[0006] Although this document discloses the test method for the power generation of photovoltaic modules, the test process only relies on the inverter to test and obtain data. The accuracy of the test data is poor, and it is difficult to compare or compare the test data.
It is impossible to obtain the status of the standard power generation efficiency under the current power generation environment, but only to obtain the currently tested data of the component board
However, it is impossible to conduct comprehensive evaluation tests on newly installed power stations or power stations installed and operated for several years

The invention provides a testing method for detection and calibration of an outdoor high-precision photovoltaic power station. A standard assembly plate is mounted in the to-be-tested photovoltaic power station, so that a standard photovoltaic power generation efficiency testing assembly and a to-be-tested photovoltaic power station assembly of the photovoltaic power generation station maintain the same illumination condition and the same temperature condition; a host of test equipment analyses the current state of the photovoltaic power station. For the power station which is mounted and operates for several years, actual power generation data can be compared and tested, and the actual power generation data in the actual mounting environment are obtained. The standard photovoltaic power generation efficiency testing assembly is pre-configured before testing and mounted in the testing environment, so that the standard photovoltaic power generation efficiency testing assembly and the tested photovoltaic power generation efficiency testing assembly have the same using environment, simultaneous and synchronous testing is conducted, and comprehensive evaluation testing is realized.
Description
Technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a test method for outdoor high-precision photovoltaic power station detection and calibration. Background technique [0002] At present, the photovoltaic market is huge, and photovoltaic technology is developing rapidly. It is often possible to develop photovoltaic power generation products with better quality and perfect performance. The power generation capacity of photovoltaic power generation products is one of the important indicators to determine the performance of photovoltaic power generation products. An important factor in whether the actual power station can be recognized or not. At present, the power generation efficiency of photovoltaic power generation products can be obtained by testing the power generation capacity of photovoltaic power generation products. For example, for the power test and power generation test of photovoltaic power generation products,...
