The total amount of energy used in the world was 10,258.79(mote) in 2004, 10,820.77(mote) in 2006 and 11,294.88(mote) in 2008, which is rising by more than 3% every year, and the quantity of energy used in Korea is also making an average annual increase of 2 to 3%. This thesis aims at evaluating the energy efficiency of the photovoltaic system run in the style of tracking, according to the change in the azimuth. The research results proved that when the accumulated value of the electric power was compared, in case of 3 minutes, the generation efficiency was higher than that of fixed style by 6.4%, 8% for 5 minutes, 6.3% for 10 minutes, 9.7% for 30 minutes, and 5.8% for 60 minutes. It displayed the highest efficiency when moved at thirty-minute intervals. These results are considered to offer the basic data for the development of the future photovoltaic system in the style of contraction. |
