The PV plant, from the safety perspective, presents a defective module attachment. Although a few hotspots, likely due to heavy pollution were spotted (IR), the sample of PV modules did not reveal major cracks or isolated parts. It is recommended to (i) increase cleaning frequency (removing hard-soiling), (ii) cable fixing with UV protection (iii) continuous cleaning of the inverter-fan filters and (iv) 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 lies between 10% and 13%.
No weather station has been installed and the Performance Ratio is not tracked.
