Investigations of relative air humidity variation dynamics in the internal environment of a concentrator photovoltaic module with a dehumidifier filled with a moisture absorbing material made of silica gel have been carried out. The device design for drying the internal air of the module to prevent moisture condensation on the Fresnel lens, photovoltaic converter and module case surfaces has been developed. Under unfavorable environmental conditions (relative air humidity up to 95%), the decrease of the module internal air relative humidity down to 25-55% at cyclic temperature change inside the module from 150С to 450С and the increase of the dew point deficit up to 10-250С have been achieved.
