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

近年来，光伏发电系统作为一种清洁能源，为解决全球环境等问题而受到人们的关注。在本研究中，我们收集了这39个光伏站点的设备规格、发电量等数据，并对这些数据进行评估，生成这些收集数据和评估结果的数据库，并通过互联网发布数据库。收集了39所理工学院安装的光伏系统的设备规格和发电量等数据。建立了数据评价程序，将实测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。在舞鹤工业大学设置了雪季天气状况测量系统，并收集了该点的数据。因此，光伏组件的框架造成积雪，并且很明显，通过去除积雪将获得两倍的电能。北向的数据是使用安装在和歌山技术大学的PV系统收集的，该系统可以设置可变的方向和倾斜角度。与安装在南方方向的光伏系统的电能相比，可以看出，一年的平均值为661。服务器系统在丰田工业大学建造，用于通过互联网发布。创建程序（规范化工具）以将每个学院的数据转换为统一的形式。将光伏发电系统的数据生成数据库，并通过互联网进行展示。网址是http://www.arc.ice.toyota-ct.ac.jp/pv/。本研究达到了预期的目的，并期望本研究成果能有助于光伏发电系统的进一步推广。

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.
