The Brouchy agrivoltaics project
The Key infos
The agrivoltaics project :
- Location: Brouchy, Somme
- SAU of the farm: 450ha
- Project size: 3ha + 3ha sample
- Agricultural production: Field crops (Wheat, Faba Bean, Potato, Bean...)
On the plot, the plants have particularly suffered from thermal and water stress in recent years, with high thermal amplitudes and especially long periods without water which have impacted plant growth and yields, especially for wheat and potatoes. Global warming is also progressively and steadily bringing earlier harvests. I was looking for solutions to adapt to climate change. Irrigated agrivoltaics is one of the possible answers.

The scores of our demonstrators
-20%
-20% average potential evapotranspiration (Chadeleuf, 2026)
-1,5°C
Une amplitude thermique réduite d’environ 1,5°C sur 24 h en moyenne sur l’année (Brouchy, 2025 et 2026)
96%
96% yield compared with the control plot using ‘Robust’ management, and 90% yield using ‘Intensive’ management (Chadeleuf, 2026)
=
Similar annual yields under the agrivoltaic solution and on the control plot, with better resilience in dry conditions (Souleuvre-en-Bocage, 2024-2025)
-4°C
Air temperature at plant height was reduced by an average of about 4°C under the shade structure, compared to the control plot, during the hottest part of the day (on days when temperatures exceeded 30°C in Chadeleuf, May 2026)
