PERFORMANCE RATIO MAXIMIZATION FOR GRID-TIED SOLAR PV SYSTEMS

The performance of solar PV systems are highly dependent on the irradiance profile (amount of sunlight), soiling, shading, temperature effects, module technology, inverter selection, string orientation etc. A major task for a PV system designer is to choose optimum technology and design the PV system to maximize the performance ratio (PR). For instance, up to 10% shade in a PV system may reduce the power output to 50%. Therefore, a major task in this area is to optimize system design in commercial and domestic setting. Our work includes using state-of-the-art softwares incorporating practical experience from over 800 kWp of solar installation at LUMS.
