Abstract

Previous work carried out at LABSOLAR in Brazil has established that thin-film amorphous silicon (a-Si) is a good choice of PV technology for operation in warm and sunny climates. Meanwhile, PETROBRAS, the Brazilian oil company, is looking at different renewable energy technologies to spread its energy mix and energy product portfolio. The company, recognizing the present and future role that photovoltaics will play in the world energy scenario, has established links with LABSOLAR to receive training and build knowledge on PV. This paper describes the design and installation of the so far largest PV system in the country: a 45.5 kWp grid-connected thin-film system, comprising six sub-systems using PV modules from four different a-Si manufacturers, one cadmium telluride (CdTe) and one copper indium gallium diselenide (CIGS) manufacturer. The fully monitored PV installation will compare the long-term output performance of state-of-the-art thin-film technologies, looking at annual energy yields and performance ratios at both module and system levels.

巴西国家石油公司45.5 kWp并网光伏系统:在巴西运行的六种薄膜组件类型的比较研究

先前在巴西LABSOLAR进行的工作已经确定，薄膜非晶硅(a- si)是光伏技术在温暖和阳光充足的气候下运行的良好选择。与此同时，巴西国家石油公司(PETROBRAS)正在研究不同的可再生能源技术，以扩展其能源结构和能源产品组合。公司认识到目前和未来光伏将在世界能源格局中扮演的角色，与LABSOLAR建立了联系，接受培训并积累光伏知识。本文描述了迄今为止该国最大的光伏系统的设计和安装:一个45.5 kWp并网薄膜系统，包括六个子系统，使用来自四家不同的a- si制造商，一家碲化镉(CdTe)和一家铜铟镓二硒化(CIGS)制造商的光伏模块。全面监控的光伏装置将比较最先进的薄膜技术的长期输出性能，查看模块和系统级别的年能源产量和性能比。
