Deines, T. (2025, July 10). In the Sweltering Southwest, Planting Solar Panels in Farmland Can Help Both Photovoltaics and Crops. Inside Climate News https://insideclimatenews.org/news/10072025/agrivoltaic-solar-southwest-farmland/
Inside Climate News reported in July on research from the University of Arizona about agrivoltaics in desert farming. Scientists have been running experiments for seven years to see how growing crops underneath solar panels affects both the plants and the panels. They found some surprising benefits being the shade from solar panels actually helps crops grow better in hot and dry climates and cuts irrigation needs by more than half. In the Tucson desert, researchers were getting basil leaves as big as their palm. The reason this works so well is that the panels create shade, which reduces how fast water evaporates from the soil, so moisture stays available to plants longer. Plus having plants growing underneath actually makes the solar panels work better because of the cooling effect from the vegetation helps keep the panels from overheating.
This article caught my attention because it shows how creative thinking can solve what seemed like competing problems. A lot of people worry that building solar farms means losing farmland and reducing food production, but agrivoltaics proves that’s not necessarily true. You can generate clean electricity and grow food on the same piece of land at the same time. For the drought stricken Southwest, this is especially important because climate change is making the region hotter and drier every year. The article mentions that solar panels work best around 75 degrees fahrenheit, but in the desert they get way hotter, which reduces their efficiency. Growing crops underneath helps cool them down. At the same time, the crops benefit from protection against heat stress and need way less water. However, the article also discusses some challenges. Many large scale farmers are skeptical because agrivoltaic systems require more labor and different equipment which increases costs. There’s also concerns about taking productive farmland out of traditional use. I think this shows that even good environmental solutions face real economic and practical obstacles. We need more research and probably better financial support to help farmers transition to these systems. It’s a good reminder that addressing climate change and resource scarcity requires innovation and flexibility, not just sticking with old methods.
