Solar with green and wide distribution advantages , along with dwindling fossil fuel reserves , while the traditional green energy sources, hydropower has a huge impact on the ecological environment , nuclear power because of the existence of a variety of factors the risk of leakage , the distribution of the wind more uneven and regional differences apparent solar energy become a national development and research focus. Photovoltaics is the field of solar energy applications important research direction . However, due to the existence of low energy density of solar illumination time is not continuous, light intensity unstable shortcomings, but the cost of producing photovoltaic cells is still high , thereby increasing photovoltaic solar energy conversion efficiency of the system , reduce the construction cost of power generation system is a solar power generation required to solve two major contradictions . Concentrating photovoltaic (Concentrated Photovoltaic, CPV) system through the use of a large area condenser sunlight concentrated in photocell , photovoltaic cells per unit area increased power generation , greatly reducing the cost of photovoltaic power generation systems account for a large share of the light battery usage. The same time as the use of solar tracking systems , CPV systems throughout the day with a more stable output components of the system but because of CPV , including the solar tracker , condenser , light cells and other parts of its system structure is relatively complex , the efficiency of the various components of the system different effects , the matching of each component made ??certain design requirements. Thesis developed a photovoltaic CPV systems test system includes automatic solar tracking platform and photocell voltammetry (Ⅰ - Ⅴ) characteristics measurement system , capable of CPV systems more comprehensive and long-term tests for the various components of CPV systems match provide the basis for design . Research on solar concentrating photovoltaic power generation system tracking system control strategy analysis, optimization biaxial solar tracking system is designed to ensure that the advanced nature of the test system , and applicability . And the preparation of LabVIEW graphical programming language based on the development of test software, control Keithley 2602A SourceMeter photocell for CPV systems are tested to achieve a natural light photocell Ⅰ - Ⅴ characteristics of fast acquisition , display, analysis , storage, etc. function . The experiment proved that the system has good stability and scalability.
