PhotoVoltaic Glass

Photovoltaic glass is a special kind of glass that easily transforms the energy of the sun into electricity. They are on the most of occasions used in arrays.

Photovoltaic arrays are often associated with buildings: either integrated into them, mounted on them or mounted nearby on the ground.

Arrays are most often used on existing buildings, usually mounted on top of the existing roof structure or on the existing walls. Alternatively, an array can be located separately from the building but connected by cable (usually underground since it allows for more design choices) to supply power for the building.

In 2010, more than four-fifths of the 9,000 MW of solar PV operating in Germany were installed on rooftops. Building-integrated photovoltaics (BIPV) are increasingly incorporated into new domestic and industrial buildings as a principal or auxiliary source of electrical power.

Usually, an array is incorporated into the roof or walls of a building. Roof tiles with integrated PV cells are also common.

A 2011 study using thermal imaging has shown that solar panels, provided there is an open gap in which air can circulate between them and the roof, provide a passive cooling effect on buildings during the day and also keep accumulated heat in at night.

The power output of photovoltaic systems for installation in buildings is usually described in kilowatt-peak units (kWp).

With this in mind, having a Photovoltaic array as power for your house is probably a really good idea.
