Silfab SIL-440 QD DCA2 440W Domestic-Content Solar Panel

Silfab SIL-440 QD DCA2 440W Module

The Silfab SIL-440 QD DCA2 is the domestic-content build of Silfab's 440-watt N-type residential module, made in the USA with USA-sourced encapsulant and backsheet. It carries the same next-generation 108 half-cut N-type cells and 22.6% efficiency as the standard SIL-440 QD, with a clean triple-black design, but its added domestic-content sourcing is built for projects pursuing domestic content adders.

By sourcing the encapsulant and backsheet in the USA on top of domestic module assembly, the DCA2 variant can contribute to domestic content bonus eligibility for qualifying installations. It keeps the same compact 67.8 in format, Stäubli MC4 connectors, 1000 V maximum system voltage, and 25-year product warranty, so installers gain domestic-content sourcing without changing their residential system design.
