English: Popular agrivoltaic systems use photovoltaic (PV) farms for pasture grazing animals. In general, these agrivoltaic systems do not reduce the capital cost of a PV farm and in some cases can increase it. To overcome this challenge this study investigates the potential for retrofitting existing animal fencing on farms to have dual use for vertical-mounted monofacial PV racking. Specifically, this study catalogs types of fences and wind load calculations classified under Risk Category I are run through a new python-based Open Source Wind Load Calculator to determine the viability of fence-based racking throughout the U.S. The base shear force for all the fences are calculated for a range of wind loads from 80mph to 150mph (129 km/h to 241 km/h) and the results are mapped to indicate the number of PV modules between the vertical fence poles a fence can tolerate in a specific location. The results show the required fence type including post and battens in a given area for sheep, goats, pigs, cows, and alpaca to be used for agrivoltaics. Overall, at least one PV module between posts is acceptable indicating a new agrivoltaic system potential that as little as $0.035/kWh for racking on existing fencing. Although the yield for a vertical PV can range from 20 to 76 % of an optimized tilt angle depending on azimuth, the racking cost savings enable fence-retrofit agrivoltaics to often produce lower levelized cost electricity. Future work is necessary to determine the full scope of benefits of vertical PV agricultural fencing on a global scale.
