【摘要】 分析光伏阵列阴影随时间的变化关系以及相邻光伏阵列间隔距离的确定方法。在光伏平板以最佳倾角安装并设定相邻光伏阵列间隔距离的前提下,以合肥地区为例,分析阵列间隔处光照随时间的分布规律以及可回收的能量。提出光伏阵列间隔处太阳能的复合抛物槽(CPC)光热利用方法,并分析CPC有效接收面积与能量收集效率的关系。更多还原

【Abstract】 Shadow length of PV array varying with time was investigated,and the minimum row spacing betweenadjacent PV arrays was determined. For the case of solar panels mounted at the optimum angle and given array rowspacing at Hefei,the variation of solar energy in the array row spacing with time was analyzed,and the recovery solarenergy was evaluated. A compound parabolic concentrator(CPC)system was proposed to utilize solar energy in PV arrayrow spacing. The effective area of CPC and the collecting efficiency is presented.更多还原
