HiDM5 All-Black High Density Mono Perc Module

The CS1Y-400MS Solar Panel features HiDM5, High Density Shingle Cells. These mono-PERC cells allow for higher energy yield because they maximize the light absorption area, providing a high module efficiency of 19.9%. The higher efficiency allows for 37% more system capacity on a single roof top or ground array. It is so efficient that you can get up to 19% more power in partial shading conditions. The Shingle cell is a full square and there are no ribbons or cell gaps, providing an completely homogenous appearance. All of these features make the CS1Y-400MS an ideal module for solar installations needing performance and superior aesthetics.
