32 Panels · 17.6kW Total · 550W Each · 21.3% Efficiency · UL 61730 & CEC
SunGoldPower 550W Mono PERC Solar Panel Full Pallet (32 Panels)
A full pallet of 32 SunGoldPower 550W panels — 17.6kW of array in a single shipment, at pallet pricing. This is how you buy panels when you're building a real system rather than adding a couple: one freight delivery, one batch of matched modules from the same production run, and a materially lower cost per watt than buying in pairs.
Matched modules matter more than people expect. Panels from the same batch have closely matched electrical characteristics, which means a string performs to its weakest module less severely than a string assembled from panels bought months apart. The highest-wattage monofacial panel in SunGoldPower's range at 550W, and the lowest cost per watt for a large ground mount or commercial roof where module size is not a constraint. Renewable Outdoors is an authorized SunGoldPower dealer — call us at (303) 876-7654 and we'll work out string sizing against your inverter before you order.

Why the SunGoldPower 550W Panel
550W at 21.3% Efficiency
21.3% module efficiency at 550W — the most watts per module in the monofacial range.
Lowest Cost per Watt
At this size, fewer modules and fewer mounts for the same array power is where the money is saved.
2400 Pa Wind Rating
3.2mm tempered glass in an anodized aluminium frame with an IP68 junction box.
UL 61730 and CEC Listed
Certified for permitted grid-tied installation at up to a 1500V system voltage.
80% Output at 25 Years
Twelve years on materials and workmanship with a stepped performance guarantee.
89.7 Inches — Plan the Handling
A big module at 62.4 lbs. Excellent value on a ground mount, awkward on a steep roof.
What's Included
On the Pallet
32 × SunGoldPower 550W solar panels (SG-550WM)
Palletised and crated for freight delivery
Datasheet and warranty documentation
This ships by freight, not parcel. You'll need somewhere a lorry can deliver and a way to unload — a forklift, a tractor with forks, or several people and a plan. Inspect the pallet before you sign for it and note any damage on the delivery paperwork; that's what protects a freight claim. Call us at (303) 876-7654 and we'll confirm delivery requirements for your site.

SunGoldPower 550W Mono PERC Solar Panel Full Pallet (32 Panels): Frequently Asked Questions
How many 550W panels do I need?
Work backwards from your daily energy use and your inverter's limits. As a rough guide, one 550W panel produces somewhere around 2.2kWh on a good day in a sunny climate and considerably less in winter or under cloud. Your inverter's maximum PV input and MPPT voltage window then cap how many you can string together. Call us at (303) 876-7654 with your inverter model and your usage and we'll size it properly with you.
How do I work out how many panels go in a string?
Divide your inverter's maximum PV input voltage by the panel's open circuit voltage, then subtract one for cold-weather margin — Voc rises as temperature falls, and a string sized at the limit on a mild day can exceed the inverter's ceiling on a freezing morning. These panels are 49.70V Voc with a −0.35%/°C temperature coefficient. We do this calculation for customers all the time, so call us rather than guessing.
Will the panels actually produce their rated wattage?
Rarely, and that's normal for every panel from every manufacturer. Rated power is measured at Standard Test Conditions — 1000W/m² irradiance at a 25°C cell temperature — which is brighter and cooler than a real roof on a summer afternoon. Expect 75 to 85 percent of nameplate in good conditions once the panels warm up. Size your array on that basis rather than on nameplate and you won't be disappointed.
What certifications do these carry?
UL 61730, CEC Listed, CE, TUV, IEC, CB, ISO 9001:2015. The one that usually matters for a permitted grid-tied installation in the US is the UL listing and CEC listing, because inspectors and utilities ask for them. If your jurisdiction has specific requirements, tell us and we'll confirm before you order.
What does the warranty actually cover?
Two separate things. The product warranty — 12 years materials and workmanship — covers defects in materials and workmanship. The performance warranty — 95% at 5 years; 90% at 10 years; 80% at 25 years — guarantees the panel still produces a stated percentage of its original output at given years. Performance warranties are the more meaningful of the two over a panel's life, since panels rarely fail outright but all of them degrade.
Can I mix these with panels I already own?
On the same string, no — you should not mix panels of different wattage or electrical characteristics in series, because the string performs to the weakest module and you lose more than you'd expect. On separate MPPT inputs, or as a separate string on the same inverter, mixing is usually fine. Call us at (303) 876-7654 and describe what you have and we'll tell you what works.
What mounting hardware do I need?
That depends on whether you're going on a roof, a ground mount or a pole. These panels are 89.7" × 44.8" × 1.4" (2278 × 1134 × 35mm) and 62.4 lbs (28.3 kg) each, which is what your racking has to be rated for. We stock SunGoldPower's modular ground mount brackets for two panels, and we can advise on roof racking. Wind and snow loading matter a great deal here — it's worth a conversation rather than a guess.
Do you offer financing or price matching?
Yes. We offer 0% APR financing options through Affirm at checkout, and our Lowest Price Guarantee applies — if you find these panels cheaper at another authorized dealer, call us at (303) 876-7654 before you order and we'll take care of it.
