Our agrivoltaic experimentation program

At TSE, we are determined to reconcile sustainable agriculture, green energy, the restoration of biodiversity and the preservation of water resources.

Our vision of agrivoltaics

Agrivoltaics is a major opportunity for France. The aim is not simply to combine photovoltaic production and agricultural production on the same land, but also and above all to create synergy between the two activities. This new practice provides protection to crops and improves of the well-being of farm animals.

Agrivoltaics also secures the economic model of farms by offering them a source of additional income, without diverting them from their primary vocation. The agrivoltaic solutions we develop, hand in hand with the agricultural world, produce the best of solar energy for the best of crops.

Agronomic monitoring of pilot sites

Our ambitious experimental program is currently testing a wide range of plant species and varieties, as well as several types of farming throughout France.

With numerous pilot sites and more than 70 hectares throughout France, our agrivoltaic demonstrator program is the largest in the world. These sites follow a scientific test protocol co-constructed and conducted with our teams of agricultural experts in plant and animal biology and our scientific and agricultural partners.

Over a period of 3 to 9 years, our agronomic trials will demonstrate the relevance and effectiveness of this concept and quantify the expected beneficial effects on different farms and different crops, yield and quality, and adjust varieties, crop management, and rotations over the course of the experiment. At each pilot site, testing is carried out on an area covered by an agrivoltaic system and on a control area using the same procedures.

Results of our demonstration program

-75%
-75% fewer days of stress over the course of the cycle (Amance, 2022)
2/3
Un nombre égal ou supérieur d'heures dans des conditions climatiques optimales sous canopées pour 2 des 3 indicateurs pris en compte (Amance, Verdonnet et Brouchy, 2024)
=
Up to 25% difference in yield between varieties under the canopy and 19% on the control plot (Amance, 2022)
0%
Le rendement du mélange prairial, au mois le plus chaud (août) sous la canopée a atteint le double du rendement de la zone témoin et a été équivalent de juin à octobre (Souleuvre en Bocage, 2024)
-2°C
-1 à -2°C lors des journées chaudes et ensoleillées (pour les T° aériennes extrêmes) (Amance, 2022 et 2024)
-1°C à 30 cm de profondeur du sol de juin à mi-août (Amance 2024)
