Abstract

This study evaluates the performance of a residential photovoltaic (PV) system located in Surabaya, Indonesia. The system, with a capacity of 4500 Wp and connected to the grid via an On-Grid inverter. Utilizing real-time data collection through EyeM4 Wi-Fi and the iSolarcloud application, the power and energy output were analyzed over daily, monthly, and annual periods. The monthly energy output showed significant seasonal variations, with the highest production recorded in December at 654.30 kWh and the lowest in February at 420.00 kWh. Daily energy outputs also varied, peaking at 25.50 kWh in March and dropping to as low as 7.20 kWh in February. The daily average energy output ranged from 14.00 kWh in February to 21.81 kWh in December. Detailed analyses of power output on typical sunny and rainy days further highlighted the impact of weather conditions on system performance. On sunny days, the system reached a daily energy output of 23.2 kWh, while on rainy days, it was significantly lower at 7 kWh. This study provides a comprehensive understanding of the PV system's operational characteristics and highlights the influence of seasonal and daily weather patterns on energy production.
