摘　　要：搭建了4套光伏发电系统:单晶V形槽聚光、多晶V形槽聚光、单晶平板、多晶平板光伏发电系统,进行实验测试。结果表明:在同等气象条件下,不论使用单晶硅太阳能电池还是多晶硅太阳能电池,V形槽聚光光伏发电系统最大电功率和平均电功率均大于平板光伏发电系统。其中,单晶V形槽聚光光伏发电系统最大电功率和平均电功率均大于多晶V形槽聚光光伏发电系统。单晶V形槽聚光光伏发电系统的最大电效率和平均电效率相对于单晶平板光伏发电系统分别提高3.70%和1.48%,多晶V形槽聚光光伏发电系统的最大电效率和平均电效率相对于多晶平板光伏发电系统分别提高3.13%和1.99%。单晶V形槽聚光光伏发电系统太阳能电池表面最高温度和平均温度相对于单晶平板光伏发电系统分别降低1.13℃和3.27℃,多晶V形槽聚光光伏发电系统的太阳能电池表面最高温度和平均温度相对于多晶平板光伏发电系统分别降低0.95℃和3.61℃。Four sets of photovoltaic power generation systems were built:monocrystalline V-trough concentration,polycrystalline V-trough concentration,monocrystalline flat panel and polycrystalline flat panel photovoltaic power generation systems,and experimental tests were carried out.The results show that under the same meteorological conditions,whether using monocrystalline silicon solar cells or polycrystalline silicon solar cells,the maximum and average electrical powers of the V-trough concentrated photovoltaic power generation systems are greater than those of the flat panel photovoltaic power generation systems.Among them,the maximum and average electrical powers of the monocrystalline V-trough concentrated photovoltaic power generation system are greater than those of the polycrystalline V-trough concentrated photovoltaic power generation system.The maximum and average electrical efficiencies of the monocrystalline V-trough concentrated photovoltaic power generation system are 3.70%and 1.48%higher than those of the monocrystalline flat panel photovoltaic power generation system,respectively.The maximum and average electrical efficiencies of the polycrystalline V-trough concentrated photovoltaic power generation system are 3.13%and 1.99%higher than those of the polycrystalline flat panel photovoltaic power generation system,respectively.The maximum and average surface temperatures of the solar cell in the monocrystalline V-trough concentrated photovoltaic power generation system are 1.13℃and 3.27℃lower than those in the monocrystalline flat panel photovoltaic power generation system,respectively.The maximum and average surface temperatures of the solar cell in the polycrystalline V-trough concentrated photovoltaic power generation system are 0.95℃and 3.61℃lower than those in the polycrystalline flat panel photovoltaic power generation system,respectively.
