Abstract
A hybrid kiln system and method for drying material, such as lumber, logs, and timber. A solar air heater uses solar radiation to heat air. The heated air is pushed into a kiln using one or more solar air heater fans. A dehumidifier is also provided to dehumidify and heat the air within the kiln. A method for determining when the solar air heater fans and the dehumidifier should be activated is also provided, and is based upon the temperature difference between the solar air heater's interior and exterior, as well as the relative humidity within the kiln.
