Optimization of PV Modules through Tilt Angle in Different Cities Of Punjab, Pakistan

This paper evaluates the optimum tilt angle and available direct solar radiation on the inclined surface of the PV Cell in the province Punjab, Pakistan. This mathematical model provides the maximization of Solar Radiation impinging on the Solar collectors. Instead of Solar Collector placed at latitude angle with the help of parameters like Slope, orientation, azimuth surface angle and the hour angle of the PV Cell. The variation in the Solar Radiation on the PV Cell from Latitude to Tilt angle is represented graphically. Considered cities of Punjab are Lahore, Mangla, Sialkot, Gujranwala and Multan. This study reveals that as latitude angle varies from 33° to 28°, intensity increases approximately from 0.3KWh/m ² to 0.6KWh/m ² which will result in increased output power. Seasonal optimum angle has also been listed. Optimization of tilt angle has the highest effect on solar irradiance in winter season when day is shorter hence more light is required to fulfill our requirement.
