[0001] This application claims priority from a Chinese patent application filed with the Patent Office of the State Intellectual Property Office of China on September 21, 2023, with application number 2023225814450 and invention name “A mounting frame for photovoltaic modules”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] The invention belongs to the field of photovoltaic module installation, and in particular relates to a photovoltaic module installation frame. Background Art

[0003] The applicant continues to focus on developing packaging technology for photovoltaic modules, and has previously proposed a number of lightweight packaging materials for this purpose. As the applicant further promotes and applies it, it is found that in current photovoltaic module installation technologies, most of them use integral metal plates (such as color steel tiles, etc.) to lay and install on the building base. The installation weight is heavy and the installation cost is high, and additional grounding measures must also be set up. Although some technologies have mentioned the use of lighter installation tiles (such as resin tiles) to replace color steel tiles, they still use an integral panel installation solution, and the optimization space for installation weight and installation cost is still limited.

[0004] To this end, the applicant's R&D team, drawing on its dedicated innovative research experience in this niche field and years of accumulated industry theoretical knowledge, has optimized and improved the current state of photovoltaic module installation technology. They have previously proposed innovative technical solutions, with patent application numbers including: CN2022113402159, CN2022228653102, and CN202222865323X.
