High power on the 210 platform
The TSM-NEG21C.20 uses patented i-TOPCon technology on the 210 innovation platform to reach up to 725 W and 23.3% module efficiency. The standardised module size with a flagship power 35 W higher than conventional technology, and its low-voltage design with higher string power, reduce balance-of-system cost and LCOE by 2% to 6%.
Bifacial dual-glass reliability
The dual-glass structure carries a 30-year power guarantee. Non-destructive cutting and high-density packaging minimise micro-cracks, half-cut cells reduce hot-spot risk, and the module is certified against salt, ammonia, sand, PID, LID and LeTID.
High energy yield
Low-irradiation performance is validated by a third party, the temperature coefficient of Pmax is −0.29%/°C, and the back side adds 10% to 20% power gain depending on albedo.
Warranty
A 12-year product warranty and a 30-year power guarantee apply, with 1% degradation in the first year and 0.4% a year afterwards. See the product warranty for details.
