针对光伏电池(PV)-乙烯四氟乙烯(ETFE)气枕一体化建筑体系,设计研制了柔性非晶硅薄膜太阳能电池与三层ETFE气枕一体化系统及测量系统.在太阳辐射强度低的冬季,对该系统进行7次现场实测试验,得到太阳辐射强度、系统电能、耗电、气枕温度和气枕内外压力差等参数.通过试验数据分析得到当太阳辐射强度大于103W/m2时,系统正常工作;在整个试验期间,平均每天太阳能蓄电池蓄电量为49.7W·h,气枕内、外温度差为10.4℃.通过试验验证了PV-ETFE气枕一体化系统冬季应用的可行性,揭示了系统的电气特征、ETFE气枕结构行为特征.
A PV-ETFE mock-up and a corresponding measurement system were developed for the ethylene tetra fluoro ethylene (ETFE) cushion architecture integrated photovoltaic panels (PV). The mock-up was mainly composed of flexible amorphous silicon photovoltaic panels and a three-layer ETFE cushion. Under low solar irradiance in winter, seven on-site tests were conducted to obtain the originally parametric data, such as solar irradiance, generated energy, consumption energy, temperature and pressure difference between the inside and outside of the cushion. The data analysis showed that the system worked smoothly when solar irradiance was greater than 103 W/m2. Average net energy stored by storage batteries was 49.7 W ~ h and temperature difference between the inside and outside of the cushion was 10.4 ~C. The feasibility of the PV-ETFE application was demonstrated. The system electric characteristic and structural behaviors of ETFE cushion in winter were revealed.
