Potential of photovoltaic energy
The quantity of electric energy produced by a photovoltaic system depends on many factors, for example:
1) surface of the plant;
2) position of FV modules in the space ( inclination angle depending on the horizon and angle of inclination);
3) value of solar radiation which bear on the site of installation;
4) efficiency of FV modules;
5) efficiency of electric components for the transfer and transformation of energy ( BOS);
6) temperature.
The photovoltaic system produces electric energy in continuous electricity, and domestic and commercial users distribute alternate electricity. It’s need the transformation of energy from the continuous one to alternate one, thanks to the “ Invert”.
It is possible to act on some parameters, only not on solar radiation, in order to maximize the efficiency of the system with a suitable project, choosing of a right FV modules and other components and thanks to an optimal modules orientation.
With an optimal system configuration it is possible to indicate the annual production for every kWp installed depending on its geographical collocation.
