Solar photovoltaic systems are a pragmatic, scalable approach to capturing clean energy, providing a sustainable substitute for fossil fuel-derived electricity, and leading to a crucial element in the global shift to renewable energy. Significant emphasis is placed on improving the efficiency of solar panels. In this study, a mirror-augmented solar photovoltaic system was developed to absorb maximum solar radiation from the sun, and to lower the solar panel's temperature, a passive cooling mechanism was implemented. The modified system was incorporated with two mirrors aligned at an angle of 60° (approximately) relative to the PV panel surface on either side of the panel construction for solar radiation concentration. Fins made of aluminum were also embedded in the backside of the modified system to prevent solar panel damage due to excessive heat generation. A comparative investigation was conducted between a conventional solar photovoltaic system and a modified photovoltaic system. The typical conventional photovoltaic module produced a maximum current, voltage, and power of 1.24 A, 20.90 V, and 13.21 W, respectively, at a solar radiation level of 655.50 W/m². Under identical solar radiation, the newly designed solar panel produced a maximum current and voltage of 1.47 A and 21.5 V and a power output of 16.75 W. The modified system exhibits a 27% improvement in output power compared to the reference one.
