为提高锥形建筑太阳能的收集和利用,提出一种采用瞬时辐射量建立的太阳电池板动态数学模型.按月引入日照系数,通过对太阳电池板上瞬时辐射量的连续积分获得计算周期内的太阳辐射总量.以锥形建筑较多的内蒙古二连浩特地区为例,计算不同坡度圆锥面上太阳电池板不同覆盖面积的太阳辐射量,并以0.1°为坡度增长步长,计算圆锥面上太阳电池板不同覆盖面积的最佳坡度角.仿真计算表明,覆盖面积越大,则最佳坡度角越小、太阳能利用率越低.“,”To improve the efficiency of solar energy collection and utilizing,a dynamic mathematical model of PV panels position was proposed.To improve calculation accuracy,solar radiation coefficient of sunlight by month was introduced.The solar radiation could be obtained by continuous integration of instantaneous radiation on a PV panel in a computation period.Take the example of Erenhot in Inner Mongolia with big number of cone-shaped building.The quantities of solar radiations on PV panels with different slope angels of cone surface and different areas of coverage are calculated.The optimum slope angles of PV panels with different areas of coverage on cone surface were also calculated by taking the gradient step of 0.1°.The results of emulation showed that the bigger areas of coverage and the smaller optimum slope angle,the lower utilization rate of solar energy.
