光伏农业中光伏与作物匹配策略研究进展OA

This paper systematically reviewed two dominant configurations—photovoltaic greenhouses and open-field photovoltaic systems—of photovoltaic agriculture.We analyzed the matching strategies of diverse crop categories—greenhouse vegetables,grain crops,forage plants,and medicinal plants—with photovoltaic systems in terms of spectral management,spatial layout,and microclimate regulation.The available studies primarily investigated the effect of shading rate on crop yields and quality,as well as the coupling mechanisms between array parameters,microclimate,and energy efficiency.Methodologies ranged from field experiments and modeling simulations to economic analyses.The results indicated that shade-tolerant crops,such as mushrooms and lettuce,could achieve yield increases of 15%-30%under moderate shading.For grain crops,the yield losses remained manageable(<20%)when shading rates were controlled between 25%and 32%.Notably,in arid and hot regions,shading alleviated heat stress,substantially increasing the yields of crops like chili peppers.Furthermore,crop transpiration could reduce the photovoltaic module temperatures by approximately 10℃,thereby enhancing power generation.In conclusion,while photovoltaic agriculture could significantly improve the land equivalent ratio to achieve both food and energy production increases,its widespread adoption faced challenges related to crop adaptability,regional climate variability,and photovoltaic module costs.There was an urgent need to establish standardized co-optimization systems for integrated planting and power generation.
