Device for preventing shaking of backboards in photovoltaic assembly

Abstract

The invention discloses a device for preventing shaking of backboards in a photovoltaic assembly. The device for preventing the shaking of the backboards in a photovoltaic assembly comprises a solar battery panel, a lower backboard, an upper backboard and fixed plates. The solar battery panel is arranged between the lower backboard and the upper backboard. The upper backboard is arranged right over the solar battery panel. The lower backboard is arranged right under the solar battery panel. The upper backboard and the lower backboard are connected through first bolts in a vertical direction. The upper backboard and the lower backboard are fixedly connected to a third fixed member in a horizontal direction. Under forces coming from a vertical direction and a horizontal direction, the upperbackboard and the lower backboard are not easy to move slightly, which prevents cracks or fractures of the solar battery panel which are caused by moving the backboards and guarantees normal operationof the photovoltaic assembly.

Description

technical field [0001] The invention relates to a photovoltaic module, in particular to a device for avoiding shaking of a backboard in a photovoltaic module. Background technique [0002] Photovoltaic modules (commonly known as solar panels) are composed of solar cells or solar cells of different specifications cut by a laser cutting machine or a steel wire cutting machine. Since the current and voltage of a single solar cell are very small, then we first connect them in series to obtain a high voltage, and then connect them in parallel to obtain a high current, and then output it through a diode (to prevent current return). And package them on a stainless steel, aluminum or other non-metal frame, install the upper backplane on the top and the lower backplane on the back, fill with nitrogen, and seal. The whole is called a module, that is, a photovoltaic module or a solar cell module. [0003] In the prior art, there is a slight movement of the backplane of the photovolta...

AI Technical Summary

Problems solved by technology

[0004] The invention solves the problem in the prior art that the backplane of the photovoltaic module will move slightly during use, causing cracks or ruptures in the cells of the solar panel, which affects the normal operation of the photovoltaic module, and provides a method to avoid the backplane of the photovoltaic module. The device that shakes the panel can prevent the upper and lower backplanes of the photovoltaic module from moving slightly, avoid cracks or ruptures in the cells of the solar panel, and ensure the normal operation of the photovoltaic module
