The agrivoltaics (AV) farm are traditionally configured as interposed photovoltaic (IP-AV) panel arrays on crops, however  IP-PV requies heightened panel fixtures to provide clearance for cropping machines. This complicates the architecture and increases the price. One wonders if one could achieve the same integrated output (with same crop-loss) by subdividing the land for panels and crops for a juxtaposed (JP-AV) setup.  If viable, the JP-AV configuration would simplify AV design considerably. Here we have used state-of-art PV and crop modeling tools (i.e. Purdue Solar Farm Simulator and APSIM) to numerically explore the design considerations of these AV setups in China and India. We find that for a finite land constraint, IP-AV will always yield higher output and the design can be optimized to produce 4 times higher energy than JP-AV. In both cases, output per panels are comparable. IP-AV essentially allows for more panels to be installed on the finite land while maintaining the predefined or allowable crop-loss. These results have important implcations for policymaker in deciding on renewable energy readmaps for a country with limited lands and PV equipment manufacturers in deciding the creating innovative trackers for AV systems.
