Analysis of The Impact of Wind and The Environmental Temperature on The Performance of a Rooftop Solar PV System: A Case Study of 52,2 kWp PT PLN Research and Development Center Rooftop PV Systems

This study aimed to observe the influence of weather parameters (irradiation, ambient temperature, PV module wind speed, and direction). Performance evaluation rooftop systems is carried out according IEC 61724-1:2017. The measured are solar irradiance using a pyranometer, surface temperature sensor, direction Smart Weather Sensor Lufft type WS500-UMB. analysis was performed under three different conditions: cloudy, rainy, sunny skies. In rainy conditions, highest efficiency array 16.1% – 16.69%, because environmental when it rains lowest compared cloudy conditions. skies, inverter obtained, around 97.9 98.84%, this due very high irradiation (more than 1000 W/m²), so works more optimally in average speed obtained which 3.28 m/s with same direction, namely West-Northwest, but not significant provide cooling effect PV.
