The PV installations of Blaise Cendrars school have been thought, from the beginning, to test and compare performances of various solutions in terms of energy produced and behaviour toward snow. After three years of operation, we make the following conclusions:
- The various de-icing solutions depend considerably on the specific features of the roof and installation: The height of the modules, the tilt/slope of the modules, the space between modules, the ballasting of the installations, are important parameters.
- Among passive solutions, the bifacial HIT Double panel is very promising. The dampproof film impact remains to be validated (an upper tilt of the modules shall enable us to measure this impact).
- The active de-icing solutions did not show their efficiency in our first tests, but the reverse current flows do not seem to damage the health or impact in any way the efficiency of the installations.
