EF ECOFLOW 45W Portable & Foldable Solar Panel, 25% High-Efficiency N-Type Solar Cell, IP65 Waterproof & Dustproof, Design for Camping, Backpacks, SUVs, and Minivans

INCREDIBLY POWERFUL, STRONG AND WATER RESISTANT - USED OFF-GRID IN THE UK This panel is amazing. It produces up to 400W in direct bright sunshine but can produce as much as 40W even in heavy overcast in a UK summer with light rain falling. In very heavy overcast and heavy rain it will not work (obviously) but this would be a tall order for any solar system. I have used it in constant rain in the Lake District and Wales this summer, and been so chuffed that it continues to gather power in sub-optimal conditions. I have been blown away by how much energy you can harvest from the sun with this thing and though I am late to the party if I had more money to invest I would be buying an EcoRiver solar panel system for my house. The initial cost is high but it is more than worth it. This panel recharges my EcoRiver Delta 2 at full power (400W) in around two or three hours from flat. In overcast conditions it takes 6-8 hours to recharge the battery from 50% to 100%. The panel was able to endure the very strong winds and very heavy rain from Storm Betty recently while on holiday. I did have it attached using strong paracord to two strong trekking poles as a support system and it was carefully guyed down to strong tent pegs. At one point water was gushing along the panel, which was oriented uphill, forming a small river around 4 inches high. This is well beyond the expectations for water resistance for the panel and I was suitably amazed it survived - the electrical connections are sited about half way up the panel. The carry case is very good at doing just that - but perhaps not so good as a panel support which is its secondary use - see below. Suggestions for improvement Though this panel is amazing it is not superbly supported by the included case which doubles as a support system for the panel. The end result is a panel which sags and is not fully flat when angled using the case. I corrected this as described above by tying the corners with paracord to trekking poles but this was not a perfect solution. The powered, automated solar tracking support made by EcoRiver is an astonishing £2600 on their website (nearly £1000 more than the cost of the Delta 2 and this panel together!!) so I will be finding a cheaper solution to support the panel better. Some sort of lightweight but strong metal frame might be a good way of supporting the panel and in my view should be included in future versions. Additionally this is a very large and heavy panel. At 16kg it is uncomfortable to carry more than a short distance by hand and is large and unwieldy to put up - best done by two people. You don't get something for nothing - all that power has to come from plenty of surface area - and I don't regret buying this one bit. I will hopefully get years of use from it.

Ecoflow, quality and reliability love it

I am very pleased with the quality and performance. The only reason it did not get 5 stars is because it did not come with a lead to link it to the Delta 2 I bought at the same time. Having had both items shipped to my holiday destination ready to be off grid I then had to wait another four days before I could use it as I had to order the connecting lead. The solar panel arrived with a note to tell me what to order but it would have been helpful to either know in advance it to have it included in the order. Now looking forward to happy camping with the ability to charge cameras and other holiday gadgets with ease.

Not tried it yet so can’t really say to much however build quality looks good I wish it came with a couple of different leads so would save a time delay in getting some

Great product to accompany our Ecoflow power bank. Packs away under the bed of our motorhome and performs well with limited sunlight. We were pulling around 95 amps in November in Mull.

Excellent quality and produces a good charge. However the images on the sales description show four panels. The model I bought had 3 panels and it was definitely a 160W model. I will take photos and put them up for confirmation.

Great!! I like this panel very much very good power input I am going to buy another very soon to keep my electricity use down.

Great item but crap delivery service,just left out in the rain while we were away even though we told them to leave in open porch
