Photovoltaic systems connected to the grid
They allow you to become a producer of electricity. The photovoltaic modules then become an integral part of the housing envelope (roof, canopy, cladding, curtain wall).
The system produces direct current, which is transformed into alternating current by an inverter and then injected into the public distribution network. An electric meter measures the energy supplied to the network. A contract is signed with E.D.F. who agrees to buy back your production.
