SEG Solar 440W Solar Panel 108 Cell All-Black Bifacial SEG-440-BTD-BG-T3 Domestic Content Wholesale 36 Panels per Pallet

The SEG Solar YUKON N Series SEG-440-BTD-BG is a 440W all-black bifacial solar panel built on N-type monocrystalline cell technology, engineered for residential, commercial, and utility installations that demand high output in a clean, low-profile aesthetic.

Note: This panel qualifies as Domestic Content under current IRS guidance, making it eligible for the bonus adder under IRS Notice 2023-29. Buyers should confirm project-specific eligibility with their tax advisor, as qualification depends on total system composition and applicable Treasury rules.

Key specifications

• Warranty: 30-year product and workmanship warranty; 30-year linear power output warranty (87.4% at year 30)

High output without compromising aesthetics

Rooftop installations increasingly require both performance and appearance. The SEG-440-BTD-BG uses a fully black frame, black backsheet, and black cell layout to deliver a uniform, low-contrast look that satisfies HOA requirements and architectural standards — while still producing 440W per panel at STC. Installers don't have to choose between curb appeal and capacity.

N-type cell advantage in real-world conditions

N-type monocrystalline cells carry a lower degradation rate than conventional P-type cells, with first-year attenuation of just 1.0% and annual degradation capped at 0.4% thereafter — reaching 87.4% output retention at year 30. The -0.30%/°C Pmax temperature coefficient means the panel holds output better on hot summer days when rooftop temperatures climb well above 77°F (25°C). Combined with an operating range of -40°F to 185°F (-40°C to 85°C), the YUKON N Series is suited for climates ranging from desert southwest to cold northern rooftops.

Bifacial gain: more output, same footprint

The bifacial design captures albedo light reflected from rooftops, ground, or adjacent surfaces through the rear glass, adding effective yield without increasing panel count or racking area. With 80±10% bifaciality, rear-side contribution depends on installation conditions — ground-mount and elevated roof-mount applications with light-colored or reflective surfaces see the highest gains. The dual 2.0 mm semi-tempered glass construction and IP68-rated junction box protect bifacial performance over the full 30-year warranty period.

Application scenarios

• Residential rooftop: All-black aesthetic meets HOA and architectural requirements; high efficiency reduces panel count on space-constrained roofs
• Commercial rooftop: 1500V DC system voltage enables longer string runs, reducing combiner and wiring costs
• Ground-mount utility and farm: Bifacial gain is maximized on elevated racking over light-colored ground — gravel, sand, or snow-prone areas
• ITC bonus adder projects: Domestic Content qualification supports bonus ITC credit stacking for eligible commercial and utility projects
• Coastal and agricultural environments: Salt mist (IEC 61701) and ammonia resistance (IEC 62716) certifications support marine-adjacent and near-livestock installations

System compatibility

The SEG-440-BTD-BG operates at up to 1500V DC and is compatible with all major string inverter platforms rated for that system voltage, including Enphase, SolarEdge, SMA, Fronius, Growatt, and Solaredge. The MC4 connector standard ensures plug-and-play compatibility with virtually all balance-of-system wiring. Panels can be wired in series for higher voltage strings or in parallel to maintain voltage at the inverter's MPP range. The 12 AWG UL-listed PV wire ships in portrait orientation at 400 mm ( ) / 200 mm (−) or landscape at 1200 mm on both leads; custom lengths are available. This panel ships 36 units per pallet, easing procurement math for residential and light commercial projects.

Why choose the SEG Solar SEG-440-BTD-BG?

The SEG-440-BTD-BG is one of the few all-black bifacial N-type panels that ships as Domestic Content-qualified, making it directly relevant to commercial and utility buyers pursuing the IRS bonus adder. SEG Solar backs it with a 30-year product and 30-year linear power warranty — among the longest in the industry — from a Houston, Texas-based company with over 6 GW shipped globally. For installers who need high efficiency, clean aesthetics, and bankable warranty terms in a single SKU, this panel covers all three.
