The Maxion 400W panel sold by SI Solar adopts a "back contact method" where all the electrodes visible on the module surface are designed on the backside. This design allows for unobstructed sunlight capture, ensuring effective absorption of solar light. Additionally, the electrodes on the backside are arranged alternately as N-type and P-type electrodes, increasing the area of the mixed section, which facilitates smoother electron exchange and enables high power generation efficiency. The warranty is also robust, offering a 40-year guarantee for both the product and its output. The length of the warranty reflects the reliable quality and high manufacturing technology of the solar power modules. It guarantees coverage for defects in the product and any output degradation below the warranty values, as well as the necessary services for repairing or replacing defective panels.
