Printed as "For SIL-XXX BK/BG/HC/HC+/QD, the maximum system voltage rating is 1000V for TUV/IEC and 1000V for UL." in Silfab Solar's Safety and Installation Manual for Photovoltaic Modules (MAN-SSI-13, April 29, 2026), section 9.1 Electrical Connection, the sentence that names this model's series. The manual prints the same 1000V for the UL and the TUV/IEC rating.

Printed as "RAIL MOUNTING FOR SIL QD" (table heading) with the first row printed as "Clamp Long Edge Primary 275.5 - 350.5 +3600 / -2667 +5400 / -4000" on PDF page 10 of Silfab Solar's Safety and Installation Manual for Photovoltaic Modules (MAN-SSI-13, April 29, 2026): each listed line is one printed table row or table (mounting type, mounting position, mounting zone in millimeters, design load rating and test load rating in pascals; positive values downward, negative values uplift). The manual prints both design and test loads and they differ by mounting method, so no single front or rear design load is recorded for this model. This page lists no mounting-hole row for SIL QD. Section 8.2 (PDF page 4) prints the bolt requirement for the factory mounting holes and section 8.3 (PDF page 5) permits rear flange-mounted clamps for the series lines it lists, including SIL-XXX QD.

Own one? A verified review needs a receipt and a serial number photo, and counts 19× in the owner rating.
The Evidence score uses the priorities you choose. It counts published documents, such as certificates and warranty terms, and it compares a documented figure with the best documented figure of the same kind. It does not count owner reviews, and it is not a verdict on product quality or on how many people have reviewed it. A low score can mean little is documented, or that a documented figure is below the best of its kind. Undisclosed data scores 0.
Missing for this product: Module efficiency needed; Product warranty needed; Power warranty needed; Power temperature coefficient needed; First-year degradation needed; Weight / watt needed.
Not enough comparable data for a score. None of this panel's scored inputs has a documented, sourced value yet: module efficiency, product warranty, power warranty, power temperature coefficient, first-year degradation, weight / watt.
Each input is scored against the best documented value for a solar panel, and weight per watt against the best in the panel’s own format. A documented value always earns points; an undisclosed one earns 0 and is listed as missing. Certificates and unsupported claims do not add points.
A documented panel weight and rated output are required.
