Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component frames, and specifically to a composite material frame for a photovoltaic component. Background Art

[0002] A photovoltaic panel is a device that converts sunlight into electrical energy through the photoelectric effect. It consists of multiple photovoltaic cells. When sunlight strikes a photovoltaic cell, it generates photons, which are absorbed, generating an electric charge and current. This process is also known as photoelectric conversion. The output power of a photovoltaic panel is affected by factors such as the intensity, angle, and spectrum of the sunlight. To increase output power, photovoltaic panels are generally made of high-efficiency materials such as monocrystalline or polycrystalline silicon, and may use anti-reflective coatings and other coatings to improve light absorption.

[0003] Aluminum frames dominate the current photovoltaic module market, accounting for a significant portion of the cost. PV frames are a crucial component of the module, serving as the structural framework for securing and sealing the module. They significantly impact module lifespan and require high weather resistance. PV frames can be categorized by material as aluminum alloy, steel, or composite materials. Aluminum alloy frames are the most widely used, with a penetration rate exceeding 95%. Their price accounts for approximately 10% of the total cost of a photovoltaic module, second only to the solar cell.

[0004] Composite photovoltaic frames offer four major advantages over aluminum alloy frames: low material cost, excellent weather resistance, insulation, and a lightweight and aesthetically pleasing design. Composite frames are currently 20%-25% cheaper than aluminum frames, with further price reductions expected. Composite frames are resistant to heat, humidity, acids, alkalis, and salt spray, making them widely suitable for harsh environments. Composite frame systems require no grounding, reducing system-side PID risk and improving system operation and maintenance safety. Composite frames are lightweight and aesthetically pleasing, making them easy to transport and install.

[0005] The current photovoltaic panel frames have poor firmness, and the installation method is too simple. They have poor wind resistance, are prone to loosening and falling off, and have no protective function.

[0006] Therefore, improvements are made to address the above problems. Utility Model Content
