摘要
第三代太阳能电池采用聚光光伏技术(Concentrated Photovoltaic,CPV),与第一代晶硅电池和第二代薄膜电池相比,它具有更高的转换效率、更好的耐高温性能和更环保的资源利用优势。太阳能跟踪系统是CPV技术关键的组成部分,它的追日效果直接影响着CPV电池的转换效率。本文从太阳能跟踪系统的原理出发,针对CPV系统追日的高精度要求和国内光伏产业的0EM市场现况,着重阐述了一种以SIMAT1C S7-1200 PLC为核心的低成本解决方案在具体项目中的应用。
The third generation solar cell applies Concentrated Photovoltaic （or CPV） technology with higher conversion efficiency, better high temperature resistant performance and more environmentally friendly utilization of resources, as compared with the first and the second generation ones. Solar tracking system plays a vital role in CPV-tech. Considering the demand of high accuracy for solar tracker and the existing circumstance of PV OEM market in China, this paper mainly states the principle of solar tracking system and puts forward a typical low cost solution based on SIMATIC ST-1200 PLC.
