Dear Customer

Sub: Engineering Change Notice for change in Risun’s solar cell Size

As part of our “continuous improvement (CI)” program and following the feedback from our esteemed customers, we have adopted a change in the cell size. The cell size will changed to 156.75*156.75mm±0.25mm from 156*156mm±0.5mm.

We have confirmed, at the Risun and some customers side, the power of module can improve 1.0-2.0Watt using the 156.75*156.75mm cells compared to the 156*156mm cells at the same efficiency level. We expect this would benefit the customers in improving the module power. And the module side just need make a little adjustment.

For example, the Risun module size is 1636*992*35mm, please see below chart:
