SunGold Power 450 Watt Bifacial N-Type Monocrystalline Solar Panels | 32 Panels

SunGold Power 450 Watt Bifacial N-Type Solar Panels Bring 22.5% Efficiency and Rear-Side Gain to Every Panel on the Pallet

This listing includes 32 SunGold Power SGN-450-BDG5 panels, each rated 450W at standard test conditions. Each one is an N-type monocrystalline, bifacial dual glass module with 96 cells in a black anodized aluminum frame, and the model is UL 61730 certified by ETL and CEC Listed.

The bifacial design lets the back of the panel produce power from reflected light, which SunGold says can add up to 30% more energy. SunGold lists flat roofs, ground brackets, vertical surfaces and poles as mounting options. It suits homeowners and installers planning a mid-size to large array who want every panel to match.

SunGold Power 450 Watt Bifacial N-Type Solar Panels Features

450W With 22.5% Module Efficiency

Each panel is rated 450W at STC and 338W at NMOT, with 22.5% module efficiency. You get more output from a limited mounting area.

Extra Output From Rear-Side Light

With a bifaciality of 80±10%, the back glass adds output when light reflects onto it. At a 13.5% rear-to-front irradiance ratio, SunGold rates the panel at 499W.

N-Type Cells Without LID

N-type solar cells have no light-induced degradation by nature, according to SunGold, and they hold up well in low light. SunGold says a 30-year lifespan brings 10-30% more generation than conventional P-type modules.

16 Busbars and Half-Cut Cell Layout

SunGold says the 16-busbar cells improve efficiency, durability and microcrack resistance. Half-cut cells reduce shading effects and shorten current paths, and every module passes a 100% triple EL test to reduce hidden cracks.

Dual Glass Construction

The front is 2.0mm glass with an anti-reflection coating, and the back is 2.0mm heat strengthened glass. The module is certified for 5400 Pa of snow load and 2400 Pa of wind load, and it passed a 35mm hailstone test.

Steady Output in Heat

A -0.29%/K power temperature coefficient and a 43±2℃ nominal operating temperature limit losses on hot days. SunGold also designed the panel for lower operating current to cut hot spot loss.

Waterproof Connections

The IP68 junction box has 3 diodes, and each panel comes with 12 AWG (UL) leads, 1200mm long including the MC4-compatible connector.

Real-World Applications

Ground mounts. Elevated ground brackets let reflected light reach the rear glass.

Flat roofs. Mount the panels on tilted racks so light can reach the back glass.

Vertical and pole mounts. SunGold lists vertical surfaces and poles among the supported setups.

Snow country. SunGold says the dual-sided design keeps producing in snow, and the panels are built for heavy snow and strong wind.

Practical Comparison

SunGold Power 450 Watt Bifacial Panels Versus P-Type Panels

SunGold rates its N-type panels at an 80% bifaciality factor, compared with 70% for P-type panels. Over a 30-year lifespan, it puts the extra generation of N-type modules at 10-30%.

SunGold Power 450 Watt Bifacial Panels Versus Single-Sided Panels

Single-sided panels only use the light that hits the front. These dual glass modules also use reflected light at the back, so the gain depends on how much reflected light reaches the back of the array.

SunGold Power 450 Watt Bifacial Panels Versus Mixing Panel Models

Buying 32 identical SGN-450-BDG5 modules at once keeps every string on the same electrical ratings.

Buyer Guidance

Plan Your Strings

Each panel has a 35.03V open-circuit voltage and a 16.05A short-circuit current at STC. Short-circuit current rises to 17.78A with rear-side gain at a 13.5% irradiance ratio. Size strings within your inverter or charge controller limits, the 1500V maximum system voltage and the 30A maximum fuse rating.

Handling the Panels

Each module weighs 53.35 lbs and measures 69.37 x 44.65 x 1.38 inches. Plan for a freight delivery and help with unloading for a 32-panel order.

This May Be A Good Fit If

• You want N-type bifacial panels with 22.5% efficiency
• Your site has reflected light behind the array
• You need 32 matching panels for one project
• You need UL 61730 certified, CEC Listed modules

Common Questions

Are the Panels Waterproof?

Yes. SunGold confirms they are waterproof, and the junction box and connectors are IP68 rated for protection against dust and water.

How Many Panels Do I Get?

32 panels, each rated 450W.

What Does the Warranty Cover?

SunGold gives a 12-year material and workmanship warranty and a 30-year linear power warranty, with 0.40% annual degradation and 87.4% of rated power guaranteed at year 30.

Are These Single Glass or Dual Glass Panels?

Dual glass. Both the front and back are 2.0mm glass.
