为提高太阳能的利用率同时得到可资利用的热水和电力,将小型贮能式光伏系统与家用平板型太阳热水器结合起来,把光伏电池组件层压在热水器的扁盒式铝合金集热板上,构成一套光伏光热 (PV/T)一体化系统,并在合肥地区进行了自然循环模式下的光电光热性能测试。实验结果表明,在晴朗或多云的天气条件下实验系统日平均热效率可达 40%,日平均发电效率约 9.5%, 系统综合性能效率多在 60% 以上,比单独的光伏或热水系统效率有显著提高。

In order to improve the energy efficiency and to supply hot water as well as electricity, domestic solar water heater was integrated with photovoltaic system by laminating polycrystalline PV module on the absorber plate of water heating system to build a solar hybrid photovoltaic and thermal system (PV/T) in the present study. Test was performed under the model of natural circulation at Hefei. The result shows that the electrical efficiency is round about 9.5%, the thermal efficiency is often higher than 40% and the general energy efficiency is higher than 60% on a single day which is much higher than a pure solar water heating system or a solar PV power generation system.
