EcoFlow 125W Bifacial Modular Solar Panel — 125W, 250W and 500W Kits
This is the panel to buy when you want a semi-permanent solar array rather than something you fold up at the end of the weekend. TOPCon cells push conversion efficiency to 25%, and the bifacial rear face harvests light reflected off the ground, a wall, or a light-coloured roof — adding up to 138W from a panel rated 125W on the front alone.
The modular design is the other half of the appeal: up to eight panels can be paralleled for 1000W, so you can start with one and grow the array as your needs do. IP68 sealing on both the panel and the XT60 connector, 1.1mm tempered glass, a 30-year design life, and a 5-year warranty. Renewable Outdoors is an authorized EcoFlow dealer — call us at (303) 876-7654 and we'll size the array for your power station.

Why the 125W Bifacial Modular Panel
25% Conversion Efficiency
TOPCon monocrystalline cells, among the most efficient available in a panel this size — more watts from the same footprint.
Bifacial: 125W Front, 138W Rear-Boosted
The rear face captures reflected light with an 80% bifaciality coefficient, so a bright surface underneath is free extra output.
Parallel Up to 8 Panels (1000W)
Start with one and expand. The modular frame and XT60 connectors mean adding a panel is a five-minute job, not a rewire.
IP68 Panel and Connector
Sealed to IP68 at both the panel and the XT60 connector, so it can live outdoors year-round rather than being packed away.
Works from −40°F to 185°F
TOPCon cells hold their output better in heat and in low light than older cell technologies — useful in both summer and winter.
30-Year Design Life
Rated to still deliver 90% of original output at 30 years, on 1.1mm tempered glass in an anti-corrosive frame.
What's Included
In the Box
125W bifacial modular solar panel(s) — one, two, or four depending on the option you choose
Integrated adjustable kickstand on each panel (30–60°)
XT60 solar cable on each panel
500W kit: parallel extension cables and MC4-compatible connectors
User manual and warranty card
Power station bundles ship the panels alongside the power station in separate cartons. Check your power station's maximum solar input before adding panels — we're happy to confirm it for you.
Which Configuration Should You Choose?
The panel itself is identical in every option — what changes is how many you get and whether a power station comes with them.
Option
What You Get
Best For
125W Single Panel
One panel, 125W front / 138W bifacial
Topping up a small power station, or starting an array you plan to grow
125W × 2 (250W)
Two panels, 250W front / up to 276W bifacial
A realistic day-to-day charge for a mid-size power station, still easy to place
500W Solar Kit
Four panels plus extension cables and MC4-compatible connectors
A proper semi-permanent array — RV roof, cabin, or backyard ground mount
DELTA Pro + 500W Kit
DELTA Pro 3600Wh power station with the four-panel kit
A complete off-grid or backup setup built around the original DELTA Pro
DELTA Pro 3 + 500W Kit
DELTA Pro 3 4096Wh / 4000W power station with the four-panel kit
The current-generation flagship — 120/240V output and the fastest recharge
DELTA Pro Ultra + 500W Kit
DELTA Pro Ultra inverter and battery with the four-panel kit
Whole-home capable backup with solar, expandable to 90kWh
DELTA Pro Ultra + 2 × 500W Kit
DELTA Pro Ultra with eight panels — 1000W of solar
Maximum solar harvest on a DELTA Pro Ultra, using the full 8-panel parallel limit
Eight panels in parallel is the documented maximum for this panel, which is exactly what the two-kit DELTA Pro Ultra option gives you. If you want a larger array than 1000W, call us at (303) 876-7654 and we'll look at EcoFlow's rigid panels instead.
Backed by EcoFlow's manufacturer warranty, with a 30-year design life on the panel itself.

EcoFlow 125W Bifacial Modular Solar Panel — 125W, 250W and 500W Kits: Frequently Asked Questions
What does bifacial actually mean, and will I really get 138W?
The rear face of the panel generates power too, from light bouncing off whatever is underneath it. The 125W figure is the front face measured under standard test conditions; 138W is the bifacial figure. How much of that extra you see depends entirely on your surface — a light concrete pad, a white RV roof, or snow will give you a real boost, while dark soil or grass will give you very little. Treat 125W as the number to plan with and the bifacial gain as a bonus.
How many panels can I connect together?
Up to eight in parallel, for 1000W total. That is the documented maximum for this panel. Just as important is your power station's own solar input ceiling — connecting more panel than it can accept won't damage anything, but it won't charge faster at peak either. Call us at (303) 876-7654 with your model and we'll work out the right number.
Can I leave these outside permanently?
Yes — that's what they're designed for. Both the panel and the XT60 connector are sealed to IP68, the frame is anti-corrosive aluminium, and the glass is tempered. They're rated from −40°F to 185°F and designed to hold 90% of their output at 30 years. This is a semi-permanent array panel rather than a fold-up-and-carry one.
Will it work with a non-EcoFlow power station or charge controller?
The panel outputs through an XT60 connector, and the 500W kit includes MC4-compatible connectors, so it can feed a third-party charge controller or inverter as long as the voltage and current are within that device's MPPT range. Check your controller's input window against the 50V open-circuit voltage first — call us if you'd like a second pair of eyes on it.
What is the difference between this and EcoFlow's portable folding panels?
Folding panels like the 160W and 220W are built to be carried, set up, and packed away — canvas cases, kickstands, lower efficiency per pound. This one is a rigid glass-and-aluminium panel meant to stay where you put it, with higher efficiency, a bifacial rear face, and modular parallel expansion. If you're camping, buy folding; if you're building an array on a roof, cabin, or pad, buy this.
How should I mount them?
Each panel has an integrated kickstand adjustable from 30 to 60 degrees, which is enough for ground or flat-roof placement. For a pitched roof or a permanent RV installation you'll want a proper mounting solution rather than the kickstand — we stock EcoFlow's rigid mounting hardware and can advise on what suits your surface.
Which power station should I pair a 500W kit with?
Anything that accepts at least 500W of solar input. The DELTA Pro, DELTA Pro 3, and DELTA Pro Ultra bundles on this page all comfortably clear that. For smaller units a single panel or the 250W pair usually makes more sense. Tell us what you already own on (303) 876-7654 and we'll match it up.
Do the power station bundles include everything I need?
Yes — the power station, four panels, the parallel extension cables, and MC4-compatible connectors. You may still want additional extension cable if the panels will sit a long way from the power station, and a mounting solution if you aren't using the built-in kickstands.
What warranty comes with it?
Up to 5 years of manufacturer warranty from EcoFlow, alongside a 30-year design life rating on output. We're an authorized dealer, so warranty claims go through the normal EcoFlow process with our support behind them.
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 this panel or kit cheaper at another authorized dealer, call us at (303) 876-7654 before you order and we'll take care of it.
