Among new renewable energy, photovoltaic power generation is being developed by many researchers as an energy source without any kind of pollution. In this research, Ⅲ-Ⅴ Multi-junction Chips whose generating efficiency is high are used and by adding the optical/photovoltaic system- dual axis- tracking HCPV(High Concentration Photovoltaic) system- to the established generating system in the experiment increasing energy integration by focusing sunlight into one point, we compared the difference in generation capacity in accordance with the concave mirror's area and the difference in generation rate in accordance with the chip size of the III-V GaAs compound solar receiver. The result shows that generated energy is proportional to the area of 1st parabolic reflector. That is, when the area increases, at the same rate power generation increased, and when we observed the generation changes by the chip size of the solar receiver using the same 1st parabolic reflector, the power generation also increased proportionally to the chip size of the solar receiver.
