Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic components, and in particular to a device for testing a photovoltaic component hail test. Background Art

[0002] Photovoltaic modules generally refer to solar cell modules. Since the output voltage of single-chip solar cells is relatively low, and the electrodes of unpackaged cells are easily detached due to environmental influences, a certain number of single-chip cells must be sealed into solar cell modules in series and parallel to avoid corrosion of the cell electrodes and interconnections. In addition, packaging also prevents cell breakage and facilitates outdoor installation. The quality of packaging determines the service life and reliability of solar cell modules.

[0003] In the prior art, there is a photovoltaic module anti-hail impact test device, whose structure includes at least two transmission wheels and a conveyor belt tensioned on each of the transmission wheels, at least one of the transmission wheels is connected to a power mechanism so as to be driven to rotate by the power mechanism to drive the conveyor belt to move, and a mounting seat for loading an ice ball simulating hail is provided on the conveyor belt. The photovoltaic module anti-hail impact test device has a first working state in which the ice ball is loaded and a second working state after the ice ball is ejected. When the first working state is switched to the second working state, the ice ball is separated from the mounting seat and has a speed The ice ball is launched forward to the photovoltaic module to be tested, and the speed of the ice ball is stable and easy to adjust. Although the speed of the ice ball in the photovoltaic module anti-hail impact test device is stable and easy to adjust, the photovoltaic module is fixed on the mounting frame, which is troublesome to disassemble the photovoltaic module. In addition, since the photovoltaic module has no protective equipment, the hail will rebound and splash under the action of the photovoltaic module after contacting the photovoltaic module. The splashed hail debris may cause harm to the testers, and the scattered hail debris will form water stains on the ground if it is not cleaned up. If it is cleaned up, it will be inconvenient to clean up because the hail debris splashes and scatters.
