The duration of street light illumination on solarpowered public street lighting is often short-lived (decreased Tlol) due to exposure to near shading (loss irradiance) of 8.89% in residential complexes. Therefore, optimization of PV panels and battery components through PVsyst software simulation analysis is required. The simulation results after optimization showed that the PV array obtained 205 wp and a battery capacity of 62 ah (2 days of autonomy), resulting in a decrease in Tlol of 765 hours. While the Performance Ratio (PR) is 67.6%, there is an increase of 7.7%, and the sulfuric ratio is 93.6%, there is an increase in the energy supplied to users by 12.74% or 33.36 kWh.
