The system comprising an air collector and a photovoltaic panel presented in this study allows an effective twenty-four-hour continuous supply of air exchange. The photovoltaic panel linked with the collector provides electricity to the fan that forces air circulation which, in combination with batteries, permits continuous operation. Solar energy through forced convection heats the air used in the drying process. Because the system uses solar energy (designed for this system), it is not dependent on electricity or other costly forms of energy. In the organic farm can be used for drying agricultural crops and herbs and for heating house and farm buildings.
