Mathematical Modelling of a System for Solar PV Efficiency Improvement Using Compressed Air for Panel Cleaning and Cooling

The efficiency of solar photovoltaic (PV) panels is greatly reduced by panel soiling and high temperatures. A mechanism for eliminating both these sources inefficiencies presented integrating PV generation with a compressed air system. High-pressure can be stored used to blow over the surface panels, removing present dust cooling increasing output power. full-system mathematical model proposed system presented, comprised storage, temperature, cleaning, power generation. Simulation results indicate benefit employing cleaning panels. For fixed volume air, it advantageous early in day if soiled or when radiation most abundant highest achievable flow rate clean. These strategies have been shown achieve greatest energy captures single panel. When comparing compression gain from two-week period, an ROI 23.8 determined. has potential eliminate requirement additional manual
