Solar power's biggest problem is land. It takes too much potentially arable land away from the food system to generate enough energy to make it worthwhile. However, agrivoltaics (APV) combines agriculture and photovoltaics (solar panels) on a single piece of land. Some experiments suggest that the two can act synergistically, improving the productivity of each and helping us lower the strain on our food and energy systems. This article examines how APV works and what benefits it may confer.
