太阳能建材技术的研究与开发(Ⅰ)——光伏屋顶热性能的调查

TECHNICAL RESEARCH AND DEVELOPMENT OF SOLAR ENERGY BUILDING MATERIALS (Ⅰ):THERMAL INVESTIGATION OF INTEGRATED PV ROOF

为了对综合利用生态能源技术进行研究和发展 ,上海交大太阳能研究所建造了JD - 0 1号生态能源房。根据在大规模应用中节省建材和施工费及追求建筑美观的意图出发 ,实验性地开发了太阳能屋顶一体化技术。为了调查太阳电池组件作为建筑模块使用时其背面温度的上升规律及对太阳电池性能的影响 ,供今后设计类似系统时参考 ,实际测定和讨论了太阳电池背面温度与太阳辐照度、环境温度的关系 ,结果表明有自然通风通道的光伏屋顶的温度特性与支架布置型太阳电池方阵基本相同。

We constructed JD 01 eco energy house to study and develop the synthetic technology of eco energies.According to the intention to save building materials and construction fees and to pursue the beauty of buildings at large scale application,we developed a technique of integrated PV roof experimentally.The PV modules for integrated PV roof may experience temperatures high enough to reduce the electrical output.For investigating the temperature effects and for giving the data to design similar systems,the temperature behind the PV roof,irradiation and ambient temperature are tested and discussed.It is shown that the thermal performance of the PV roof with natural draft ventilation is much the same as that of field PV array.
