Within the scope develop of energetical sustainable model for fruits drying, the original air solar heater was constructed. This air solar heater was constructed as half-concentric. The cheap and accessible materials were used. During 2006, the energy parameter research of this collector was done. Air enthalpy on exit from collector represent energy effect. Submitted utilization factor upwards of 0.5 with maximum solar radiation. Utilization factor is according with concept of adhibition. Calculated data was used for defining surface of flat solar collector. Comparing production cost between half-concentric and flat solar collector, defined effective of half-concentric solar collector. It can be concluded that the half-concentric solar collector are very welcome with aspect of relationship price and heat power.
