What are the benefits of agrovoltaics for farmers?
Agrovoltaics—the co-location of solar photovoltaic systems and agricultural production on the same land—offers several key advantages for farmers across energy, economic, and environmental dimensions [1][2].
Yield and Environmental Benefits
Shading from elevated solar panels can reduce soil water evaporation by 14% to 50% and decrease irrigation requirements, helping crops resist extreme weather like droughts [3][4]. Certain crops show improved yields or maintained production under these systems, such as a 20% increase for potatoes in Oregon trials and significant water savings for lettuce in California [5]. However, performance depends heavily on the region and crop; for instance, humid Midwest conditions can reduce maize and soybean yields, while semi-arid areas can boost soybean yields by easing water stress [6].
Income and Land-Use Advantages
Farmers benefit from diversified income through solar lease payments ranging from $300 to $2,000 per acre annually, alongside continued agricultural sales and reduced input costs [7][8]. The approach also optimizes land productivity by achieving dual-use efficiency on the same plot [9].
