Photovoltaic module fixing device

Abstract

The invention relates to the field of power generation performance evaluation of photovoltaic modules, and discloses a photovoltaic module fixing device, which comprises a frame, a first sliding set and a second sliding set. The first sliding set and the second sliding set are movably arranged on the frame in the vertical direction and used for fixing the photovoltaic module. The first sliding setcomprises a first cross beam and a first sub-cross beam. The second sliding set comprises a second cross beam and a second sub-cross beam. The first cross beam and the second cross beam are movably arranged on the frame in the vertical direction, the first sub-cross beam is movably arranged on the first cross beam in the horizontal direction, and the second sub-cross beam is movably arranged on the second cross beam in the horizontal direction. According to the photovoltaic module fixing device provided in the invention, the first sliding set and the second sliding set are arranged on the frame, and the fixing position of the photovoltaic module can be adjusted by utilizing the first sliding set and the second sliding set, so that the fixing device is suitable for fixing photovoltaic modules of different specifications, and the test result deviation caused by equipment precision and human interference is greatly reduced.

Description

technical field [0001] The invention relates to the field of power generation performance evaluation of photovoltaic modules, in particular to a fixing device for photovoltaic modules. Background technique [0002] At present, the test method for the maximum power of photovoltaic modules is mainly based on the IEC61215 standard, that is, the power test is carried out under the conditions of a module temperature of 25°C and an irradiance of 1000W / m2. However, the actual outdoor environment of photovoltaic modules is quite different from the environment of laboratory standard test conditions, especially when the incident angle of light is different, the output performance of the module is significantly reduced. Because different temperatures, irradiance, spectral distribution, and different angles of incident light will affect the output power of photovoltaic modules. [0003] In order to fully evaluate the power generation of photovoltaic modules under actual conditions, it ...

Problems solved by technology

[0003] In order to fully evaluate the power generation of photovoltaic modules under actual conditions, it is necessary to fix the photovoltaic modules at different angles for measurement. The existing fixing devices are difficult to meet the photovoltaic modules of different specifications, especially during the test process of different angles, the fixed The inaccuracy of the position and the rotation angle of the fixture will cause a large deviation to the whole test result
