EAGLE HM HALF CELL MODULE WHITE PAPER
What are EAGLE Half Cell modules (HM)? The EAGLE HM module uses half-cut cell technology and half cell layout to improve power and performance. This technology delivers more power from the same number of cells and has enhanced reliability compared to full cell modules. The half-cut cell is a standard size solar cell (158.75mm x 158.75mm) that has been cut into two equal pieces (Fig. 1). Each half cell module is split into two sections of 60 half-cut cells that are connected in series.
