"This demonstrator is proof that by federating all the players in the ecosystem we are able to create positive externalities in line with our mission. Thanks to this agronomic validation, we hope that many players in the agricultural world will commit to agrivoltaics and thus contribute to the agri-energy transition."
Thierry Blandinières, Invivo Managing Director

This plot of arable land in Valpuiseaux, in the Essonne department of France, is facing a number of challenges: declining yields, landscape issues. The vertical bifacial panels (Next2Sun technology) were installed in 2022 by TotalEnergies and its partner Agrosolutions (an InVivo subsidiary).

VALPUISEAUX (91)

Crops: field crops (moha, wheat, barley, alfalfa)
Crop management: conventional
Technology: vertical bifacial
Power: 111 kWp
Surface area: 0.5 hectare
Design: 288 panels, 10-meter spacing between rows
Control area: no panels next to each row
In operation since: 2022

Focus on vertical technology

This technology makes it possible to maintain agricultural activity while generating renewable electricity from the sun's radiative energy. These vertically-mounted bifacial panels allow solar energy to be captured on both sides, while facilitating field work and the passage of farm machinery.

The innovative nature of this technology also stems from its hourly production profile: the layout of the panels allows for two production peaks: one in the morning and one in the evening.

Agronomic results (2022)

Winter wheat

Increase in yield (+1.9 q/ha or +6.6%, significant) and crop height (+11.5%, significant) compared with the control.

Moha

Increase in yield (+2 q/ha or +18%, significant) and crop height (+15.1%, significant) compared with the control.

Winter wheat

Increase in specific weight between 1.7% and 5.3%.
