Establishment and Case Analysis of a Photovoltaic Cloud Management System

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.
