Performance evaluation and optimization of albedo and tilt angle for solar photovoltaic system

This research focuses on the UN sustainable development goal (SDG)7 i.e., affordable and clean energy. As per goal 7, renewable energy sources are the cleanest sources and will help to reach net zero emissions. Performance of solar photovoltaic (PV) systems is analysed using PVsyst and Response Surface Methodology (RSM) for composite climatic conditions. Two critical parameters i.e., tilt angle and albedo are investigated. Specific production increases as albedo and tilt angle increase. Optimum tilt angle is 25 & DEG; at 0.54 albedo with a maximum specific production of 1643.3 kWh/kWp/year. Payback period is 5.8 years, the return of investment (ROI) is at 469.2% and the levelized cost of energy (LCOE) is 2.298 (sic)/kWh. During its lifetime, the system reduces 3470.5 tCO2 carbon emission compared to the conventional plant. Therefore, installing such a system will dramatically reduce CO2 emissions, encourage environmental sustainability and enhance the number of claimed carbon credits.

Automated summary
