A 440-watt all-black N-type panel for home and off-grid arrays
SunGoldPower's SGN-440-SW5 is a 440-watt all-black monofacial panel with 108 half-cut N-type monocrystalline cells and 22.5% module efficiency. Half-cell wiring gives it higher shade tolerance, and N-type cells have no light-induced degradation.
It works in off-grid, on-grid and hybrid systems, has an IP68 junction box and connectors, and passed 5400 Pa snow and 2400 Pa wind load tests. SunGoldPower lists UL 61730 certification by ETL, a 12-year product warranty and a 30-year linear power warranty.
N-type cells, 22.5% efficient
108 half-cut N-type M10 cells reach 22.5% module efficiency, and N-type cells have no light-induced degradation.
- Half-cell layout for higher shade tolerance
- Pmax temperature coefficient -0.29%/K
IP68 junction box and connectors
The junction box and connectors are fully dust-protected and keep working after temporary immersion in water up to 1 m deep.
Snow and wind protection
Passed load tests of 5400 Pa for heavy snow and 2400 Pa for wind pressure, and works from -40°F to 185°F.
- 3.2 mm tempered, anti-reflective glass
- Anodized aluminum frame
For off-grid, on-grid and hybrid systems
