太阳能路灯的优化设计与经济性评估 摘要 全球的能源短缺、环境污染、气候变暖等问题正日益困扰着人类社会，“寻求绿色替代能源，实现可持续发展”已成为世界各国面临的共同课题。太阳能光伏发电不排放CO2和SO2等污染性的气体，也没有常规发电的噪音、固体废物和其他污染，是当前最重要的可再生能源技术之一。随着太阳能发电技术的不断发展，太阳能路灯以环保、节能、安全等优势成为城市道路照明行业的新宠，市场潜力巨大。在不同地区，诸如城市或乡村，对太阳能路灯照明密度的要求不同，本论文主要通过研究太阳能路灯及太阳能电池的工作原理，太阳能电池的基本特性及太阳能路灯系统的优化设计，根据不同的要求主要从实用性和经济性方面考虑选择出适合本地区需求的相应容量的太阳能光伏电池以及太阳能光伏电池配置。 关键词：太阳能路灯,光伏电池,优化设计 Study on the Selection of photovoltaic cells solar street lamp Abstract Global energy shortages, environmental pollution, climate warming and other issues are increasingly troubled by the human society, to find the green alternative sources of energy and achieve sustainable development has become a common task facing all countries in the world. Solar PV does not emit CO2 and SO2, there is no noise of conventional power generation, solid waste and other pollution, is the most important renewable energy technologies. With the continuous development of solar power technology, solar energy street lamp to environmental protection, energy saving, security and other benefits to become the new darling of city road lighting industry, the market has great potential. In different regions, such as cities or rural areas, the density of solar street lighting requirements are different, this thesis by studying the solar lights and solar cell works, the basic characteristics of solar cells. According to different requirements, mainly from the practical and economic considerations demand for choice in the region suitable for the corresponding capacity of solar photovoltaic cells and solar photovoltaic cells configured.
