摘要
为提高PV/T系统太阳能利用率,同时获得可利用的热水和电力,将铝合金背板型单晶硅光伏组件和自行设计制作的不锈钢扁盒式集热板相结合,用导热硅胶加以粘接制成新型光伏光热一体化(PV/T)复合系统,该系统实现了光伏组件与集热板之间良好的粘接性、绝缘性和热传导,并在昆明地区对系统进行测试,分析了系统在不同水箱水容量及不同天气工况下运行的光电光热性能。结果表明,系统在75kg水箱水容量(m)晴天工况下运行效率更高,系统的平均电效率、热效率、综合效率及综合性能效率分别在14%、37%、51%、70.72%左右,与系统在50kg水箱水容量晴天或75kg水箱水容量多云工况下运行相比,综合性能效率约提高了11.86%或2.09%。与独立的光热或光伏系统相比,具有占地面积小、太阳能利用率高、更经济等优势。
A novel hybrid photovoltaic /thermal solar system, which combining flat stainless steel box as solar heat collectors with aluminum alloy backplane monocrystalline silicon PV components, and using the thermally conductive silica-gel for adhesion, was designed to improve the energy efficiency and to supply hot water and electricity. The system performed good adhesion, insulation and heat conduction between the collector and PV module. The electrical and thermal efficiency of the system are tested through experiments conducted in Kunming area with different water mass and under different conditions. The results show that the total efficiency and general energy efficiency of novel PV/T system is higher in 75kg water mass sunny weather.Its electrical efficiency, thermal efficiency, total efficiency and general energy efficiency are 14%, 37%, 51%, and 70.72%, respectively. Compared with in 50kg water mass sunny or 75kg water mass cloudy weather, the general efficiency has been enhanced by 11.86% or 2.09%. Compared with pure PV system or the nature circulation of the solar water collector, The novel PV/T systems has several advantages, including smaller occupied area, higher utilization of solar energy and lower expenditure.
