Solar farms do more than generate clean energy: they can also be designed to work better with the soil, water and vegetation around them. The PV-SMaRT project from the National Renewable Energy Laboratory (NREL) studies five ground-mounted solar sites in the United States to measure stormwater infiltration and runoff, vegetation density, plant species, rooting depth, precipitation and drip-edge runoff from solar panels. The goal is to develop PV-specific tools and best practices that help solar projects manage stormwater and protect water quality more effectively.
This approach shows that solar energy can grow with smarter environmental planning. By considering ground cover, soil type, slope, root depth and how water moves across a site, solar projects can reduce unnecessary impacts and bring more value to the surrounding landscape. For communities, developers and local authorities, the message is clear: better solar design does not only produce electricity, it can also support healthier land and better water management.
