英文摘要	Ground-mounted photovoltaic (PV) arrays of an agrivoltaic system (AVS) creates shade in the interspace areas as well as below PV areas of the AVS. Therefore, availability of photosynthetic photon flux density (PPFD) and daily light integral (DLI) in the AVS is negatively affected, which restricts optimum crop growth and yield. Therefore, in this study, spatial and temporal variation of PPFD and DLI in the AVS (105 kW(p)) developed at Jodhpur, India were quantified. Among three designs of PV arrays in the AVS, the proportion of shaded area in interspace was found highest in single row design and lowest in triple row design. The amount of PPFD varied widely in the AVS and even within the shaded area. Following semivariogram and kriging approach, spatial variation of PPFD and DLI was quantified within the AVS. Highest amount of PPFD was observed near noon in unshaded areas (1295 mu mol m(-2) s(-1)) whereas lowest amount was observed during morning at below PV array (24 mu mol m(-2) s(-1)). Based on the maps of PPFD and DLI, three distinct zones in the AVS were identified: (i) below PV array (DLI = 0-5 mol m(-2) d(-1)), (ii) interspace area with partial shade (DLI = 5-20 mol m(-2) d(-1)) and (iii) interspace areas with no shade (DLI = 20-30 mol m(-2) d(-1)). Knowledge of spatial and temporal variation of PPFD and DLI may help in selection of suitable crops for the AVS. (C) 2021 IAgrE. Published by Elsevier Ltd. All rights reserved.
