[0002] In the existing technology of the photovoltaic industry, the price of the power generation method using solar panels (also called photovoltaic panels) has reached a level that is very suitable for marketization, so most of the photovoltaic power generation components are currently made of photovoltaic panels; but The power generation efficiency of photovoltaic panels is low. For the same photovoltaic power station, the power generation system using concentrating photovoltaic modules can generate more electricity than the power generation system using photovoltaic panels. With the tightening of the supply of land resources, concentrating The power generation system of photovoltaic modules will be valued and popularized;

[0003] Concentrating photovoltaic components are commonly composed of Fresnel lenses and photovoltaic power generation components; photovoltaic power generation components include circuit boards, gallium arsenide chips and secondary concentrating mirrors; the sun's rays are concentrated once by Fresnel lenses and then passed After secondary concentrating, the secondary concentrator can reliably irradiate the gallium arsenide chip to generate electric energy, which is transmitted through the circuit board; in this structure, the distance between the Fresnel lens and the photovoltaic power generation module is a very important parameter. Traditional The test instrument is relatively large, and it is generally practical in the laboratory to achieve the most accurate distance calibration, but the cost of traditional test instruments is too high, and it is not suitable for testing in the product selection process

[0004] Concentrating photovoltaic modules need to be tested for components assembled on the production line or components in the structural design stage; the traditional test method uses the test of simulated sunlight, which can accurately calculate the accuracy, but the cost is high and complex simulation calculations are required ; However, testing CPV modules directly under sunlight conditions will increase the cost, because the volume and structure of the current two-dimensional tracking frame are relatively complicated
