The plant presents underperformance due to near shading. A string is disconnected due to a burnt connector. The structure disregards the optimal tilt angle. It is recommended to (i) substitute the damaged connector, (ii) restring the shaded and damaged modules, (iii) retrofit the mounting structure, and (iv) install an irradiation sensor on the tilted plane to compute and check the Performance Ratio. The estimated production boost expected by the retrofitting actions lies between 50 and 55%.
