Abstract

The present invention provides a photovoltaic module electrical performance testing system and testing method. The testing system includes: a bracket, and a plurality of metal sheets are arranged on the bracket. The plurality of metal sheets are distributed in multiple rows and columns, and the metal sheets in each row are In the sheet, through holes penetrating through the thickness direction of the bracket are respectively formed at positions corresponding to the distance between two adjacent metal sheets on the bracket. According to the photovoltaic module electrical performance testing system of the present invention, the problem that it is impossible to monitor the working status of each or part of the cells in the photovoltaic module is solved. Through-holes are respectively provided on the support in the sheet at positions corresponding to the intervals between two adjacent metal sheets, and the cells in the photovoltaic module can be placed between two adjacent metal sheets in each column, and the through-holes are convenient Monitoring the electrical properties of each or part of the cells facilitates layout design of photovoltaic modules and abnormal analysis of the entire photovoltaic module.

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...
