【摘要】 通过3 k W小型并网光伏发电的试验测试,考察环境因素和太阳辐射在年最差2个月中对系统发电性能的影响。结果表明:环境湿度低于20%,同时环境温度越高,系统的发电性能越好;电池板上的太阳瞬时辐射强度峰值要比水平位置提早出现,且在同一时刻,其瞬时辐射强度也比水平位置的大;太阳累计辐射强度与当日系统发电量呈线性正相关。更多还原

【Abstract】 Through the test of 3 k W small-type grid-connected PV power generation system, this paper studied the effect of environment factors and solar radiation in the worst 2 months of a year on electricity generation performance of the system. The results showed that the higher the ambient temperature was with the environmental humidity lower than 20%, the better the electricity generation performance of system was. And the solar transient radiation intensity peak on solar panel would occur earlier than in the horizontal position, and at the same time, the transient radiation intensity was bigger than that in the horizontal position. Solar total radiation intensity was linear positive correlation to the electric energy production of the system in the same day.更多还原
