光伏发电技术在温室中的应用形式研究

Research on the Application Forms of Photovoltaic Technology in Greenhouse

因土地资源限制、常规化石能源污染环境和设施农业迅速发展等原因,太阳能光伏发电技术与温室的结合得到广泛应用。为了探究太阳能光伏组件的铺设对温室内部环境的影响,总结归纳了国内外学者对不同种类的光伏温室在光伏覆盖面积和排布形式方面的研究成果,得到晶体硅光伏温室覆盖率20%和非晶硅光伏温室覆盖率30%左右时对温室内作物生长影响较小,适当的光伏覆盖面积还可以提升作物的品质,并且在炎热的夏季能够起到很好的遮阳效果。在文献研究基础上,创新地将薄膜光伏电池用于温室外遮阳系统,并且通过可旋转的光伏遮阳板,根据温室对光的实时需求自由调节遮光率。

Due to land resources constraints,pollution of conventional fossil energy and the rapid development of agricultural facilities and other factors,the combination of photovoltaic generation technology and greenhouse has been used widely. In order to explore the influence of photovoltaic modules on the internal environment of greenhouse,coverage area and configuration mode of different kinds of photovoltaic greenhouse investigated by researchers at home and abroad was summed up. The result showed that crystal silicon photovoltaic greenhouse coverage of about 20% and amorphous silicon photovoltaic greenhouse coverage of about 30% have little effect on the growth of crops in the greenhouse,and appropriate photovoltaic coverage can enhance the quality of crops and play a good shade effect in the hot summer. Based on these,the innovative use of thin-film photovoltaic modules for the external shading system of greenhouse,can adjust the shading rate according to the greenhouse real-time demand for light by the rotating photovoltaic sunvisor.
