Lessons Learned from Three Agrivoltaic Installations in New Jersey

Agrivoltaics is a new technology that has the potential to positively impact commercial farming by combining agricultural practices with the generation of solar energy. While some yield reduction is to be expected, resulting from less sunlight reaching the plant canopy and ground occupied by support structures, the generated electricity provides a low-risk supplemental income to farmers. In order to combine farming with electricity generation, agrivoltaic systems use a lower ground coverage ratio compared to normal solar farms and the PV panels are often mounted higher above the ground in order to facilitate the movement of agricultural equipment and to reduce the contrast between shaded and non-shaded areas. With funding provided from the state of New Jersey and the New Jersey Agricultural Experiment Station (NJAES), we designed and installed three unique agrivoltaic research systems at Rutgers/NJAES farms. These projects were recently completed and are generating electricity that is exported to the grid. This paper discusses the lessons we have learned along the way, including all the steps necessary to see an agrivoltaic project through to completion.

Shading and Energy Impacts for Farmer-Friendly Agrivoltaics Arrays

When designing agrivoltaic solar arrays, farmers’ natural row tilling directions might be reasonable choices for array alignment, especially in cases where the tilling direction helps prevent soil erosion or has other benefits for the farmer’s operations. We examined the light field and energy production effects when installing arrays that have azimuth values that deviate from the typical ideal for three important array types: fixed-tilt, single-axis tracking, and vertical bifacial arrays. On a fractional annual energy production basis, though, all three array types lose very little output when rotated away from their ideal. This offers farmers and solar developers a wider range of system design to possibly align solar array rows with the farmer’s preferred tilling directions.
