Device for reducing pressure of photovoltaic module in rain and snow weather

Abstract

The invention discloses a device for reducing the pressure of photovoltaic modules in rain and snow weather. The device comprises a glass plate, a solar cell panel and a back plate, wherein the solarcell panel is arranged between the back plate and the glass plate which is located over the solar cell panel, and the back plate is located under the solar cell panel; drainage grooves are formed in the side, away from the solar cell panel, of the glass plate, the drainage grooves include the horizontal drainage grooves and the vertical drainage grooves, the horizontal drainage grooves are formedin the side, away from the solar cell panel, of the glass plate in a mutually parallel mode, and the vertical drainage grooves are formed in the side, away from the solar cell panel, of the glass plate in a mutually parallel mode and are perpendicular to the horizontal drainage grooves; drain holes are formed in the intersection positions of the horizontal drainage grooves and the vertical drainage grooves, the drain holes run through the glass plate, the solar cell panel and the back plate, and the drain holes are formed in the gaps between batteries in the solar cell panel. Rainwater flows into the drain holes through the horizontal drainage grooves and the vertical drainage grooves and flows out, so that the huge shock damage of the rainwater on the photovoltaic modules is avoided.

Description

technical field [0001] The invention relates to photovoltaic components, in particular to equipment for reducing the pressure of photovoltaic components in rainy and snowy weather. 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 problem that the photovoltai...
