Wafers are produced from slicing a silicon ingot into individual wafers. In this process, the ingot is first ground down to the desired diameter, typically 200 mm. Next, four slices of the ingot are sawn off resulting in a pseudo-square ingot with 156 mm side length.
At present, polycrystalline silicon photovoltaic cells play a dominant role in silicon-based solar cells because of its advantages such as relatively simple preparation process and relatively low cost. Slicing is the first mechanical processing procedure for battery cells, the quality of sawn surface affects the cost of subsequent processes

The solar rail splice is a component that connects two aluminum rails. This component is mainly used for components where the length of the guide rail is not enough, and two or more guide rails need to be spliced together. As an industry standard, the longest length of the aluminum rails produced by the factory cannot exceed 7 meters. Excessively long rails will bring heavy work
