Solar array power gets drastically reduced under shading conditions. To handle this cause, a novel geometrical reconfiguration (NGR) based on the physical relocation of solar modules is proposed. Geometrical reconfiguration helps in recognizing an accurate location of points and lines on the given plane, leading to the formation of different geometrical shapes by solar modules prone to shadings. A symmetrical solar array is thoroughly investigated under two realistic shadings, namely S1 and S2. Various performance metrics like global power (GP), degraded power (DP), fill factor (FF), and power enhancement ratio (PER) under various shadings are calculated to study the efficacy of the proposed technique. The performance of the novel geometrical reconfiguration (NGR) is measured against the benchmark total cross-tied (TCT) and sudoku reconfiguration (SR). The suggested NGR brings down the degraded power by 9.96% and 11.15% over TCT and SR under S1 shading. The results show that the proposed geometrical reconfiguration outperforms as compared to other considered reconfiguration schemes and has caused higher shade dispersion on solar arrays during shading conditions.

摘要

Solar array power gets drastically reduced under shading conditions. To handle this cause, a novel geometrical reconfiguration (NGR) based on the physical relocation of solar modules is proposed. Geometrical reconfiguration helps in recognizing an accurate location of points and lines on the given plane, leading to the formation of different geometrical shapes by solar modules prone to shadings. A symmetrical solar array is thoroughly investigated under two realistic shadings, namely S1 and S2. Various performance metrics like global power (GP), degraded power (DP), fill factor (FF), and power enhancement ratio (PER) under various shadings are calculated to study the efficacy of the proposed technique. The performance of the novel geometrical reconfiguration (NGR) is measured against the benchmark total cross-tied (TCT) and sudoku reconfiguration (SR). The suggested NGR brings down the degraded power by 9.96% and 11.15% over TCT and SR under S1 shading. The results show that the proposed geometrical reconfiguration outperforms as compared to other considered reconfiguration schemes and has caused higher shade dispersion on solar arrays during shading conditions.
