How to assess bifacial PV system performance on sloped terrains
Scientists have developed a precursor formulation for different PV simulation tools that can help calculate the expected performance of solar farms deployed on hilly slopes. Validation tests against an experimental setup showed an error of less than 3%.
All agrivoltaic system designs at a glance
Researchers in Sweden and Italy analyzed the economics of one-axis, vertical, and elevated PV systems for agrivoltaic applications, finding that overhead agrivoltaic systems may perform better the further south they are installed. The discounted payback period and levelized cost of electricity were also calculated and compared.
