Evaluation of Photovoltaic Performance by 40kW PV System Installed at National College of Technology and their Database

近年来，为了解决全球环境等问题，光伏发电作为一种清洁能源受到了广泛关注。在39所理工学院安装了40kW光伏系统。在本研究中，我们收集了39个光伏站点的设备规格和发电量等数据，对这些数据进行了评估，生成了这些收集的数据和评估结果的数据库，并将数据库通过互联网发布。收集了39所理工学院安装的光伏发电系统的设备规格和发电量等数据。编制了数据评估程序，将测量数据与太阳辐射模拟值进行了比较，并对各学院的发电量进行了比较。在清水理工学院安装了雪季天气状况测量系统，并采集了该点的数据。因此，光伏组件的框架会造成积雪，很明显，通过消除积雪可以获得两倍的电能。北向的数据采集使用安装在和歌山理工学院的光伏系统，该系统可以设置可变的方向和倾斜角度。与南向安装的光伏系统的电能相比，一年的平均值为661。服务器系统是丰田理工学院建设的，用于在互联网上发布。创建了将每个学院的数据转换为统一格式的程序(标准化工具)。光伏系统的数据以数据库的形式产生，并通过互联网进行展示。网址为http://www.arc.ice.toyota-ct.ac.jp/pv/.研究目的可以达到，希望本研究成果能够为光伏系统的进一步推广做出贡献。

Recently photovoltaic power (PV) system which is a clean energy source has been attracted attention in order to solve global environment problems and so on. 40kW PV systems were installed in 39 Colleges of Technology. In this research, we collect the data in theses 39 PV sites such as the equipment specification and generated electric energy, evaluate these data, produce the database of these collecting data and the evaluation result, and publish the database by the Internet. Data, such as the equipment specification and generated electric energy by PV system installed in 39 Colleges of Technology, was collected. The evaluation program of data was created and we compared the measured data with the values simulated from solar radiation and compared the generated electric energy of each College. The weather condition measurement system was installed in Maizuru College of Technology with snow season, and the data in this point was collected. Consequently, the frame of a PV module causes snow coverage, and it became clear that twice electric energy will be obtained by removing snow coverage. The data in north direction was collected using the PV system installed at Wakayama College of Technology which can be set variable direction and tilted angle. As compared with the electric energy of PV system installed in south direction, it became clear that the average value in a year was 661 The server system was built in Toyota College of Technology for publication with the Internet. The program (normalizing tool) was created to transfer the data of each College into the unified form. The data of PV system was produced as database, which is exhibited by the Internet.
