Analysis of energy, exergy, environmental and economics (4E) on photovoltaic-thermal collector system

In this paper, a novel thermal absorber based photovoltaic-thermal system is presented. The attached at the rear surface of photovoltaic, and water re-circulated to extract heat. outdoor experimentations are performed Pune, India (18.7611? N, 73.5572?) on clear sky day, temperatures, temperature, radiation flow rate measured analyse techno-economical performance different operating conditions. temperature photovoltaic module plummeted from 54.65?C 47.9?C with incorporation flipside cooling ranging 0.03 0.06 kg per seconds. result shows an average enhancement 4.2 % in electrical power output system. maximum efficiencies were 47.82 9.88 %, respectively, exergy efficiency was found range 9.85-14.30%. Based experimental evaluation, uncertainty analysis performed. results revealed that annual CO2 mitigation for 225.46 464.8 annual, while simple payback periods 4.53 years 3.03 years, respectively. offers efficient estimate features systems energy-exergy, environmental cost-benefit standpoint.
