Novel photovoltaic module

Abstract

The invention relates to a novel photovoltaic module which comprises a laminating piece and an alloy frame surrounding the peripheral edges of the laminating piece, wherein the alloy frame is an aluminum alloy frame and comprises the following trace elements in percentage by weight: 0.4-0.7% of silicon, less than or equal to 0.25% of iron, 0.05-0.4% of copper, 0.7-1.0% of magnesium, less than 0.2% of chromium, less than 0.1% of lead and less than 0.1% of tin. According to the invention, the novel aluminum alloy frame is adopted, so that the mechanical property of the photovoltaic module can be improved greatly, more strict outdoor use requirements are met, through testing, the photovoltaic module has higher yield strength, tensile strength and hardness, the mechanical property of the novel photovoltaic module provided by the invention is obviously superior to that of the photovoltaic module adopting a common No. 6063 aluminum alloy frame in the prior art and in addition, the weight and the production cost of the frame can be reduced.

Description

technical field [0001] The invention relates to photovoltaic power generation technology, in particular to a novel photovoltaic component. Background technique [0002] Common photovoltaic modules are provided with frames around them. The frame plays a very important role. It can not only facilitate installation, but also increase the strength of the photovoltaic module. Moreover, the frame surrounds the surrounding edges of the photovoltaic module, which can also play a good role in protection and protection. The sealing effect prolongs the service life of photovoltaic modules, and it is also convenient for transportation and installation. At present, the frame of photovoltaic modules is generally made of architectural aluminum alloy profiles, and the base material grade is 6063 / 6063T. In order to adapt to the harsh climatic conditions of the photovoltaic module installation environment, the surface of the aluminum alloy frame needs to be oxidized, and the photovoltaic mod...

AI Technical Summary

Problems solved by technology

In order to adapt to the harsh climatic conditions of the photovoltaic module installation environment, the surface of the aluminum alloy frame needs to be oxidized, and the photovoltaic module should be manufactured according to the size of the module itself, considering factors such as wind resistance and pressure and heat dissipation of the module. The current market The conventional aluminum frame for photovoltaic modules is made of 6063 material, which can achieve mechanical properties of about 200MPA, but the hardness is only 10-12HW. With the further optimization of the cost of the frame, its mechanical performance requirements are getting higher and higher. Both design and material have put forward strict requirements, and this conventional aluminum frame is becoming more and more difficult to meet more demanding application requirements
