SMD performance of solar patches

Due to the use of monocrystalline silicon solar cells, the photoelectric conversion efficiency of monocrystalline silicon solar cells has been about 22%, and the highest is 24%, which is the highest photoelectric conversion efficiency among all kinds of solar cells. Since monocrystalline silicon is generally packaged with tempered glass and waterproof resin, it is rugged and durable, and most manufacturers generally provide 25 years of quality assurance.
SMT is surface mount technology (short for Surface Mounted Technology) and is currently the most popular technology and process in the electronics assembly industry. Surface Mount Technology (SMT) is called surface mount or surface mount technology. It is a type of leadless or short lead surface mount component (referred to as SMC/SMD, Chinese called chip component) mounted on the surface of a printed circuit board (PCB) or other substrate surface. Circuit mounting technology for soldering and assembly by reflow or dip soldering.
Advantages of solar patch after SMT processing: high assembly density, small size and light weight of electronic products, and the size and weight of patch components are only about 1/10 of that of conventional plug-in components. After SMT is generally used, the volume of electronic products is reduced by 40. %~60%, weight loss 60%~80%. High reliability and strong anti-vibration ability. The solder joint defect rate is low. High frequency characteristics are good. Reduced electromagnetic and radio frequency interference. Easy to automate and increase productivity. Reduce costs by 30% to 50%. Save materials, energy, equipment , manpower, time, etc. Laminated structure
1. The role of tempered glass is to protect the main body of power generation.
2. EVA is used to bond fixed tempered glass and power generation main body.
3. The main function of the main power generation is power generation. The solar patch uses monocrystalline silicon solar cells, which has high photoelectric conversion efficiency and is suitable for power generation in outdoor sunlight.
4 Back plate function: sealed, insulated and waterproof. Part of the role of ultra-white cloth tempered glass: according to the size of the solar patch to cut it.
EVA: It becomes a transparent gel after melting at a high temperature, and the cell sheet and the glass are bonded, and the TPT is bonded to the cell sheet and the glass, and is a packaging material.
TPT: It is waterproof, dustproof, insulated and protective.
Aluminum alloy frame: The aluminum alloy frame acts as a protective glass for easy installation.
Junction box: The junction box acts as an electrical connection to extract the energy from the solar panel. The diode in the junction box is called a bypass diode to prevent hot spots.
