Austrian agrivoltaic site achieves 14% higher winter wheat yields during 2026 drought

EWS's Sonnenfeld research site in Austria recorded 14% higher winter wheat yields in 2026 compared to control plots, measured in 12-meter-wide strips with solar panels.

EWS's Sonnenfeld research site in Austria recorded 14% higher winter wheat yields in 2026 compared to control plots, measured in 12-meter-wide strips with agrivoltaic PV arrays. This increase occurred during a dry summer season, though EWS states the finding is under final evaluation with a complete report expected by year-end 2026. Earlier 2024 data showed a similar 10% yield boost in comparable strips.

The system demonstrates practical integration: EWS operates a 4.58 MW agrivoltaic project in Pischelsdorf am Engelbach that allocates 80% of land to agriculture, 18% to biodiversity measures like flower strips and bee pastures, and 2% to solar components. Soybean growth at this site also remained resilient during the 2026 drought, though yield data remains unpublished.

This result moves food security in space-constrained regions by showing agrivoltaics can simultaneously boost crop yields and generate solar power during drought conditions—critical for areas facing land scarcity and climate volatility. The dual benefit directly supports sustenance needs where agricultural land is limited.

EWS expects final analysis by December 2026. Longer-term studies are needed to confirm these effects beyond this specific site and 2026 season. Yield gains depend heavily on site characteristics, crop type, weather, and soil conditions during installation—meaning results may not translate to other regions or climates. The 14% figure applies only to 12-meter cultivation strips and the 2026 harvest season.
