Abstract

This study evaluates the actual performance of a 4.5 kWp on-grid photovoltaic (PV) system installed on a residential building in Surabaya, Indonesia. The research aims to assess the system’s energy output under real operating conditions, providing valuable insights for residential PV deployment. Data was collected through an online monitoring system, recording daily energy production ranging from 8.0 kWh to 24.0 kWh. The total annual energy generation was approximately 6,122 kWh, resulting in an average specific energy yield of 1,360 kWh/kWp. The findings indicate that residential rooftop PV installations in Indonesia can contribute significantly to household energy needs and carbon reduction efforts. This study highlights the practical implications for homeowners, policymakers, and researchers, offering empirical data to support policy development and investment decisions in solar energy.
