SunGold Power 550 Watt Monocrystalline PERC Solar Panels | 32 Panels

SunGold Power 550 Watt Monocrystalline PERC Solar Panels Give Big Roofs and Ground Mounts 32 High-Output Modules on One Pallet

This pallet ships 32 SunGold Power SG550WM panels, and each one is rated 550W. The panels are monocrystalline PERC modules with 144 Grade A cells, 21.3% module efficiency and an IP68 junction box. They are UL 61730 certified and CEC Listed.

With 550W and a 49.7V open-circuit voltage per panel, this model is built for large arrays on commercial roofs, barns, open land and big homes. It also works for owners who want more wattage from every rack position and installers who want fewer modules to handle per kilowatt.

SunGold Power 550 Watt Monocrystalline PERC Solar Panels Features

144 Grade A Mono PERC Cells

Each panel carries 144 mono PERC cells measuring 182 x 91mm, arranged 6 x 24. SunGold uses Grade A cells with high conversion efficiency and says they perform well in low light.

21.3% Module Efficiency

SunGold rates the module at 21.3% efficiency, which turns more of the sunlight on each panel into usable power and keeps the array footprint down.

41.00V at Maximum Power

The panel produces 41.00V and 13.45A at maximum power, with a 49.7V open-circuit voltage and 14.03A short-circuit current. Higher voltage per panel means you reach a target string voltage with fewer modules in series, within the 1500V maximum system voltage.

Temperature Ratings

The power temperature coefficient is -0.38%/℃ and the nominal module operating temperature is 44℃ ±2℃. The panel operates from -40℉ to 185℉, and the maximum series fuse rating is 25A.

Twin-Wall Aluminum Frame With Pre-Drilled Holes

The frame is a sealed, scratch-resistant anodized aluminum twin-wall design that resists corrosion during extended outdoor use. Pre-drilled holes make mounting easier, and SunGold rates the panel for 2400Pa of wind pressure.

IP68 Protection

The IP68-rated junction box and waterproof connectors let the panel work in all weather conditions, and SunGold notes the design suits marine applications.

Real-World Applications

Commercial and industrial roofs. Cover large roof areas with high-output panels designed for professional applications.

Ground-mounted arrays. Install 550W modules on open land to keep the racking footprint efficient.

Off-grid properties. Supply a cabin, farm or full home with clean, quiet solar power.

Grid-tied and hybrid homes. Lower power bills and charge batteries with a large matched array.

How It Compares to Common Alternatives

Versus lower-wattage panels. Building the same array from smaller modules means more panels, more racking and more connections. At 550W each, the SG550WM cuts the module count.

Versus buying panels individually. A pallet gives you 32 panels with identical ratings in one shipment, so series and parallel strings stay matched.

Is This Solar Panel Pallet the Right Fit

• Panel size. Each panel is 89.7 x 44.8 x 1.4 inches and weighs 62.4 lbs. Plan racking, roof layout and handling for a large module.
• Freight. The packed pallet weighs 2150.0 lbs and measures 93 x 48 x 49 inches.
• Voltage limits. Check the 49.7V open-circuit voltage per panel against your inverter or controller's PV voltage requirement before you build strings.
• Fusing. The maximum series fuse rating is 25A.

This may be a good fit if

• You are building a large roof or ground-mount array
• You want 550W per module
• You use a high-voltage inverter
• You need UL 61730 certified, CEC Listed panels

Common Questions

Is the 550W Panel Waterproof?

Yes. The junction box and connectors are IP68 rated.

How Much Energy Can a 550W Panel Generate Daily?

It depends on the peak sun hours at your location. A 550W panel typically generates between 2.2 and 3.3 kWh per day.

Should I Wire These Panels in Series or Parallel?

That depends on your system voltage, your inverter specifications and any shading. Check the PV voltage requirement of your inverter or solar controller before you lay out the array.

What Warranty Do the Panels Carry?

Output warranties cover 95% at 5 years, 90% at 10 years and 80% at 25 years, plus a 12-year material and workmanship warranty.
