Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For panels, safety means a stated weather code or protection: the EF ECOFLOW 45W states IP68 with an ETFE film, and the EBL 200W title states IP65. The RIVER 2 240 bundle states 5-year service, the strongest term here; the 45W panel states a warranty card in the box without a term. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| EF ECOFLOW RIVER 2 240 Bundle | 9.7 | 33 | 21 | 20 | 5 | 3 |
| EF ECOFLOW 45W Panel | 9.6 | 30 | 22 | 21 | 7 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best solar panel for EcoFlow RIVER 2
Check the maker’s own options first
The RIVER 2 240 bundle listing states a 256Wh LiFePO4 station with a 45W panel included, 300W output with up to 600W, 1-hour fast charging, 3000+ cycles before 80%, and 5-year service. The 45W panel listing states it is the ideal companion for RIVER series power plants, with a solar to XT60i charging cable in the box. Both name the RIVER line directly, which is the safest stated match. Browse the portable solar panels roundups for more options.
Match the wattage to the RIVER 2’s input
The Renogy 400W title states 400W, the EBL 200W title states 200W, the ZOUPW 100W title states 100W, and the EF ECOFLOW panel states 45W. The bundle states the 45W panel recharges the RIVER 2 240 in 7 hours. The RIVER 2 is a small station, so a 45W to 100W panel suits it; a 400W panel will be limited by the station’s stated solar input, which makes the bigger panels poor value for this station despite their wattage. Check the station’s manual for its input limit before buying a bigger panel.
| Pick | Stated watts | Stated weight | Weather code |
|---|---|---|---|
| EF ECOFLOW RIVER 2 240 Bundle | 45W panel | 10.8 lb bundle | Not stated |
| EF ECOFLOW 45W Panel | 45W | 3.1 lb | IP68 |
| Renogy 400W Foldable Panel | 400W | Not stated | Not stated |
| EBL 200W Panel 4-in-1 Cable | 200W | Not stated | IP65 |
| ZOUPW 100W XT60 Panel | 100W | Not stated | IP67 |
Mind the weight and the fold size
The 45W panel states 3.1 pounds and folds to 8.7 by 12.2 by 1.8 inches, fitting a backpack per the listing. The bundle states 10.8 pounds for station and panel together. The other three listings state no weight. For a small station meant to travel light, the stated 3.1 pounds is the standout figure.
Check the weather code and the mounting
The 45W panel states IP68 with a protective ETFE film, the highest stated weather code here. The ZOUPW 100W title states IP67, and the EBL 200W title states IP65. The 45W panel also states four pre-cut grommets and snap hooks for hanging on a car or backpack, plus lying flat or tilted on a stand. A stated IP68 means the panel keeps working through downpours.
Check the efficiency and the cable
The 45W panel states 25% conversion with N-type cells. The ZOUPW 100W title states 23.5%. The 45W panel includes a solar to XT60i charging cable; the EBL 200W title states a 4-in-1 cable. The RIVER 2 uses an XT60i input per the cable naming, so a stated XT60i cable is the direct match.
Note the bundle includes the station
The RIVER 2 240 bundle listing is a station plus panel kit, not a panel alone: it states the RIVER 2 240 with 256Wh, 300W output and up to 600W, plus the 45W panel. Score it as the complete kit. If you already own a RIVER 2, the standalone 45W panel is the pick; if you own neither, the bundle states everything in one box.
Sizing Notes
- Match the panel’s stated wattage, 45W to 400W here, to the RIVER 2’s stated solar input limit.
- Match the stated connector, solar to XT60i on the 45W panel, to the station’s input port.
- Match the stated weight, 3.1 pounds on the 45W panel, to how far you carry it.
- Match the stated weather code, IP68 on the 45W panel, to your rain exposure.
