As we march toward a world where energy is both abundant and sustainable, we’re still in the early days of identifying win-win methods of deployment. One such method is “Agri-PV.” Here’s the problem statement – land is typically used exclusively for crops or for solar panels.
However, it is possible to merge the two with solar panel shaded agriculture. It can provide temperature regulation and optimize water usage while providing electricity for the farmer.
This, of course, works differently based on the type of crop. So, the type of Agri-PV system depends on how much shade/sunlight the crop needs.
As you can see from this study in Central Europe, it works better for berries and fruits (which yield more with more shade) while also providing the additional benefits of solar power.
I think of these kinds of systems every time I drive past the California central valley. When I look at the uncovered canals bathed in sunlight, I think of the amount of water that is lost in the system to evaporation. Covering these canals with solar PVs (a.k.a. “Project Nexus“) would reduce the water loss for farmers while providing electricity for the same communities at scale.
Agri-PV and Project Nexus are great examples of the experimentation needed as we make this energy transition. I’m excited for all that lies ahead.
