Product Overview
TWMNH 66HD is Tongwei Solar's 66-cell commercial N-type TOPCon bifacial module — 600–620W — targeting C&I rooftop and small ground mount projects where competitive per-module cost matters more than the marginal efficiency gain of the 700W+ power class. At 600–620W, this panel suits 50–500 module commercial orders where price-per-watt competitiveness is the primary selection criterion.
Tongwei Solar's vertically-integrated cell supply keeps TWMNH 66HD cost-competitive against equivalent 600W-class modules from brands that source cells externally. N-type TOPCon cells deliver lower degradation and higher energy yield over the panel's service life than mono PERC equivalents at the same stated wattage.
OmniSol sources TWMNH 66HD for C&I and distributor buyers seeking Tier-1 N-type TOPCon performance at competitive pricing. Coordinated with H1Z2Z2-K cable, 1500 V DC protection packages and aluminium or steel roof racking to suit the installation rooftop type.
Applications
