【摘要】 提出不同运行模式下太阳电池板倾斜面上瞬时太阳光辐射量的计算方法。在考虑太阳光直射辐射、散射辐射和反射辐射的基础上,针对固定式、单轴高度角跟踪式、单轴方位角跟踪式、双轴跟踪式太阳电池板的不同运行模式,依据倾斜面上瞬时太阳光辐射量分别导出各种运行模式下太阳电池板上的年聚光量计算公式。依据新疆部分地区的气象数据进行仿真,结果表明,与水平安装的太阳电池板相比,上述4种运行模式的太阳电池板年均聚光量分别增加12.70%、21.14%、39.75%、56.44%。更多还原

【Abstract】 A method which calculates instantaneous radiation energy on PV panel ’ s inclination surface in different running modes was presented. In order to obtain calculation formulas of annual accumulated radiation energy in different mode,three key points named direct radiation,diffuse radiation and reflect radiation,were taken into account. The calculation formula was established and applied in four different modes including optimum fixed tilt angle,elevation angle tracking,azimuth angle tracking and two-axis tracking. According to meteorological data in certain area of Xinjiang Uygur Autonomous Region and comparing with horizontal mounting solar PV panels,the simulation results show that annual average accumulated radiation energy on PV panels in four different modes raise 12. 70%,21. 14%,39. 75%,56. 44%,respectively.更多还原
