| Abstract: |
| Photovoltaic/Thermal (PV/T) solar system is considered one of the most promising technologies which offers harness and production of both electric and thermal energy. In the current study an energetic analysis is carried out to compare between four different configurations which are: single pass single glazed (PV/T-I), single pass double glazed with air gap (PV/T-II), single pass double glazed with argon gap (PV/T-III) and double pass double glazed (PV/T-IV) hybrid photovoltaic/Thermal air collector systems. A 3 dimensional numerical model is simulated and validated with both numerical and experimental results coming from literature. The numerical simulations have been accomplished to investigate energetic performance with a detailed thermal and electrical study taking in account an inlet coolant temperature the same as the ambient temperature for an air flow rate of 0.025 kg/s of a typical day in August from 9:00 to 17:00 under the ambient conditions of Beijing, China. The results show that the single pass single glazed configuration has the highest electrical efficiency, whereas the double pass configuration has the highest thermal and energy efficiencies among the proposed configurations. The average daily energy efficiencies are 53.14%, 75.92%, 77.63% and 82.19% for (PV/T-I), (PV/T-II), (PV/T-III) and (PV/T-IV) configurations, respectively. |
