What to know about Agrovoltaic systems can save water, generating energy and making tomato cultivation more sustainable at the same time

A study from the University of Seville and Polytechnic University of Madrid demonstrates that agrovoltaic systems can reduce tomato cultivation water use by 50% while maintaining sustainable land use. The research compares irrigation methods and finds that while yield decreases by 20% under solar panels, the combined system improves water productivity and energy generation efficiency.

What happened

Agrovoltaic systems can save water, generating energy and making tomato cultivation more sustainable at the same time Gaby Clark scientific editor Robert Egan associate editor Researchers from the University of Seville (US) and the Polytechnic University of…

Why it matters

The study, carried out in Madrid and Seville during the spring of 2024, evaluated the use of agrovoltaic systems and regulated deficit irrigation to optimize water resources in tomato cultivation.

Common ground

The results show that, although using less water reduces the volume of the harvest, the overall outcome is a more efficient and sustainable process.

Perspective signals
