By accurately tracking the maximum energy point (Max-PP), which depends on the board's temperature and the irradiance conditions, maximum energy point tracking (Max-PPT) techniques are utilized as part of SC (SC) designs to increase the SC panel's output energy. To enhance the Max-PPT technique under fractional shading conditions, this paper expands the yield of the SC collection. As part of our suggested approach, a novel technique dubbed the Judgement table (JT) strategy will be utilized to track the SC collection's maximum energy under partial shade conditions, and the extensible particle swarm optimisation (Ex-PSO) algorithm will be utilized to optimise the results. The suggested approach also manages the grid fault. The results show that Ex-PSO based Max-PPT can promote SC collection to achieve the global Max-PP and assist the SC panel in producing more reliable yield management than the standard JT method.
