Disregarding the entrance and roughness effects and the 90 bend determine the pressure. Instead of heating fluid that circulates through tubing a solar hot air collector is like a parked car. Consider an air solar collector that is 1 m wide and 4 m long and has a constant spacing of 3 cm between the glass cover and the collector plate.

Consider an air solar collector that is 1 m wide and 5 m long and has a constant spacing of 3 cm between the glass cover and the collector plate. If the average temperatures of the glass cover and the collector plate are 20C and 60C. Therefore the effect of air column on pressure change is indeed negligible as assumed.

In the analysis of PVT-air collector performance the energy balance and thermal losses equations used in PVT-water collectors can also be applied. Simple pop can hot air collector.
