This investigation is concerned with the performance analysis of a con-ventional hybrid photovoltaic/thermal air heating collector. A simulation model is developed and various performance parameters are calculated for single-glass and double-glass configurations. Results are presented to show the effect of various designand operational parameters on the performance of a system. These results are useful
for designing such systems more scientifically. However, final selection of design and operational variables must be based on the cost-effectiveness of the system.
