It is built for residential and commercial PV arrays that need a modern ~440 W module with Stäubli MC4 connectors and a 1,500 VDC maximum system voltage.\u003c\/p\u003e\n\u003cp\u003eTOPCon (tunnel oxide passivated contact) is an N-type cell technology. Bifacial double-glass construction lets the rear glass collect reflected light; actual rear-side energy depends on mounting height, tilt, and ground reflectance. Module efficiency at STC is 22.53% on the manufacturer datasheet.\u003c\/p\u003e\n\u003cp\u003eThis listing is for a \u003cstrong\u003esingle\u003c\/strong\u003e SPDG440-N108M10 module.
