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.

Similar annual yields under the agrivoltaic solution and on the control plot, with better resilience in dry conditions (Souleuvre-en-Bocage, 2024-2025)

Up to -7°C under agricultural canopy during a recorded heat peak (Amance and Brouchy, 2025)
-1.4°C on average on the hottest days
