Each adjusting supporting assembly comprises a fixing stand column, a connection plate and an adjusting assembly, wherein the connection plate is fixedly connected to the fixing stand column, the photovoltaic assembly supporting frame is hinged to the connection plate, the end of the adjusting assembly is fixedly connected with the photovoltaic assembly supporting frame, the adjusting assembly is provided with a plurality of inclination adjusting hole positions, the connection plate is provided with a bolt piece, and the bolt piece can be inserted into the inclination adjusting hole positions in a matched mode so as to adjust the angle of inclination of the photovoltaic module supporting frame; the I-V test device is connected with an irradiation meter, and the irradiation meter is arranged on the photovoltaic module supporting frame. By means of the auxiliary photovoltaic module I-V curve test device, solar irradiation collection of different mounting regions and at multiple kinds of mounting angles of inclination can be achieved, a photovoltaic module can be mounted at different angles of inclination conveniently to obtain the best irradiation, and research and improvement of the whole photovoltaic system performance are facilitated.

Description

technical field [0001] The invention relates to an auxiliary device for testing the I-V curve of a photovoltaic module with an adjustable inclination angle, and belongs to the technical field of solar energy. Background technique [0002] At present, the solar energy industry, as a low-carbon renewable energy source, is booming around the world, and the installation volume in various countries is increasing year by year. The installation of photovoltaic systems needs to be designed according to the environmental conditions of different countries, regions, and sites. The optimum installation inclination angle can usually be designed according to the latitude and radiation conditions of different regions. Therefore, photovoltaic modules in different regions are usually installed with different inclination angles. The I-V curve of photovoltaic modules is usually measured in an indoor test room, which will be very different from the actual comprehensive solar radiation environme...
