Thermal and Electrical Performance Optimization of Semi-Transparent Photovoltaic Rooftop Systems Using Natural Cooling Strategy
摘要
A model has been established for fluid-driven semi-transparent photovoltaic modules (wherein the fluid media is taken as water) integrated with the building. Performance analysis for the same has been taken up by integrating the system with various techniques to minimize the dependency on artificial means of cooling. Analytical expressions for room, solar cell, floor, and water temperatures, along with solar cell efficiency, electrical power, and daylight savings have been written. A relative analysis has been computed for the system with and without the fluid flow, and has been noted that room temperature drops by 17.57 °C. The effects of packing factor, velocity, air changes, and relative humidity on the performance of the proposed configuration have also been examined. It has been found that electrical efficiency can be increased by 7.20% by just adjusting the packing factor. The numerical computations have been carried out for the hot climatic conditions of New Delhi, India.
