世界能源的短缺以及环境污染已成为当今日益严重的问题,改变能源结构,寻找可再生绿色能源愈来愈受到世界各国的重视.太阳能光伏发电系统的应用能够缓解能源危机、减少环境污染、减小温室效应.虽然2008年我国已成为世界第一大太阳能电池生产国,然而国内光伏市场迟迟没有启动,造成产业与市场的脱节.文章在探讨太阳能电池发电原理、转换效率和特性测试的基础上,阐述了光伏发电系统中的DCDC变换、功率点跟踪、逆变并网等应用环节.
The energy shortage and the environment pollution have been the major concern in the world,it has occupied an important position that we must find a new-clean energy. The application of solar power systems helps to alleviate the energy crisis and reduce the environment pollution. China has been the world's largest producer of solar panels but export the most,resulting in a mismatch between industry and market in the domestic. The prospect of the solar power systems in China was reviewed by elaborating the principle and feature of the solar cells,DC transform,maximum power point tracking and the grid-connected inverter.
