Description

Method for real-time monitoring of large-scale solar module health, system and computer program for performing the method This document relates to a method for real-time monitoring of the health of large-scale solar modules, a system for performing the same, and a computer program. In accordance with the government's energy transition policy, the construction and operation of new and renewable energy generation facilities are proceeding on a large scale. Figure 1 is a diagram illustrating an example of a conventional photovoltaic power generation system. Referring to Figure 1, large-scale solar power plants are operated with hundreds of thousands of solar modules installed on a large site. While the integrity of solar modules is very important in large-scale solar power plants, checking the integrity of hundreds of thousands of solar modules one by one is practically impossible due to the high time and cost involved. Although the health of solar modules can be verified through thermal imaging using some drones, their utility is limited due to issues such as the drones' short operating time (about 20 minutes), cost, and restricted flight zones. Furthermore, existing remote monitoring systems for individual solar modules face significant limitations in their application to large-scale solar power systems due to cost issues. Figure 1 is a diagram illustrating an example of a conventional photovoltaic power generation system. FIG. 2 is a block diagram illustrating a large-scale solar module health real-time monitoring system according to one embodiment of the present document.
