Ekechukwu and Norton [3] conducted experiments to demonstrate a typical 40% to 50% efficiency of the conventional solar air collector.For a PV/T air collector with a ventilated system, the heat losses from PV to air flow are generally not very good, so the losses in the environment are large and the average thermal efficiency is around 10% to 20% [4]. [5] also investigated the thermal performance of single-glazed and double-glazed multipass solar air heaters. [6] found that the single-plated double-pass air heater was the most cost effective compared to the other design. [7] performed a new optimum efficiency of a hybrid PV/T system.To investigate the performance in New Delhi meteorological conditions, they investigated two types of PV modules (glass-to-plastic and glass-to-glass) and the results show that the overall performance of the hybrid thermal collector with a glass-to-glass PV module is better than with a glass-to-plastic module. [8] studied theoretical models for single- and double-ended three-pass solar air heaters. [9] studied the improvement of device performance of external recirculating multipass solar air heaters under counter flow conditions. [10] stated that they had achieved efficiencies as high as 70% of multipass solar collectors with an increased heat transfer surface. One of the most important components of a solar energy system is the collector.The various applications of the solar energy collectors have been well recorded [2].Solar collectors can be used in various areas especially for drying, floor heating, and solar desalination and so on Conventional solar air collectors have inherent disadvantages in lower thermal efficiency.
