Problems solved by technology

[0002] Photovoltaic modules are the core components of photovoltaic power generation applications, and high-performance, high-quality photovoltaic modules are a measure of the pros and cons of power generation systems, especially in desert areas, tropical areas with high humidity and high heat, good heat dissipation and water vapor Permeability can better reflect the power output and life span of the components. It is understood that the aluminum alloy backplane has poor insulation performance and is easy to absorb and accumulate electrostatic charges, which is likely to cause component failure and affect the power generation of the entire system

Embodiment Construction

[0016] A photovoltaic module used in deserts and tropical regions, the photovoltaic module is based on tempered glass 1, a first EVA layer 2 that cuts off UV ultraviolet rays, a battery sheet 3, a second EVA layer 4 that cuts off UV ultraviolet rays, aluminum The backplane 5, the junction box, and the aluminum frame are stacked together in order to form a photovoltaic module; the aluminum backplane is composed of the first backplane film 7, the PET layer 8, the aluminum foil 9, and the second backplane film 10 in sequence, such as Actually we can use structure PA / PET / AL / PA with thickness of 45 / 250 / 20 / 45 microns and thickness of 45 microns, or use PET / AL / PET / fluorine with thickness of 190 / 100 / 50 / 10 microns . The above-mentioned EVA has the function of cutting off ultra-long UV ultraviolet rays and long-term light resistance, and its thickness is between 0.4-0.5 millimeters. The anti-ultraviolet agent it adds is an ultraviolet absorber. The above EVA can achieve the function of...

Abstract

The invention discloses a photovoltaic module applied to desert areas and tropical areas. The photovoltaic module is formed by overlaying a piece of tempered glass, a first UV cut-off EVA layer, a battery piece, a second UV cut-off EVA layer, an aluminum backboard, a junction box and an aluminum frame in sequence. According to the photovoltaic module, the aluminum backboard is formed by sequentially compounding a first backboard film, a PET layer, an aluminum foil and a second backboard film. The photovoltaic module is reasonable in structure and can be used not only in the desert areas and the tropical areas but also in various areas with severe conditions, the high-performance EVA layers and the aluminum backboard of a novel structure are used, the performance of the photovoltaic module is improved, the power of the photovoltaic module is improved, and the service life of the photovoltaic module is prolonged.

Description

technical field [0001] The invention relates to a photovoltaic module used in deserts and tropical regions. Background technique [0002] Photovoltaic modules are the core components of photovoltaic power generation applications, and high-performance, high-quality photovoltaic modules are a measure of the pros and cons of power generation systems, especially in desert areas, tropical areas with high humidity and high heat, good heat dissipation and water vapor Permeability can better reflect the power output and lifespan of the components. It is understood that the aluminum alloy backplane has poor insulation performance and is easy to absorb and accumulate electrostatic charges, which is likely to cause component failure and affect the power generation of the entire system. Contents of the invention [0003] The object of the present invention is to provide a photovoltaic module suitable for use in desert and tropical regions with reasonable structure. [0004] Technical...
