The REC TwinPeak Series is a new solar panel with an innovative layout and different cell technology that increases the power available from a polysilicon cell up to 275 Wp. In combination, the technology inherent in the new REC TwinPeak Series delivers an increase of 10 Wp per panel compared to REC’s current REC Peak Eenrgy Series panel. The most obvious difference in the REC TwinPeak Series compared to a standard solar panel is the cell design. The new panel is based on standard sized cells of 156 x 156 mm that have been cut into two equally sized pieces (156 x 78 mm), to give 120 half-cut cells.The panel is then split into two ‘twin’ sections of 60 cells each,
connected in series, in three strings. The two sections are then
connected in parallel in the center to give a panel of 120 cells (fig. 1).
This new design and layout is supplemented by a collection of other
enablers:
