本实验室光伏系统装机容量为70.38kWp，并网作为实验室照明系统。为实现远程监控和电能管理，设计了远程监控系统和设备监控网络平台，通过串口通信转换器将软硬件设备集成，通过RS485通信接口和以太网将相关发电数据反馈到服务器，供后台人员进行数据管理。此外，太阳的仰角和方位角与发电模块角度的关系被检查。研究结果表明，水平单轴太阳跟踪模块不能优化年发电量。在设置太阳跟踪光伏组件时，除了考虑东西角外，还要考虑南北倾角，即角度补偿斜式单轴太阳跟踪系统，使组件表面与所在区域的太阳入射角更加匹配，四季发电均优于固定组件。
The installed capacity of the photovoltaic system in this laboratory is 70.38kWp, which is connected to the grid as the laboratory lighting system. To achieve remote monitoring and electric energy management, a remote monitoring system and equipment monitoring network platform is designed, where the software and hardware equipment are integrated by a serial communication converter, and the RS485 communication interface and Ethernet feedback the related power generation data to the server for backend personnel to manage data. In addition, the relationship of the elevation angle and azimuth of the sun to the power generation module angle is examined. The findings show that the horizontal one-axis sun tracking module cannot optimize the annual electricity generation. In addition to the east-west angle, the south-north tilt angle shall be considered when setting the sun tracking PV module, i.e. the angle-compensating oblique one-axis sun tracking system, in order that the module surface further matches the solar angle incidence of the region, and electricity generation of all seasons is better than the fixed module.
