The challenge
An industrial sandwich-panel roof with nine 15° slopes, and a factory in full operation. The goal was to make the most of the available area without drilling the roof or stopping production.
Industrial solarA 575 kW solar plant on the roof of the Prozis industrial unit, so the factory uses the energy it produces.

An industrial sandwich-panel roof with nine 15° slopes, and a factory in full operation. The goal was to make the most of the available area without drilling the roof or stopping production.
A self-consumption unit with 600.48 kWp of panels and 575 kW of grid connection. The project estimate points to around 800 MWh per year, produced and used on site.
In-house electrical design, signed by a chartered engineer, with a PVSol simulation to choose the number and orientation of modules on each slope.
864 modules of 695 Wp in 45 strings, connected to 5 Huawei SUN2000-115KTL-M2 inverters.
Modular aluminium structure clamped to the trapezoidal roof profile: no drilling at all.
Monitoring with SmartLogger and Smart Meter, to follow production and consumption remotely on a web platform.
