Because the Earth detours path of the solar to result in the transformation along with the season to differ from, performs of geographical position difference the north and south hemisphere, will have time and the angle throughout the year the different sunshine in the different position. Therefore establishment of angle and the direction the solar energy board will affect the whole electricity generation potency. Therefore this research is according to the related meteorological data, then the use program in various positions and outside the angle computation simulation's way, strengthens the mobile in addition north Taiwan the Namhkok different latitude and different (elevation 1000 meter, 2000 meter, 3000 meters) gauges on the spot highly meets the card gross data and the measured data accuracy. But substitutes for the artificial empirical rule judgment way, discovers position and the angle the best solar energy board installment by the time, provides the manufacturer installment to establish the material effectively to raise the economic efficiency.
