As the worldwide demand for solar renewable energy continues to rise, researchers have consistently aimed to create cost-effective, high-efficiency solar cells. They are aware that elevated panel temperatures can result in reduced conversion efficiency and diminished long-term dependability, presenting a familiar challenge within the photovoltaics industry. This project is divided into two main studies related to Photovoltaic (PV) panels overheating and cooling systems. The first study focused on investigating the effect of high ambient temperature on the efficiency of solar system, theoretically using MATLAB, AutoCAD and Helioscope, and computationally using PVsyst Software. Results showed that up to 11% of energy output is being lost due to temperature, and error of 2% was detected between theoretical and computational simulations. The findings indicate that computational modeling can be a trustworthy means of forecasting the performance of solar cells and solar systems. Following the identification of the problem, an already modeled and designed radiative cooling system using a combination of nano and micro structuring glass was simulated using PVsyst and theoretical equations to illustrate the output energy of the residential solar system, where results showed that adding one more panel can result in energy output higher by 2% than using the proposed cooling system.
