The SunGold Power 450 Watt Bifacial N-Type Monocrystalline Solar Panel (model SGN-450-BDG5) is a dual glass module that makes power from both its front and rear faces. It uses 96 N-type cells (182 x 210mm), reaches 22.5% module efficiency and is UL 61730 certified by ETL and CEC listed.
It is made for installations where the back of the array is exposed to reflected light, such as flat roofs, ground brackets, vertical surfaces and poles. SunGold says the rear side can harvest up to an additional 30% energy. We sell it in packs of 2 to 20 identical panels, in steps of two.
A 2.0mm anti-reflection front glass and a 2.0mm heat-strengthened back glass sandwich the cells, held in a black anodized aluminum alloy frame. Its bifaciality is rated at 80 ±10%.
Light reflected onto the back of the module adds to its output. At a 13.5% rear-to-front irradiance ratio, the panel is rated at 499W, with 17.78A short circuit current and 16.59A at maximum power.
At standard test conditions the front side produces 450W at 30.08V and 14.97A, with a 0 to +5W tolerance. N-type cells have no LID, and SunGold says a 30-year lifespan brings 10-30% more power than conventional P-type modules.
Enhanced light trapping and optimized current collection improve both power output and reliability, including under partial shading. A design built for lower operating current also reduces hot spot loss.
The dual-sided design captures reflected light and helps clear snow, so production holds up through winter. The panel is certified for 5400 Pa of snow load and 2400 Pa of wind load, and it passed a 35mm hailstone test.
The module fits flat roofs, ground brackets, vertical surfaces and poles. Each panel has an IP68 junction box with 3 diodes and 1200mm (47.24 in) leads of 4mm² (12 AWG) wire with MC4-compatible connectors.
SunGold provides a 12-year material and workmanship warranty and a 30-year linear power warranty, with 0.40% annual degradation over 30 years.
Ground-mounted arrays. Mount on ground brackets with open space behind the panels so the rear glass can collect reflected light.
Flat roofs. Install on a flat roof, where the back of the array is exposed to reflected light.
Vertical surfaces and poles. Mount on a vertical surface or a pole, where the rear face can still collect light.
Snowy sites. Keep winter production steady, with reflected light from snow reaching the rear face.
Versus monofacial panels. A panel with an opaque backsheet only produces power from the front. This bifacial module adds rear-side energy whenever the back of the array sees reflected light, and SunGold says it can generate up to 30% more energy than conventional panels.
Versus conventional P-type modules. N-type cells don't suffer from LID. SunGold says that over 30 years this brings 10-30% more power generation than conventional P-type modules.
Versus single glass modules. Glass on both faces protects the cells front and back. SunGold says its dual glass modules offer higher durability in rough heat, cold, snow and wind.
This may be a good fit if
Up to an additional 30%, depending on how much light reaches the back. At a 13.5% rear-to-front irradiance ratio, the panel is rated at 499W.
Anywhere the back of the array is exposed to reflected light. Flat roofs, ground brackets, vertical surfaces and poles all work.
Check your controller or inverter's maximum input current. The panel's short circuit current is 16.05A at standard test conditions and 17.78A with rear-side gain.
Yes. It has an IP68-rated junction box and glass on both faces.
The SunGold Power 450 Watt Bifacial N-Type Monocrystalline Solar Panel adds rear-side energy to 22.5% efficient N-type cells, with dual glass construction and a 30-year linear power warranty.
