Abstract

The aim of this work is the evaluation of the data obtained from experimental PV solar system performance. 500 Wp PV system is installed on the roof of Faculty of Electrical Engineering and Information Technology of Slovak University of Technology in Bratislava, Slovakia. In addition the obtained results are compared with the PVGIS simulation. A brief summary of components and construction parts of photovoltaic system, description of the individual elements forming the system (photovoltaic modules, the inverters and the equipment of measuring and data processing) is given. The electrical parameters of PV system and irradiation intensity which allows the calculation of efficiency during the operation of PV grid connected systems are measured. Moreover, the measurements of weather and environmental factors like temperature and other (humidity and air pressure, wind speed) have been continuously done. Detailed analyses under different operating conditions, performing some monthly and daily analysis and comparing them with solar radiation database from climatologic data homogenized for Europe (PVGIS) were performed.

小型光伏电站预测与生产

这项工作的目的是评估从实验光伏太阳能系统性能获得的数据。500wp光伏系统安装在斯洛伐克布拉迪斯拉发斯洛伐克理工大学电气工程与信息技术学院的屋顶上。并将所得结果与PVGIS仿真结果进行了比较。简要概述了光伏系统的组成和构成部件，并对构成该系统的各个元件(光伏组件、逆变器、测量和数据处理设备)进行了描述。测量了光伏并网系统运行过程中光伏系统的电气参数和辐照强度，从而计算光伏并网系统的效率。此外，天气和环境因素，如温度和其他(湿度和气压，风速)的测量一直在持续进行。在不同的运行条件下进行了详细的分析，进行了月度和每日的分析，并与欧洲气候数据均质化(PVGIS)的太阳辐射数据库进行了比较。
