To improve the conversion efficiency of a power converter in a solar cell
module in which a solar cell module main body containing a solar cell is
integrated with a power converter for converting the output power from the
solar cell module main body, a material having small thermal conductivity
is used as a member (205) of a protective case for protecting the power
converter to be fixed to the solar cell module main body containing the
solar cell, thereby preventing easy conduction of heat from the solar cell
module main body heated to high temperatures to a power conversion circuit
(201). A material having large thermal conductivity is used as a member
(206) of a protective case for fixing the power conversion circuit (201),
thereby allowing easy radiation of heat generated in the power conversion
circuit (201).
