The REGACE project operates six test sites in Germany, Austria, Italy, Greece, and Israel, covering diverse crops and climatic conditions to validate the technology’s viability across different environments. These sites are testing an innovative responsive sun-tracking agrivoltaic system integrated with CO₂ enrichment inside greenhouses to enhance crop yields and electricity production year-round.
Highlights of the testing sites and approach include:
- Diverse climatic and crop conditions: Testing in multiple countries ensures the technology adapts to varying light levels and climates, with CO₂ enrichment compensating for reduced photosynthesis under lower light.
- Greenhouse adaptation: The responsive tracking technology is customized for different greenhouse types at each site, including structural surveys and installation guidelines to optimize fit and performance.
- Technology features: The system uses a sun-tracking mechanism to extend solar panel exposure throughout the day, increasing electricity generation especially in areas with less sun exposure.
- CO2 enrichment strategies: Besides standard bottled CO₂, alternative enrichment methods such as mulch and CO₂ bags are explored to provide sustainable and cost-effective solutions compatible with organic production
