We have showed the possibility of solar drying in Slovenia. Glass panels, photovoltaic panels for producing hot water, and photovoltaic cells for electricity generation were compared. Data collected on the duration and solar radiation were calculated, and the average conditions provided by the provider panels. The free energy of solar radiation, depending on the season and location in Slovenia, which could take advantage of the floor area of the chamber, was compared to the energy required for drying of 50 mm thick beech (Fagus sylvatica L.). Possibilities to cover energy demands to use solar energy are only 3.5 %; therefore, in present conditions still not acceptable.
