The ECOFLOW Pro description on desertcart included the words "Solar Generator for Home Use", but the solar panels are sold separately. The solar panels and battery unit were easy to set up. Battery can be charged quickly from wall outlet and much slower from solar panels. Battery has 4 AC outlets. Although it is fairly heavy, battery unit comes with wheels and a collapsible handle similar to today's travel bags. Solar panels are a slow way to recharge and totally dependent on sun. They work well for 4-5 hours at mid day in SE Texas, but do not work at night and work poorly in the morning, evening and when cloudy. However, the 800W's of solar panels I used produced a peak of 695W at mid day with no clouds. I have experience with 12 roof top solar panels and this performance by these folding, portable panels is very good. I used the system to power my refrigerator (about 5 hours each day), my entertainment system (including TV, DVR, DVD player, sound system, WiFi, laptop), a lamp and a radio phone. I also, when needed, used it to power a garage door opener, chain saw, microwave oven, hair dryer and recharged backup batteries for my iPhone, home security base station and fiber optic cable connector. Solar panels come with water resistant, padded carrying cases that are also designed to support the solar panels if you need them at an angle.

I am currently running my garage refrigerator, a couple of battery maintainers for my cars and a motion activated light that comes on when I walk into the garage. The panels does a good job of charging my Delta Pro on most days and even charges a bit on hazy days, but of course not as much. It's winter time now and the sun is low in the horizon and shines fewer hours than in the summer so I'm thinking that I will be able to connect more things to it once summer rolls around. So far I am very pleased with its performance and I think it is only going to get better. The panel is portable but it does weigh a little bit due to its robust construction. I prefer that it is tougher and a bit heavier than lighter and flimsier, especially if it is going to moved about from place to place. It's not exactly cheap, but then you do get what you pay for and this is worth the price. ## 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.be/products/436765871-400w-portable-solar-panel-foldable-and-durable-complete-with-adjustable](https://www.desertcart.be/products/436765871-400w-portable-solar-panel-foldable-and-durable-complete-with-adjustable) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-04-29*
