Abstract

During 2017 and 2018, performance ratio (PR) of the 60 kWp photovoltaic-system (PVS) was evaluated at the north location of Mexico City. The solar irradiation was detected using the thermopile-pyranometer installed in a plane of array (POA) of PV panels. The average daily generated energy for 2017 was 261.65 kWh/day, with a PR of 80.1%. For 2018, the generated energy was 254.79 kWh/day with a PR of 76.6%. The day-time average PV module temperature during 2017 was 34.8 ºC and 35.6 ºC for 2018. Soiling effect in PV-array was also measured, indicating about a 20 % of PR reduction.
