PURPOSE: To provide a solar battery device capable of checking the decline in power generating efficiency or shortening of battery life due to overheating by solar heat as well as enhancing the solar light energy efficiency. CONSTITUTION: A solar battery device has a flat supporting board 3, a solar battery panel 2 arranged in corrugated sheetlike mode on the upper side of this board 3, a heat collecting part 5 formed between the supporting board 3 and the solar battery panel 2 as well as a pair of end walls 6 closing both endfaces of this heat collecting part 5 and exhaust hole 7 formed on respective end walls 6 so that the solder battery panel 2 may be cooled down by the air stream formed inside the heat collecting part 5 while utilizing the exhausted heat from the heat collecting part 5. |
