摘　　要：针对太阳能光伏板输出功率受条件制约的问题,通过Matlab建立了倾斜放置的太阳能光伏板表面所接收的太阳辐射能的数学模型,并实测了太阳辐射能及光伏板的输出功率等数据,探讨了太阳能光伏板的最佳倾角和温度对光伏电板输出功率的影响。研究结果表明,太阳能光伏板在最佳季节倾角下,与水平放置的太阳能光伏板相比,其输出功率提高12%左右;同时,光伏板表面温度每升高10℃,功率减少5%左右。Aiming at the problem of the output power restricted with some condition, optimum angle of fixed solar panel and the influence of temperature to the output power were researched based on modeling solar isolation on the tilt solar panel by Matlah and measurement of the output power. It is found that the output power of the PV panel with a seasonal optimum tilt angle is increased by 12% in comparison with that of a horizontal panel, and the output power is decreased by about 5% when the temperature of the panel surface increases 10 ℃.
