FULL SCREEN FRAME FOR PHOTOVOLTAIC MODULE AND MOUNTING METHOD FOR IT

Description

Technical Field

[0001] The present invention relates to a photovoltaic module, and in particular to a full-screen photovoltaic module frame and an assembly process therefor.Background Art

[0002] At present, the installed capacity of large-scale ground power stations and distributed power stations is increasing year by year, and there are also various types and installation methods of their installed components. Large-scale ground power stations and most of the distributed power stations use traditional frame schemes to meet the requirement of the service life of the installed components of 25 years or more under water vapor and load tests by means of technologies such as anodic oxidation, hot-dip galvanizing and anti-UV. Large-scale ground (photovoltaic) power stations generally have a large installed capacity, a large installation workload, and complex operation and maintenance. In contrast, distributed (photovoltaic) power stations are favored by household customers, and distributed power stations impose more stringent requirements on the components than conventional components in terms of appearance and electrical performance. CN 207117556 U discloses a full-screen photovoltaic module frame.

[0003] The earlier application of Chinese patent "New-type photovoltaic module frame" with the application no. 202021962623.4 filed by the applicant discloses a photovoltaic module frame ("referring to FIGS. 3 and 4" for the prior art in the background art is wrong, and should be "referring to FIGS. 1 and 2"), which solves the problems of conventional photovoltaic modules that it is impossible to observe overflowing silica gel during assembly due to the presence of side A and that it is easy to form dirt on an inner side of the side A to cover a photovoltaic module panel, which affects power generation and even causes hot spots. However, such a frame structure is still complicated. In addition to high difficulty in machining process and high production cost, the user needs to apply silica gel in both a bottom face silica gel overflow groove and a side face silica gel overflow groove of the frame during assembly. Since silica gel is applied in multiple positions directly, the assembly process has many procedures and is low in efficiency and high in machining cost. In addition, since silica gel is applied in multiple positions, in addition to difficult control on the silica gel application control amount, multiple silica gel overflow groove cavities are provided correspondingly, resulting in large silica gel overflow amount, so that the effect of controlling the silica gel overflow amount still needs to be improved.Summary of the Invention Technical Problems

[0004] The objective of the present invention is to provide a full-screen photovoltaic module frame and an assembly process therefor, which solves the problems in the background art and achieves a simpler frame structure, lowered machining difficulty and a reduced production cost.
