摘要
选取几个不同纬度、不同海拔的地点,研究了不同形式支架对光伏系统发电量的影响。通过比较可知,随着海拔高度和纬度的提高,可调支架对提高发电量的影响越加明显。文章还比较了应用可调支架和固定支架对电站前期投入和后期运行维护的成本问题。通过经济性分析,提出了在高纬度、高海拔和土地费用低的地区,宜采用可调支架(1年调整4次),在低纬度、低海拔地区,宜采用最佳角度的固定支架的建议。
Selecting several locations of different latitude and altitude, the influences of support bracket form on the output of photovoltaic power generation system have been researched, the results show that with the increase of altitude and latitude, adjustable bracket shows more obvious impact to improve the capacity. The upfront costs and costs of operating and maintenance between two kinds of brackets installation are compared in this article. Through the comparative analysis, it is advised that the adjustable support bracket, which should be adjusted 4 times a year, is available at a high latitudes, high altitude and low cost area of the land, but the fixed support bracket is available at a low latitudes and low altitude.
