In this study, we have developed the solar array panel which generates electric power by utilizing the waste heat of the solar cell using thermoelectric generating modules to make a satellite bus higher power. In order to recover electric power efficiently by utilizing the waste heat of the panel, the relationship between the mounting area ratio of the thermoelectric generating modules and the temperature difference between the upper and lower surfaces of them was analyzed by simulation. The smaller the mounting area ratio was, the larger the temperature difference became, and the maximum specific power was obtained when it was 0.6%. Moreover, the specimen was produced with the configuration expected to maximize the output power, and the thermal vacuum test was carried out. As the result, specific power of 0.8W/m2 could be generated in the thermal environment simulating the on-orbit. It was demonstrated that output power could be recovered by utilizing waste heat of the solar array panel.
