EcoFlow Solar Panels Reviewed 2026: Which Panel Is Right for Your Station?
EcoFlow's solar panel lineup spans from a 28W USB-only charger to the 220W bifacial panel designed for DELTA Pro installations. Matching the right panel to your power station matters — an undersized panel takes 12+ hours to fill a 1 kWh station; an oversized panel may exceed your station's solar input limit. This guide covers EcoFlow's core panels and how to match them to your station.
The EcoFlow 220W Bifacial — the headline product
The bifacial design is the 220W panel's defining feature. Standard portable solar panels are single-sided; EcoFlow's bifacial panel captures direct sunlight on the front AND reflected ambient light on the rear. Real-world testing shows 15–22% additional output from rear-side capture on light surfaces (gravel, sand, white tarp). In testing on direct sun with white ground cover, the 220W bifacial panel produced ~15% more power than a single-sided 220W equivalent — effectively giving you a ~253W output from a 220W-rated panel. IP68 waterproofing is the secondary differentiator: leave it out in rain, no damage. Built-in angle guide (30–60°) eliminates guesswork for beginners.
When bifacial matters (and when it doesn't)
Bifacial rear-side gain is directly tied to ground reflectivity. Place the panel on dark soil or asphalt and the rear gain drops below 5% — not worth the 20.9 lb weight premium over a 15.4 lb single-sided panel. Place it on light gravel, white paint, sand, or a silver emergency blanket and the 15–25% rear gain is real and measurable. For rooftop installation or elevated ground mounts, bifacial panels are standard in commercial installations for this reason. For ground-level camping on dark forest soil, the 160W is the better weight-to-output choice.
EcoFlow 160W Portable — the everyday choice
At 15.4 lbs and ~$249, the 160W is EcoFlow's most versatile portable panel. Folds to a briefcase form, deploys in seconds, IP68 waterproof. Peak output of 150W+ in direct noon sun; expect 100–120W in typical use conditions. This is the panel to pair with River 2 Pro (fills in ~3.5 hours) or DELTA 3 Plus with a second panel (combined 320W fills in ~3.5 hours). The 22% efficiency matches premium single-sided panels from other brands.
Matching panels to stations — the compatibility table:
• River 3 (110W solar max): EcoFlow 110W panel or any panel up to 110W/30V
• River 2 Pro (220W solar max): EcoFlow 160W panel (fills in ~3.5 hours)
• DELTA 3 Plus (1,000W dual input): One 220W bifacial + one 160W fills in ~2.5–3 hours
• DELTA 2 Max (1,000W dual input): Two 220W bifacial panels fills in ~2.5 hours in good sun
• DELTA Pro (1,600W solar max): Three 220W bifacial panels fills in ~3.5 hours; four panels in ~2.5 hours
Third-party panels with EcoFlow stations
EcoFlow stations accept any solar input via the XT60i (or included adapter) at the correct voltage and wattage. Third-party panels from Jackery, Renogy, Goal Zero, and generic brands work fine electrically. The connector type may differ — check compatibility or buy an XT60 adapter. Third-party panels can be significantly cheaper per watt than EcoFlow-branded panels, particularly for non-portable rooftop or fixed-frame installations.
Budget solar options
The ALLPOWERS SP027 at $89 for 100W is the most affordable capable foldable panel in this guide — 21% efficiency, IPX4 splash resistance, and enough output to meaningfully charge any River station. At $89 vs. $249 for EcoFlow 160W, the ALLPOWERS saves $160 for 60W less peak output and IPX4 vs. IP68. For casual camping in fair weather, the ALLPOWERS is a strong budget choice. The BigBlue 28W at $72 is a USB-direct panel (no AC inverter) — useful only for phone/earphone charging without a power station; not appropriate for charging any EcoFlow unit directly.
Efficiency vs. wattage — the outdoor solar math
"22% efficiency" means the panel converts 22% of sunlight hitting it into electricity. A 160W panel at 22% efficiency and 1m² area converts ~220W/m² × 22% = approximately correct. Real-world panel output depends on: sun angle (60–80% of rated output at optimal angle), temperature (panels lose efficiency in heat — ironically better on cool sunny days), shading (even partial shading drops output significantly), and age (1–2% degradation per year). Plan for 60–70% of rated wattage in practical camping conditions.

ALLPOWERS SP027 100W at $89 — monocrystalline ~21% efficiency, IPX4 splash resistant, ~11 lbs, foldable. The best budget entry into serious portable solar: $89 for 100W significantly undercuts EcoFlow's panel pricing. IPX4 handles light rain but not the extended exposure that IP68 handles. Compatible with all EcoFlow stations via MC4 to XT60 adapter. Fills EcoFlow River 3 (245 Wh) in ~2.5 hours; meaningfully contributes to River 2 Pro and DELTA 3 Plus charging. For campers who want solar capability without premium panel pricing, and will retrieve the panel if heavy rain arrives, the SP027 is excellent value at $89. Approximately $160 cheaper than EcoFlow 160W for 60W less peak output.
