EF ECOFLOW NextGen 220W Portable Solar Panel, Bifacial Design Up to 25% Conversion Efficiency N-Type Solar Cell, with Adjustable Kickstand, IP68 Waterproof, Foldable for Camping/Home Backup

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.

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

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.

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.

The solar panel performed very well. On one day last month the total wattage on my 160 watt solar panel reached 155 watts. I was shocked that most most buyer reached about 120-130 watts at the max. The average each day depending on the weather reached between 85 watts on non sunny days, and on a full sunny day average between 120 watts and 135 watts output. The summer will be the biggest test when the sun is more powerful to each between 140 and 160 watts for most of the day.

It's bigger and heavier than I expected (my fault - I didn't take enough notice of the measurements) and since then it's been dark and overcast so I haven't yet been able to try it out. Looking forward to some sunshine to remedy that.

Ecoflow, quality and reliability love it

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

Rien à redire sur la marque de toute façon Je recommande ce produit

From limited testing (not much sun this time of year) all seems good. I also have the 100W folding panel from Ecoflow for a few years now and I am really happy with it. The 45W version seems just as well built.

Panneau solaire de très bonne qualité. Génère un bon courant, avec une bonne exposition fournit entre 53 et plus de 60w sur la sortie vers XT60 et 15w sur la sortie USB-C. Produit portable peu encombrant. Permet de recharger des téléphones, des batteries externes et des staions d'energie avec entrée XT60.

Paneel is niet geschikt voor mijn Powerstation en heeft ook niet de juiste aansluiting. Het werkte wel, ook met weinig licht.

Quando ho fatto l acquisto diceva che era con cavo mc4 da 2,5 metri con delle specifiche mi è arrivato tutto altro pannello solare e add oggi non voglino trovare una soluzione delusione più completa ps grazie all servizio clienti di ecoflow mi devo ricredere dopo avere capito il l'oro sbaglio anno provveduto a sostituire il pannello azzieda a disposizione del cliente grazie ecoflow
