Solar Photovoltaic System

Listing ID #3044853

Solar electricity is created by using Photovoltaic (PV) technology by converting solar energy into solar electricity from sunlight. Photovoltaic systems use sunlight to power ordinary electrical equipment, for example, household appliances, computers and lighting. The photovoltaic (PV) process converts free solar energy � the most abundant energy source on the planed � directly into solar power. Note that this is not the familiar �passive� or solar electricity thermal technology used for space heating and hot water production.
A PV cell consists of two or more thin layers of semi-conducting material, most commonly silicon. When the silicon is exposed to light, electrical charges are generated and this can be conducted away by metal contacts as direct current (DC). The electrical output from a single cell is small, so multiple cells are connected together and encapsulated (usually behind glass) to form a module (sometimes referred to as a �panel�). The PV module is the principle building block of a PV system and any number of modules can be connected together to give the desired electrical output.
PV equipment has no moving parts and as a result requires maintenance. It generates solar electricity without producing emissions of greenhouse or any other gases, and its operation is virtually silent. PV systems supply solar electricity to many applications, ranging from off grid rural electrification systems, operation of railways signals, systems supplying power to buildings, systems supplying power to garden lights or to remote telecom relay stations. The main area of interest in the India today is grid connect PV systems. These systems are connected to the local solar electricity network. This means that during the day, the solar electricity generated by the PV system can either be used immediately (which is normal for systems installed on offices and other commercial buildings), or can be sold to one of the electricity supply companies (which is more common for dom
