Abstract

The invention provides a photovoltaic module electrical performance test system and test method. The test system comprises a bracket which is provided with a plurality of metal sheets distributed in multiple rows and columns. In each row of the metal sheets, through holes running through the thickness direction of the bracket are formed in positions of the bracket corresponding to the gaps betweenevery two adjacent metal sheets. By using the photovoltaic module electrical performance test system of the invention, the problem that the working status of each or part of the cells in a photovoltaic module cannot be monitored is solved. The bracket is provided with the metal sheets distributed in multiple rows and columns, and through holes are arranged in positions of the bracket corresponding to the gaps between every two adjacent metal sheets in each row of metal sheets, so that the cells in the photovoltaic module can be placed between two adjacent metal sheets in each column, the electrical performance of each or part of the cells can be monitored easily via the through holes, and the layout design of the photovoltaic module and the abnormal analysis of the whole photovoltaic module are facilitated.

Description

technical field [0001] The invention belongs to the technical field of photovoltaics, and relates to a photovoltaic module electrical performance testing system and testing method. Background technique [0002] In order to increase the output power of photovoltaic modules, a plurality of cells need to be connected in series in a photovoltaic module. The output power of photovoltaic modules will be affected. After the cells are packaged into a photovoltaic module, the output data of the photovoltaic module becomes a set of data, which can only monitor the electrical properties (voltage, current) of the entire photovoltaic module, and cannot detect the working status of each or part of the cells, and cannot analyze The influence of the electrical performance of a single or part of the cells on the overall electrical performance of the photovoltaic module is not convenient for the layout design of the photovoltaic module and the abnormal analysis of the entire photovoltaic mod...
