SunGold Power 370 Watt Monocrystalline Black Solar Panel

The SunGold Power 370 Watt Monocrystalline Black Solar Panel Gives Tiny Homes, RVs, and Rooftops Half-Cut PERC Power in a Compact Black Module

The SunGold Power 370 Watt Monocrystalline Black Solar Panel (model SG370WM) is a 120 half-cell mono PERC module with a black design. It measures 63.23 x 44.65 x 1.38 inches, weighs 41.8 lbs and reaches a 20.31% module efficiency. It is UL 61730 and CEC listed.

It works in off-grid, grid-tied and hybrid systems, from a tiny house or RV to a household or commercial roof. Its compact size makes it practical where roof space is tight. We sell it in packs of 2 to 20 identical panels, in steps of two.

SunGold Power 370 Watt Monocrystalline Black Solar Panel Features

Half-Cut PERC Cells for Shade Tolerance

The module uses 120 half-cut 182mm mono PERC cells in a 6 x 20 layout. SunGold says the half-cell wiring gives a higher shade tolerance and improves output and performance, which helps when part of an array falls into shade.

370 Watts at 20.31% Efficiency

At standard test conditions the panel produces 370W at 33.2V and 11.15A, with a ±3% production tolerance. The 20.31% module efficiency gives more output per surface area than many traditional panels.

IP68 Protection Against Dust and Water

The junction box and connectors carry an IP68 rating. They are fully protected from dust and keep working after temporary immersion in water up to 1m deep.

Rated for 5400 Pa Snow and 2400 Pa Wind

The module passed a 5400 Pa load test for heavy snow and a 2400 Pa test for wind pressure. A 3.2mm tempered glass front and an anodized aluminum alloy frame complete the build.

Grid-Tied, Off-Grid, or Hybrid

Use it to store energy in a battery bank, to cut power bills on a grid-tied home or to power a complete off-grid house. The same panel works across all three system types.

1500V Rating and 12 AWG Leads

The panel is rated for a 1500V maximum system voltage, with a 40.17V open circuit voltage, an 11.81A short circuit current and a 20A maximum series fuse rating. Its 12 AWG output cables are 1 ft long each.

Warranty Coverage Through Year 25

SunGold covers the panel with a 12-year material and workmanship warranty. Output warranties run 5 years at 95%, 10 years at 90% and 25 years at 80%.

Real-World Applications

Tiny houses. Fit useful solar wattage on a small roof with a module that is 63.23 inches long.

RVs and marine use. SunGold lists RV and marine power among its uses, and the IP68 connections stand up to wet conditions.

Household rooftops. Add panels to a grid-tied or hybrid home system to reduce power bills.

Commercial buildings. Cover a commercial roof with UL 61730 and CEC listed modules for an on-grid or hybrid system.

How It Compares to Common Alternatives

Versus full-cell panels. On a panel with full-size cells, shade on one part of the module can pull down more of its output. SunGold says the half-cut design of this panel raises shade tolerance.

Versus larger residential modules. Bigger modules produce more watts each, but they need longer roof sections and weigh more. This 41.8 lb module fits smaller roof areas.

Versus flexible panels. A flexible panel is light, while this glass and aluminum module carries a 5400 Pa snow load rating and a 25-year output warranty.

Is This Black Solar Panel the Right Fit

• Space. Each panel is 63.23 x 44.65 x 1.38 inches and 41.8 lbs.
• Voltage. Open circuit voltage is 40.17V per panel. Check your inverter or charge controller's PV voltage limit before planning series strings.
• Current. Short circuit current is 11.81A, with a 20A maximum series fuse rating.
• Appearance. It has a black design. Ask us if you need a panel with a fully black frame and backsheet.

This may be a good fit if

• You need a compact panel for a tiny house, RV or small roof
• Part of your array gets some shade
• You live where heavy snow loads are common
• You need UL 61730 and CEC listed panels

Common Questions

Is the 370W Black Panel Waterproof?

Yes. The junction box and connectors are IP68 rated, which means full dust protection and normal function after temporary immersion in water up to 1m deep.

Can It Be Used on a Grid-Tied System?

Yes. It works in grid-tied, off-grid and hybrid systems. Pair it with an inverter or charge controller made for your system type.

What Does the Half-Cut Cell Design Do?

Splitting the cells changes the wiring inside the module. SunGold says this gives the panel higher shade tolerance and better output and performance.

How Much Snow and Wind Can It Handle?

It passed load tests of 5400 Pa for snow and 2400 Pa for wind pressure.
