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 applied to deserts and tropical regions, the photovoltaic module is in accordance with tempered glass 1, a first EVA layer 2 with a UV cut off ultraviolet light 2, a cell 3, a second EVA layer 4 with a UV cut off ultraviolet light, aluminum The backplane 5, the junction box, and the aluminum frame are superimposed together to form a photovoltaic module; the aluminum backplane is composed of a first backplane film 7, a PET layer 8, an aluminum foil 9, and a second backplane film 10, such as Actually we can use the structure PA / PET / AL / PA, the thickness is 45 / 250 / 20 / 45 microns, the thickness is 45 microns, or use PET / AL / PET / fluorine, the thickness is 190 / 100 / 50 / 10 microns . The above EVA has the function of intercepting ultra-long UV ultraviolet rays and long-lasting light resistance. The thickness is between 0.4-0.5 mm. The anti-ultraviolet agent added is an ultraviolet absorber. The UV interception of ordinary EVA is 350 nm. By adding 0.3% ultraviol...

Abstract

Disclosed is a photovoltaic module applied to desert areas and tropical areas. The photovoltaic module is formed by overlaying a piece of tempered glass (1), a first ultraviolet (UV) cut-off EVA layer (2), a battery piece (3), a second ultraviolet (UV) cut-off EVA layer (4), an aluminum backboard (5), a junction box and an aluminum frame in sequence. The aluminum backboard is formed by sequentially compounding a first backboard film (7), a PET layer (8), an aluminum foil (9) and a second backboard film (10). The photovoltaic module is proper in structure and can be used not only in desert areas and tropical areas but also in various areas with severe conditions; the high-performance EVA and the aluminum backboard of a new structure are used, the performance of the module is improved, the power of the module is improved, and the service life of the module is prolonged.

Description

Technical field [0001] The invention relates to a photovoltaic module applied to 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 the standard to measure the pros and cons of power generation systems, especially in desert areas, high humidity and high heat tropical areas, 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 can easily cause component failures and affect the power generation of the entire system. Summary of the invention [0003] The purpose of the present invention is to provide a photovoltaic module with reasonable structure and suitable for use in desert and tropical regions. [0004] The te...
