Agrivoltaics represents an innovative land management approach that co-locates solar energy generation with agricultural production on the same land area, creating synergistic relationships between crop cultivation and renewable energy harvesting. This dual-use system strategically positions solar panels above agricultural land in configurations that allow sufficient light for crop growth while generating clean electricity, effectively addressing land-use competition between food and energy production while potentially enhancing both outputs through complementary interactions.
Unlike conventional ground-mounted solar installations that typically displace agricultural activities, agrivoltaic systems deliberately integrate these functions through specialized panel arrangements, mounting heights, spacing configurations, and sometimes semi-transparent photovoltaic technologies that enable continued farming beneath and between solar infrastructure. This symbiotic relationship can create microclimates that benefit certain crops through reduced evapotranspiration, temperature moderation, and protection from extreme weather events, while agricultural activities can enhance solar performance through reduced ambient temperatures and natural vegetation management.
Key Components of Agrivoltaic Systems:
- Solar Array Configurations

Despite promising research results, challenges include developing optimal configurations for specific crops and climates, addressing potential mechanization constraints, quantifying long-term soil impacts, navigating complex permitting processes, and establishing appropriate economic models that fairly value both agricultural and energy outputs. Current research focuses on identifying ideal crop-solar pairings for different regions, developing specialized equipment for operation under panels, implementing advanced light management technologies, creating predictive models for system design optimization, and establishing comprehensive sustainability metrics that capture the multifaceted benefits of these integrated systems.
