Recently, solar light power generation is widely extended by support policy to regeneration energy. However generation efficiency is decreased when solar module maintain higher than certain point temperature. Therefore, it is need to maintenance under certain point temperature. An method of solving this problem, this paperis developed geothermal exchanger for efficiency improvement of solar cell module. Geothermal exchanger consistedof heat absorber of solar cell module and heat conductor and radiator. Heat of solar cell module is radiated in the earth by geothermal exchanger. An a result, geothermal exchanger is increased generation amount of solar cell moduleand experiment result showed costs to about 36% increment of generation power.
