Dr roaf is an architect at oxford brookes university and has designed a solar house fitted with photooltaic cells 罗芙博士是牛津布鲁克斯大学的建筑师，她设计了一个装有光生伏打电池的太阳能住宅。
Currently pv is highly expensive ( dr roaf ' s roof cost 25 , 000 in 1995 ) but the price is sure to decrease as more people become energetically self - sufficient 目前光生伏打电池是很昂贵的（罗芙博士的屋顶在1995年值2 . 5万英磅） ，不过随着更多的人成为能源自给者，价格肯定会逐渐降低。
Photovoltaic ( pv ) panels produce electricity directly from sunlight using silicon cells , with no moving parts . it drives the pump through series of new technologies of electronics , motors , control units and different modern devices to bring wafer up from river , lake or deep well . the system involves optical , mechanical and electronic theories and has an multi - across discipline property of studies 光伏水泵系统是直接利用太阳电池光生伏打效应发电，之后通过一系列电力电子、电机、水机等控制及执行环节从而在江河湖泊或深井中实现提水的系统，该系统是光、机、电、控制技术等多学科交叉、结合的体现。
