Description
技术领域technical field
本发明涉及能源设备技术领域，具体来说，涉及一种提升光伏发电转化率的装置及太阳光高反射涂料。The invention relates to the technical field of energy equipment, in particular to a device for improving the conversion rate of photovoltaic power generation and a high-reflective coating for sunlight.
背景技术Background technique
国家能源局发布“太阳能发电十二五规划”，建立太阳能提升发电综合技术支持体系，建立完善太阳能发电产业体系。太阳能电力提供清洁的可再生能源，有效缓解日趋严重的能源紧张，生态环境恶化和雾霾天气，目前光伏发电技术已日趋成熟并广泛推广和应用。为此发明了聚光光伏发电技术：如菲涅耳透镜聚焦，图透镜聚焦，金属光反射膜等等，这些方案中总有一部分太阳光损失而发电效率低或因户外环境原因造成聚焦镜污染破损，金属腐蚀结构复杂，转换率低等原因使用受到限制。The National Energy Administration issued the "Twelfth Five-Year Plan for Solar Power Generation" to establish a comprehensive technical support system for solar power generation upgrades, and to establish and improve the solar power generation industry system. Solar power provides clean and renewable energy, effectively alleviating the increasingly serious energy shortage, ecological environment deterioration and smog weather. At present, photovoltaic power generation technology has become increasingly mature and widely promoted and applied. For this reason, concentrating photovoltaic power generation technology was invented: such as Fresnel lens focusing, image lens focusing, metal light reflective film, etc. In these solutions, there is always a part of sunlight loss and low power generation efficiency or pollution of the focusing mirror due to outdoor environment. Damage, metal corrosion, complex structure, low conversion rate and other reasons are limited in use.
另外，目前现有技术中提高发电效率的途径主要是通过跟踪装置跟踪太阳光的位置，使光伏发电装置与太阳光尽量垂直，从而使太阳光尽量与光伏板垂直，例如申请号为200910218708.3的中国专利公开的一种太阳光跟踪装置，其在一定程度上可以提高发电的效率，但是还是有一部分太阳光透过光伏板而没有被有效利用起来，而且光伏板周围漫反射的光也同样被浪费了，因此发电的效率有限；因此上述现有技术提升发电效率有限，并且其因为结构复杂，因此工程应用价值不高。In addition, the way to improve power generation efficiency in the existing technology is mainly to track the position of the sunlight through the tracking device, so that the photovoltaic power generation device and the sunlight are as vertical as possible, so that the sunlight is as perpendicular as possible to the photovoltaic panel, for example, the Chinese patent application number 200910218708.3 A solar tracking device disclosed in the patent can improve the efficiency of power generation to a certain extent, but part of the sunlight still passes through the photovoltaic panels and is not effectively utilized, and the diffusely reflected light around the photovoltaic panels is also wasted Therefore, the efficiency of power generation is limited; therefore, the above-mentioned existing technology has limited improvement in power generation efficiency, and because of its complex structure, its engineering application value is not high.
