Abstract

The effects of agrophotovoltaics （APV） system on the local microclimate （e.g. field microclimate） are poorly understood although rapid increasing APV in the world. A meteorological observation system had be integrated for monitoring radiation and meteorological factors at three sites inside and outside of the PV plant （i.e. 1.5 m above the PV arrays inside, under the PV arrays inside, 100 m distance away outside PV station boundary as a reference site）. From October 2021 to September 2022, synchronization microclimate data at the three sites were continuously measured and collected at the interval of 30 minutes. Our results showed that during the day, PV arrays caused net radiation changed into opposite direction under the PV arrays and net radiation above the PV arrays weakened by 7% compared to the reference site. Specially, the albedo under the PV arrays was 0.32-0.45, bigger than that at the reference site. The PV arrays could promote air temperature and humidity. The daily air temperature under the PV arrays is averagely risen by 0.23 ℃ compared with the reference site. Further, air temperature change under the PV arrays could maximally rise up to 0.83 ℃ during the day. We also found the daily relative humidity under the PV arrays was up to 2.0% wetter than that at the reference site. However, the daily temperature range （DTR） under the PV arrays in autumn decreased by up to 5.06 ℃, possibly leading to less accumulation of organic matter and sugar in crops. These data provided evidence to support positive agricultural measures to avoid the narrowed DTR’s negative effect on the crops. The static wind frequency （SWF） was used as an indicator to identify PV arrays impact on the flow field. SWF under and above the PV arrays were 50% and 7%, both higher than SWF at the reference site, respectively. The results can provide technological support for the APV’s development and management.
