Background technique

With the development of the photovoltaic industry, the power of photovoltaic modules is becoming more and more important. Most of the frames used to install laminates now have C-direction extension plates. The width of the C-direction extension plates is generally 30mm. Even though there has been a recent There is no C-frame, but the C-free frame is basically used on the short side of the module, and the C-frame is still used on the long side. Because the C-direction extension plate on the long side has mounting holes, the C-free frame cannot be used on the long side.

In actual use, the C-direction extension plate of the frame will block the laminate and affect the power of the module. The full frame without the C-direction extension plate will bring a lot of power increase to the module, especially as the laminate is bidirectional. The extension rate continues to increase, and this design without C-direction extension boards blocking the frame has a strong practical significance. Some existing frame designs without C-direction extension boards directly cancel the C-direction extension board of the frame. They even placed the circlip notch and the installation groove horizontally. Although this reduces the obstruction of the C-direction extension plate, it also reduces the mechanical stability of the frame, which will increase the risk during future use. This kind of frame also requires the use of specific mounting brackets when installing, resulting in an increase in the cost of the mounting brackets.

With the development of the photovoltaic industry, competition in the power of photovoltaic modules has become increasingly fierce. Most of the frames used in photovoltaic modules now have C-direction extension plates. The width of the C-direction extension plates is generally mm. Even though C-free frames have appeared recently, they are basically used on the short sides of the modules, and the long sides are still the same. Use a C-frame. Because the C-direction extension plate on the long side has mounting holes, you cannot use a C-frameless one on the long side. In actual use, the C-direction extension plate of the frame will block the laminate and affect the power of the module. Calculated based on the 166-144 type components, the area of the battery blocked by the long bezel is 478.08 square centimeters, the area of the battery blocked by the C short bezel is 125.5 square centimeters, and the area of a 166 half-cell battery is approximately 136.12 square centimeters. From the calculation results The shielding area from the frame to the extension board is already very large. Therefore, a full frame without a C-direction extension plate will bring a lot of power increase to the module. Especially as the double-sided ratio of laminates continues to increase, this design without a C-direction extension plate to block the frame is more attractive. Very practical significance.

Some existing frame designs without C-direction extension plate directly cancel the C-direction extension plate of the frame, and some even place the circlip notch horizontally with the installation groove. Although this reduces the obstruction of the C-direction extension plate, it also reduces the The mechanical stability of the frame is compromised, which will increase the risk during future use. This kind of frame also requires the use of specific mounting brackets when installing, resulting in an increase in the cost of the mounting brackets.
