts the sunlight into solar electricity power instead of heat.
The Photovoltaic modules includes a type of silicon which can be structured as:

- mono-crystalline

- multicrystalline

- or amorphous

The light of the sun generates in the solar cell an electric tension which can be captured on the surface.
This effect is called Photovoltaic (photo = light, volt = tension).

Solar cells by the size of cm 10/10 can produce approx. 1 watt of electricity.
A standard arrangement of 10 sqm photovoltaic modules deliver 1,000 watts of electricity, this corresponds to 1 kW.
This result depends on the intensity of the solar irradiation; the declared nominal result is reached with good irradiation terms.
The produced electric energy is converted in the so-called change judge, into net-compliant electricity.

Construction types:

a. Photovoltaic brick:

Solar roofing tiles are Photovoltaic module (PV modules) in the traditional roofing integrated. The single “bricks” are united by stick-connections.
Solar roofing tiles are offered since the beginning of the 90s by different manufacturers to allow an optically responding integration of solar power arrangements in the roof surface.
The number of the PV module types considerably increased in the course of the years.

Photovoltaic modules from 3 watts per element up to 200 watts in the biggest solar roofing tile.

b. Mono-crystalline solar cells distinguish themselves by a steady crystal lattice structure of the silicon atoms. They have a steady dark, almost black, smooth surface, the efficiency lies at 18%.

c. Polycrystalline potovoltaic modules own a crystal lattice structure, steady in sections of the silicon atoms. The efficiency lies at 18% max. The production is easier and cheaper than the mono-crystalline cells.
Thin layer modules are produced by steaming the silicon onto a carrier layer (glass).
The silicon atoms are arranged irregularly and show no recognizable structure on the surface. The efficiency lies with max. 8%. The production costs are relatively low.

d. Cooled Photovoltaic (CooIPV)

While traditional Photovoltaicmodul arangements are usually used solely in the production of solar electric power, with COOIPV-arrangements heat is generated at the same time.
With a heat exchanger intergrated in the Photovoltaicmodul, solar heat is transferred with carrier liquid and stored. Therefore the Photovoltaicmodule is cooled and with it the stream production increased with up to 30%.
