Heavy soiling was observed. Cables with bite marks and missing string labelling were found. Several modules show presence of PID. It is recommended to (i) increase cleaning cycles, (ii) replace the cleaning equipment used, (iii) install anti-PID box to mitigate damages from PID, (iv) re-sort PID affected modules, and (v) install a weather station or at least an irradiation sensor on the module plane to quantify and monitor the performance ratio. The estimated production boost expected by the retrofitting actions is expected to be around 35% to 40%.
