A state of art review on the performance of transpired solar collector

Utilisation of solar radiation to heat air for various purposes, e.g. ventilation, pre heat, process air heat and their applications has attracted more and more interests. Wide range of applications adapted for different climates and in different building types ranging from houses to large industrial buildings. Recently in many European countries, USA and Canada this concept developed rapidly. Transpired solar collectors (TSCs) have proven reliable for various applications, e.g. heating spaces, providing warm ventilation air, supplying domestic hot water in summer, etc. Present paper consists of introduction to various types of TSCs, working principle, research literature for performance and modelling. Further various models have also been discussed and compared. The literature has shown that the most critical factors affecting TSC efficiency are wind velocity, flow rate, porosity, absorptivity and porosity.
