M2 solar wafer
Upgraded from M1 (Length 156.75, Diameter 205mm), M2 (Length 156.75, Diameter 210mm) wafer can increase the solar cell power. Without changing the size of the module, M2 could increase the module power by more than 5Wp, rapidly becoming the mainstream and maintaining the status for several years.
