Weight-sensitive PV for France’s food logistics

For a logistics giant with 236 platforms and warehouses, energy transition begins at home. See how novotegra was used to mount a structurally sensitive rooftop. With weight restrictions to consider, proper planning was critical.

Setting the scene:

STEF are a French food logistics player with a huge presence across the EU. Their ongoing energy transition efforts are seeing them install photovoltaic modules on warehouse rooftops for self-consumption. Some sites are already aiming for as close to 100% self-generated energy use as humanly possible.


Meeting the challenges:

At STEF’s Donzenac site, novotegra was used to mount photovoltaic modules across 1850 m2 of flat roof. The warehouse’s construction meant that we had to proceed carefully with a limited surface load. Using Solar-Planit, we could truly optimise every square metre of available space.


The result:

STEF Donzenac now produces 237 kWp of clean energy for this critical nexus in France’s food infrastructure. All this was achieved across a planning and implementation period of only six months. The group are now well on their way towards their goal of 100% low-carbon energy by 2025.

“Some other solutions simply can’t handle a 25kg per m2 load on projects like this. novotegra can. Even the most sensitive sites are suitable for rooftop PV.”
