This paper provides energy, exergy and environmental analyses for hybrid photovoltaic-thermal based combined heat and power system. Grid-connected configuration was used to increase the system reliability when satisfying the load. A series of battery and hot-water storages were applied for saving the excess of electricity and heat, respectively. Technical evaluations were conducted based on experimental data using real-time measurement devices throughout 31 days and estimated annual energy generation. The results showed that the average of electrical energy, thermal energy, electrical exergy and thermal exergy generations in a day were 0.34 kWh/m(2), 0.60 kWh/m(2), 0.34 kWh/m(2), and 0.01 kWh/m(2) per day, respectively with the solar irradiation average of 3.25 kWh/m(2) per day. The maximum efficiencies of electrical energy, thermal energy, electrical exergy, and thermal exergy generations were 16.73%, 51.09%, 16.73% and 0.85%, respectively. This research also found the electrical and thermal energy efficiencies of the system were degraded by 1.20% and 1.89% per year, respectively. The system reduced the carbon dioxide emission annually by 855.1 kg per year or approximately 26.75% lower than a conventional separated system. (C) 2020 Elsevier Ltd. All rights reserved.
