Operating principle of a photovoltaic generator :

photovoltaique desc-2


The photovoltaic panels, or modules, directly convert the light radiation from the sun into electricity, and generate a current.
To be used on the electricity grid, the DC must be converted using the inverter into alternating current.
The energy produced can be consumed by the building on which the generator is installed, or returned to the public distribution system.
SOFTEN Photovoltaic generators Industries can thus reduce the energy bill of that place.


The building is normally equipped with a power meter measuring the energy consumed.
As part of a photovoltaic system, a second meter is installed by STEG to measure the energy produced by the plant and returned to the network.
A sales contract is then established with the user.
