Ecoflow 220W Bifacial Solar Panel Review: The best portable solar panel?

[@234yellow]

Very nice review. This information was just what I needed. I just bought the ecoflow 220W bifacial solar panel and I wondered how well it would work with my 2 Delta2 1024W batteries. Thank you for doing the real time charging that shows it was able to go beyond the stated charging capacity. You may have convinced me to purchase an additional 220W panel. I have a 110W panel also but all information I have reviewed tells me I can not connect in parallel to get 330W, because I need to have them both at the same ratings. Thanks again for the nice review

Glad you found it useful - thanks for watching.

I just bought a deal with the delta 2 with tat same portable panel. I have not been able to test it but i am impressed by your test. I was not expecting such a great perfo

[@ttl_channel]

Glad I could help. Thanks for watching.

Did you ever try it out? I'm looking at buying the same combination on sale for $700 (Delta 2 with this older style (with superb efficiency) 220w panel) I just realized this panel comes with the XT60 adapter but I believe the Delta 2 has the XT60i jack and it comes with the XT60i adapter cable anyway. Let me know how it goes!! Thanks! EDIT: I'm wrong. The Delta 2 doesn't come with a XT60i solar adapter cable. So my question is, will the XT60 adapter that comes with this panel fit into the Delta 2's XD60i jack?

Excellent review and similar results I've obtained from these panels. Ecoflow seem to be leading the field in performance and innovation and it's hard to fault their products. Have a Delta Max 2 and it functions exceptionally well. Looking forward to the release of the Delta Pro 3 which seems a very capable unit. Thanks for sharing your impression with these products.

Glad you liked it. Thanks for watching

[@rgraz4929]

Come to think of it, I think you're getting good results, in part, because of the light being reflected off of your white garage doors and yellow siding to the rear of the bifacial panels.

[@ttl_channel]

Good point!

[@JM_1111j]

Thank you for this review! Do you think 2x200w solar panels are better than 1x400w solar panel (both offered by EcoFlow)? Or vice versa?

[@ttl_channel]

I have no experience with the 400W, but I will say that the 220's are already pretty big, so I would imagine that the 400 is huge and maybe a bit difficult to work with. Also, having 2 x 220 would give you more versatility - e.g. to just use 1 panel for a quick top-up, without having to get out a giant 400. Just food for thought.

[@rgraz4929]

Great review. I'm just starting to research power stations and panels. Do you think the newer EcoFlow bifacial panels (with the metal stands) are better panels, excluding the fact that they have a better stand? I notice the panels themselves look different. Thanks! TOO ADD: There's an EcoFlow Delta 2 1024Wh that includes a 220v bifacial solar panel for $700 USD (with coupon). But it's the same panel you have here, that uses the case as the stand. Thx.

[@ttl_channel]

I would hope that the “upgraded” panel is at least as efficient, but I do not have one to test. The metal stand is definitely an improvement.

[@rgraz4929]

​@@ttl_channel You did get some great results with that panel. Let me know if you thought about, or assembled any stand solutions. Maybe something permanently hinged to the top of the panel but will still fit int he case? Thanks.

[@mrdespizeme]

Do you have the capability to test in parallel? I'm curious how much the wattage would vary in parallel. Also, doesn't the Ecoflow Delta Max have 2 connections in the back for 2 solar panels?

[@Sommitps]

Regarding the bag, which isn't waterproof (and that is actually the reason I haven't pushed the button on this one yet)... what if you turned it outside in, as the inside of the bag seems to be a material that would be waterproof/resistant?

[@ttl_channel]

I don’t think that would work and I’m not sure the interior material is any more waterproof or sturdy.

[@Equinox68]

I bought this going in knowing the biggest complaint was using the case as a stand. I just constructed a pvc frame with elbows and made a kickstand that attaches to the top pole to be able to tilt it. It breaks down to single poles real fast for easy storage.

[@gregstafford2155]

I wonder if the panel is using MPPT controller inside? A victron MPPT attached to these panel would even be greater I would think

[@ttl_channel]

According to Ecoflow, the Delta Max's charge controller is MPPT.

[@juliandwyer9367]

Panels do not have a controller and so one would need to purchase a separate controller. People who have a Ecoflow Delta series power pack will have a MPPT controller built into their pack and so it functions nicely with those products.

[@mahfah7911]

So these 2 can be added for 440!? But 110+ 220 makes it slower to charge ! Am I correct ?? Also, what 3rd party affordable option I can add with 220 bifacial which is compatible in volts etc?!

[@ttl_channel]

If you mix different panels, probably best to link in parallel, but manufacturers generally don’t recommend mixing. Sorry, I have no experience with other biracial panels.

[@hardtruth2039]

What size pv cable were you using for extensions? 12awg, 10awg or 8awg. They are also offering these panels with a new metal kickstands.

[@ttl_channel]

Good question: my cables are 12AWG.

[@1jzMKIII]

And Echo is what you hear when you shout into a canyon.... its EcoFlow not EchoFlow.

[@Ellifiknow]

All I can hear is a pedantic jerk.

[@HoneyBerighthere-Saysarath]

750watts for a 120watts, house fan. So, 1500 should work for a 240 watts, AC window U shap unit.

[@deeperstillll2151]

Let us know what you found for a better panel stand.

[@ttl_channel]

Nothing so far...beyond leaning them against stuff!

[@marccawood]

Disingenuous to design a panel on the back (in the shade) giving maybe 10% more power instead of just letting people fold it out into full sunshine and giving 100% more power.

[@ttl_channel]

Well they do make a panel twice the size/power, but it’s almost twice the price.

[@marccawood]

@@ttl_channel no… solar on the shady side is not anything like solar in the sun. I’m guessing 90% less effective

[@adjake1]

Buyer beware. Ive now had 2 of ecoflows 160watt portable panels. Both have failed within 9 months. They put out 1/4 of their rated power after 9 months. One was replaced under warranty and the replacement panel they will not replace. Customer service is worthless, they know nothing about their products.

[@ttl_channel]

Interesting! Hopefully, I will have a better experience.

[@MosaicHomestead]

Ridgit panels are better, the durability quality on these portable panels are usually not the best, I tested a 380w monocrystaline solar panel yesterday on a bad day that gave me better results than what you got on this video, and at $150, it's practically less than 1/6 what you paid or less.
