SunGold Power 450 Watt Monocrystalline Solar Panel

The SunGold Power 450 Watt Monocrystalline Solar Panel Gives Cabins, Campers, and Off-Grid Systems a Mid-Size PERC Module With IP68 Protection

The SunGold Power 450 Watt Monocrystalline Solar Panel (model SG450WM) is a mid-size PERC module with 120 monocrystalline cells and a 20.79% module efficiency. It measures 75.16 x 44.65 x 1.38 inches, weighs 54 lbs and is UL 61730 and CEC listed.

It is designed for off-grid systems that power a cabin, camper, RV or boat, and for industrial and professional installations. We sell it in packs of 2, 4, 6, 8, 10, 12, 14, 16, 18 or 20 identical panels, which makes it easy to build matched strings.

SunGold Power 450 Watt Monocrystalline Solar Panel Features

450 Watts From 120 PERC Cells

The module uses 120 PERC monocrystalline cells (182 x 91mm, or 7.2 x 3.6 in) in a 6 x 20 layout. At standard test conditions it produces 450W at 34.2V and 13.16A, with a ±3% production tolerance.

20.79% Efficiency With Good Weak-Light Output

Grade A cells reach a 20.79% module efficiency, and the panel is rated for excellent performance in weak light. That helps on cloudy days and early or late in the day.

IP68 Junction Box for Wet Locations

An IP68-rated junction box and IP68 connectors keep water out, which makes the panel suitable for marine applications. The waterproof design lets you use it in all weather conditions.

Twin Wall Anodized Aluminum Frame

The scratch-resistant anodized aluminum frame has a twin wall design that resists corrosion during extended outdoor use. Small openings in the frame reduce damage from freezing water, and the front is 3.2mm tempered glass. Pre-drilled holes make mounting easier.

Current-Matched Packing

SunGold groups and packs modules by current to reduce mismatch loss when they are wired together, and every module passes a 100% EL test. That matters when you buy a pack of panels for one string.

Electrical Limits for String Planning

The panel is rated for a 1500V maximum system voltage, with a 41.72V open circuit voltage, a 13.82A short circuit current and a 20A maximum series fuse rating. Wind resistance is rated at 2400Pa.

25-Year Output Warranty and 12-Year Workmanship Coverage

SunGold covers the panel with a 5 year 95% output warranty, a 10 year 90% output warranty and a 25 year 80% output warranty, plus a 12-year material and workmanship warranty.

Real-World Applications

Off-grid cabins. Supply a cabin's battery bank with quiet, clean solar energy from a few mid-size panels.

Campers and RVs. Add solar to a camper or RV with room for a 75.16-inch module.

Boats. The IP68 junction box makes the panel suitable for marine applications.

Professional installations. SunGold designed the panel for industrial and professional use, with a sealed aluminum frame built for years of outdoor service.

How It Compares to Common Alternatives

Versus smaller panels. Smaller panels fit tighter spaces, but you need more of them, with more mounting hardware and connections, to reach the same array wattage.

Versus mixing panel models. Strings built from one pack of identical SG450WM panels stay electrically consistent, and SunGold sorts modules by current to reduce mismatch loss. Mixing models in one string makes that harder.

Versus portable folding panels. A folding panel packs away, while this glass and aluminum module is built for permanent mounting and carries a 25-year output warranty.

Is This Monocrystalline Solar Panel the Right Fit

• Size. Each panel is 75.16 x 44.65 x 1.38 inches and 54 lbs.
• Voltage. Open circuit voltage is 41.72V per panel. Check your inverter or charge controller's PV voltage limit before planning series strings.
• Current. Short circuit current is 13.82A, with a 20A maximum series fuse rating.
• Climate. Rated to operate from -40°F to 185°F (-40°C to 85°C).

This may be a good fit if

• You have room for a mid-size module on a cabin, camper or boat
• You are buying several identical panels for one array
• You want a 25-year output warranty
• You need UL 61730 and CEC listed panels

Common Questions

How Much Energy Does a 450W Panel Produce Each Day?

On average, about 1.8 to 2.7kWh per day. The amount depends on your location, the time of year and the weather. Sunny areas land near the higher end, and cloudier areas near the lower end.

What Size Is the 450W Panel?

Each panel measures 75.16 x 44.65 x 1.38 inches (1909 x 1134 x 35mm) and weighs 54 lbs.

Can It Be Used Near Water?

Yes. The IP68 junction box makes the panel suitable for marine applications, and the waterproof design lets you use it in all weather conditions.

How Many Panels Can I Wire in Series?

That depends on your inverter or charge controller's maximum PV input voltage. Each panel's open circuit voltage is 41.72V, and it rises in cold weather (Voc temperature coefficient of -0.34%/°C), so leave headroom.
