Made the mistake and purchased these panels. They only output 52 watts in deal conditions. Retuning them was a nightmare so I filed a dispute with my credit card and got all my money back.

North or South us? Summer or winter?Solar panels only put out the rated power, during summer, on a clear sunny day, pointed at the sun, for a few hours a day during peak

Full Disclosure - I went to the Madera Swap Meet on a sunny day, and I was trying to sell some electronics (CradlePoint routers). I took this panel along with my EcoFlow RIVER 2 Portable Power Station 256Wh to power my routers. A guy saw my setup and was impressed by the performance of the panel. I didn't sell any routers, but I sold the panel and battery to him without thinking I was going to sell it.

I bet I couldn't even ship this to my next door neighbor for less than $32 in shipping costs.

Limit 1.

Also the Ecoworthy panels are crap. I've got several. They don't even come close to rated specs. Would recommend spending a little more and getting Rich Solar, Newpowa or Renogy. There's some Renogy deals on Ali as well. You'll end up needing almost 1.5x the number of Ecoworthy panels because they inflate the panel ratings. If you price racking, that's the real cost. It's often as much as the panels in the end. Less racks and more panels is far cheaper than more racks and more panels. Take whatever Ecoworthy is telling you and estimate the actual max real world output will be about .65x and you won't hate yourself.

I've got the same River2 and get 90+ watts in ideal condition from a 100w Eco Worthy panel bought in '23...for 32 bucks Im thinking of getting another panel I can just leave outside year-round.

It's impressive how fast solar panels are dropping in price. In around 2022 when I was bought mine, the going rate was around a dollar a watt.

These look like the same ones I bought from that auction site two weeks ago for $45. I am getting 85 watts on a sunny day in fall. I am happy with them.

can you tell me what kind of voltage you're getting on a single panel? i'm going to hook up to a 48v system on my travel trailer, so planning on at least 4 panels if these panels really are indeed 18v.

The listing for my panel are 12v, so these must be different.

I get right at 175 watts out of my 2 panels on a perfectly clear and sunny day. These conditions dont happen often where I live but I can still normally get in the 130 to 150 range pretty consistently. For reference, I live in southern Idaho right at 6000 feet above sea level. I am very satisfied with these numbers.
