河南地区农业温室光伏化升级设计

Photovoltaic Upgrading Design of Agricultural Greenhouse in Henan Province

在传统农业温室基础上进行光伏化改造是推广光伏温室的有效途径之一。以河南城建学院农业温室为研究对象,开展光伏化改造的研究。结果表明:光伏温室系统需要铅酸蓄电池20块;多晶光伏组件每2个一串联,6串一并联,共12块光伏组件,安装角度23°;控制器的每路输入最大电流应该大于12.5 A;选择20 000 W变频转换器逆变器。该温室光伏化改造成本估计为38 200元,预计需要13年可收回成本,创造用电收益12年,预计创造收益34 992元。另外在环保节能等方面具有突出的价值和意义。

Photovoltaic transformation for the traditional agricultural greenhouse is one of the effective ways to promote photovoltaic greenhouse.Taking the agricultural greenhouse of Henan University of Urban Construction as the research object,the research on photovoltaic transformation is carried out.The results showed that the photovoltaic greenhouse system needed 20 lead-acid batteries;two polycrystalline photovoltaic modules were connected in one series,six series were connected in a parallel,the total of 12 photovoltaic modules were fixed with an installation angle of 23°;the maximum input current of each circuit of the controller should be greater than 12.5 A;the inverter of 20 000 W frequency converter was selected.The cost of photovoltaic transformation of the greenhouse was estimated to be 38 200 RMB,it would take 13 years to recover the cost and can generate electricity revenue for 12 years,generating revenue of 34 992 RMB.In addition,it had outstanding value and significance in environmental protection and energy saving.
