These are lightweight and portable and very efficient, rated at around 24%. They also have additional collectivity on the reverse side of the panel. These are well-made and integrate well with many applications. The manufacturer supplies the correct universal connecting cable from the solar panels to the EcoFlow Delta 2 power station. The EcoFlow 220 W bifacial solar panel provides adequate results when there is direct full sunlight to collect the sun's solar energy. EcoFlow has improved the set up from the previous generation and has remove the awkward combination carry case and flimsy set up stand, which was awkward and cumbersome to set up at the right angle for use. The new design has four flip out panels with attached angled metal stands off the back that allow the user to place the panels at the correct angle toward the sun. These panels are very rigid but want to return to their fold up position so it will take a while to unfold these with the stands. After initially setting up the panels with the Delta 2 solar power station, the input wattage shows about 151 W at the end of December in Winter sunlight. in Connecticut. The sun is at a low angle in the sky and this is about the most wattage I can get in the winter northeast. I recommend using a light finder to optimize the angle to get the maximum amount of input wattage. I will redo this test in the spring and on the summer solstice in June to see increased differences in the northeast. One thing to understand is that I have not used the reflectivity of the back panels to add additional wattage by using a reflective material since these were set on a black driveway. I will try using these panels on a white snow surface to see what additional wattage I get from the rear facing panels. They certainly put out a lot more wattage than the Harbor Freight salvage 100 W panels that are available. When I move the solar panels into the partial shade from a large maple tree, the input wattage went down and fluctuated between 80 and 50 W input. Each of these panels put out about 55 W of power and the way they’re wired is that you can have partial shade on two of the panels and still get about 110 W of power input. When three or four panels are in the shade of the maple tree I was only getting about 31 W which is still impressive. My initial impression is that these are one of the best portable efficient solar panels on the market in this price range. I’ve looked at other YouTube reviews, and some of the evaluators have determined that they can get well over 210 W of power in the full sun in the summertime. Keep in mind that this may still require several days of charging your EcoFlow Delta two power station if you only get four hours of full sun per day. However, if you live in a area with direct full sun for more than eight hours, and you will be able to recharge your 2200 W power station in one day. ## Features - [High Performance] With a 400W power input, this solar panel can provide your power station with a significant amount of energy with outstanding efficiency. - [Extremely Portable] The EcoFlow 400W Solar Panel is foldable and comes with an adjustable carry case. Weighing in at only 16kg (35.3lbs) it can be easily packed up and carried with you, no matter where you go. - [Weather Proof] This 400W solar panel is built to withstand the elements.

Its high transparency allows for a high energy conversion rate. - [Astonishing Efficiency] When paired with an EcoFlow power station, the 400W solar panel utilises the MPPT algorithm to achieve optimal efficiency rain or shine. Where solar panels are concerned, its conversion rate of 22.4% is astonishing. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09TKKYW7G | | Brand | EF ECOFLOW | | Connector Type | MC4 | | Customer Reviews | 4.5 out of 5 stars 876 Reviews | | Efficiency | High Efficiency | | Included Components | Bag | | Included components | Bag | | Item Type Name | 400W Solar Panel | | Item Weight | 35.3 Pounds | | Item weight | 35.3 Pounds | | Manufacturer | EF ECOFLOW | | Material | Monocrystalline Silicon | | Maximum Power | 400 Watts | | Maximum Voltage | 45 Volts | | Maximum voltage | 45 Volts | | Model Number | EF-Flex-400 | | Part Number | Solar Panel | | Special Features | High Performance, Extremely Portable, Weather Resistant, State-of-the-Art Technology | | UPC | 842783146793 | ## Product Details - **Brand:** EF ECOFLOW - **Efficiency:** High Efficiency - **Included components:** Bag - **Item weight:** 35.3 Pounds - **Material:** Monocrystalline Silicon ## Images ![EF ECOFLOW 400W Portable Solar Panel, Foldable & Durable, Complete with an Adjustable Kickstand Case, Waterproof IP68 for Outdoor Adventures - Image 1](https://m.media-amazon.com/images/I/71yGQH024YL.jpg) ![EF ECOFLOW 400W Portable Solar Panel, Foldable & Durable, Complete with an Adjustable Kickstand Case, Waterproof IP68 for Outdoor Adventures - Image 2](https://m.media-amazon.com/images/I/81NfG70cvXL.jpg) ![EF ECOFLOW 400W Portable Solar Panel, Foldable & Durable, Complete with an Adjustable Kickstand Case, Waterproof IP68 for Outdoor Adventures - Image 3](https://m.media-amazon.com/images/I/816IvW9NYjL.jpg) ![EF ECOFLOW 400W Portable Solar Panel, Foldable & Durable, Complete with an Adjustable Kickstand Case, Waterproof IP68 for Outdoor Adventures - Image 4](https://m.media-amazon.com/images/I/7117FmhUQlL.jpg) ![EF ECOFLOW 400W Portable Solar Panel, Foldable & Durable, Complete with an Adjustable Kickstand Case, Waterproof IP68 for Outdoor Adventures - Image 5](https://m.media-amazon.com/images/I/81VEqOf8pcL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ producto recomendado *by A***N on 18 September 2023* Panel solar trabaja al 100%, envió y entrega satisfactoriamente ### ⭐⭐⭐⭐⭐ One of the Best Portable Solar Panel Collection Systems *by L***T on 1 January 2025* I purchased the EcoFlow 220 W bifacial solar panel panels and want to share my initial evaluation and impressions.

On sunny days here on Vancouver Island, I was getting between 135 and 145 watts, which was better than I expected from a 160W panel. One feature I really like is the solar alignment guide at the top front of the panel. It made it easy to point the panel directly at the sun, and I could actually see the wattage increase as I adjusted it. The panel feels well made, is easy to set up, and folds up nicely for transport. I bought it mainly for camping and to keep my power station charged for my CPAP, and it has worked exactly as I hoped. If you're looking for a portable solar panel for an EcoFlow power station, I'd definitely recommend this one ## Frequently Bought Together - EF ECOFLOW 400W Portable Solar Panel, Foldable & Durable, Complete with an Adjustable Kickstand Case, Waterproof IP68 for Outdoor Adventures - EF ECOFLOW 120V Home Backup Kit: DELTA Pro 3600Wh Power Station with Transfer Switch Kit, 3600W AC Output, Solar Generator for Home Use, Emergency, RV - EF ECOFLOW DELTA Pro Extra Battery 3600Wh, 2.7H to Full Charge, Battery Backup for Home Use, Blackout, Camping, RV --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/668642814-ef-ecoflow-400w-portable-solar-panel-foldable-and-durable-complete](https://www.desertcart.at/products/668642814-ef-ecoflow-400w-portable-solar-panel-foldable-and-durable-complete) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-07-26*
