The photovoltaic effect is the particular properties of some semiconductors, normally enough silicon to produce electricity when struck by photons (ie exposed to light). The photovoltaic panels are a must for those who want to throw in the lucrative world of "renewable". In particular, our module, small, light and cheap is a true jewel of technology within the reach of all.
Energy - clean and free - the sun - Photovoltaic technology to harness the energy radiated by the sun to produce electricity. Photovoltaic systems do not require maintenance, allow it to produce electricity as needed, last long.
A photovoltaic system consists of:
Photovoltaic cells formed from slices of a semiconductor material (silicon) which are formed into modules, then in panels, then in strings connected in parallel.
A control system which can be a "controller" or "charge regulator" to charge the batteries or a grid connected inverter which leads the energy produced directly into your home network by reducing the bill!
a possible energy storage (batteries)
Among the various types of photovoltaic systems can be distinguished:
The "off-grid" is used to carry electrical energy where comes the Enel network: accumulate the energy in batteries for use upon request.
Systems "Grid Connected" (grid-connected): enter the energy produced in the network thus reducing the one to buy from Enel.
