PROBLEM TO BE SOLVED: To provide a generation accumulation system using temperature difference between solar-heated portion and underground portion radiating heat, which can efficiently generate power even in a cloudy weather or the like, efficiently store the generated power and supply the power to an electric load. SOLUTION: The generation accumulation system includes an upper plate 2 having a portion for receiving and storing solar heat on its upper surface and a heat insulating material portion arranged so as to surround the portion to be increased in temperature, a lower plate 6 to be cooled either by radiating heat into ground or into water through a heat conductive pipe 7 with a drilling blade 8 at the lower tip end or by leading the low temperature in the ground or in the water with the heat conductive pipe 7 to be decreased in temperature, a power generator 20 having a Peltier element 5 held between the upper plate 2 and the lower plate 6, a battery device 30 including a sodium sulfur cell, an electric power load 40 including a lighting lamp or the like, and a switching device 50 connected among the power generator 20, the battery device 30 and the electric power load 40, supplying the electric power generated by the power generator 20 to the electric power load 40 for driving thereof or to the battery device 30 for charging thereof or supplying the electric power discharged from the battery device 30 to the electric power load 40 for driving thereof.
