Popis: Performance ratio (PR) of 60 kWp photovoltaic system (PVS) were measured considering the soiling effect in the interval of December 2019 to January 2020. Towards final week of December 2019, the PVS started showing a poor PR due to the natural soiling in a photovoltaic-array, but due to rainfall at mid-January 2020, the PR was recuperated. The average PR for January was 71.1%, but the cleaned PV-array by the rainfall showed an about 14 points of increment in energy generation from 63.3 to 77.3 %. Also, it is discussed the average generated energy during 2019 which was 267.8 kWh/day and in 2020, it was 273.3 kWh/day, with the corresponding PR of 76.7% and 76.8%, respectively.
