SunGoldPower 460W Bifacial PERC Solar Panel (SG-460WBG)
460W per panel at 21.25% module efficiency, sold in the quantity you actually need rather than a full pallet. A dual-glass bifacial PERC module at 460W, built for ground mounts and elevated racking where the rear face can see reflected light.
PERC monocrystalline 182 × 91mm, 120 half-cells (6 × 20) behind dual 2.0mm heat-strengthened glass, in an anodized aluminium frame rated for a 1500V DC system voltage. Ten years on workmanship with a 25-year linear performance warranty. Renewable Outdoors is an authorized SunGoldPower dealer — call us at (303) 876-7654 and we'll check string sizing against your inverter's MPPT window before you order.

Why the SunGoldPower 460W Panel
460W at 21.25% Efficiency
21.25% front-face efficiency at 460W, with bifacial rear-face gain on top.
Dual Glass Construction
2.0mm heat-strengthened glass front and back rather than a polymer backsheet — more durable in harsh environments.
Anti-Reflective Front Glass
AR coating on the front glass increases transmission into the cells.
TUV, IEC and CEC Certified
Independently certified at up to a 1500V system voltage. Note UL 61730 is not published for this model.
25-Year Linear Warranty
Ten years on workmanship with a 25-year linear performance guarantee.
Bifacial on a Ground Mount
Elevated racking over a light surface is where a bifacial module earns its premium.
What's Included
What You Get
SunGoldPower 460W solar panels (SG-460WBG) in the quantity you select
Pre-attached 4mm², 300mm each leads with MC4 compatible connectors
Datasheet and warranty documentation
Mounting hardware, racking, cabling beyond the panel leads, combiners and fusing are separate purchases. A full pallet is 31 panels and works out cheaper per watt if you need that many — we list that separately. Call us at (303) 876-7654 and we'll price the whole array.

SunGoldPower 460W Bifacial PERC Solar Panel (SG-460WBG): Frequently Asked Questions
How many 460W panels do I need?
Work backwards from your daily energy use and your inverter's limits. As a rough guide, one 460W panel produces somewhere around 1.8kWh 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 41.75V Voc with a −0.28%/°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 does bifacial actually gain me?
The rear face generates power from light reflected off whatever is underneath the panel, so the gain depends entirely on your surface and mounting height. A white roof, a concrete pad or snow cover can add real output; dark soil or grass adds very little, and a flush roof mount adds almost nothing because there is no gap for light to reach the back. SunGoldPower does not publish a bifaciality factor for this model, so size your array on the front-face rating and treat anything the rear contributes as upside.
What certifications do these carry?
TUV, IEC, CEC, CE, CB, ISO 9001:2015 / 14001:2015 / 45001:2018. 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 — 10 years workmanship — covers defects in materials and workmanship. The performance warranty — 25-year linear product workmanship warranty — 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 75.16" × 44.65" × 1.38" (1909 × 1134 × 35mm) and 60.6 lbs (27.5 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.
