I tested their bifacial panels compared to another panel. At the same day/time/angle (not laboratory ideal conditions obviously) the other panels output 82W and the ecoworthy output 58W. That makes them 70% as good as comparable panels and may only output 70W in idea conditions (very rough estimate). Only buy these if you consider 70W panels good for this price. Personally I'm mad at the deceptive advertising and won't buy any more ecoworthy.

What was the other brand and how much did it cost? What was the price/watt comparison between the two? $32 still seems pretty good for 58w, I paid $20 for two 20w panels and they don't give me 30w combined even in ideal conditions lol.

The specs on the 12v and 18v panels are exactly the same (down to the weight), so one of them is wrong and falsely copied over

FWIW my bifacial panel just arrived today but I havent had a chance to test it

Do they just expect you to raise these over a reflective surface when they advertise bifacials now?

The other panels came with a Kickstarter, solarpivotpower. Different use-case, they're flexible panels custom-made for their robot. They're selling them separate from their robot arm thingy for $200, but it's currently a $100 upgrade for the robot. Since they're a new company and this is a new product I was expecting them to be underpowered. I also tested the Gendome panels available right now. They advertise 200W and got 140W at the same time, so relatively speaking they would have been 70W on this day/time/angle vs Ecoworthy's 58W. The Gendome also have several bad reviews because they're underpowered, so the Ecoworthy outputs noticeably less power than a panel that is known for being underpowered.

Basically price/watt/value is up to you and your use-case, just know that the advertised wattage is inaccurate.

you have to check the spec on your jackery on how much volt, and amp is allowed. Jackery 2000v2 only allow for 400w. I would imagine it's around there. My bluetti says 1000W of solar, but I'm able to at most get 600W, because of their 60v, 20Amp limitation on their input.

Can this be used to keep a car battery topped up on a trailer that sits? Still need a charge controller?

I have a single Eco Worthy panel with the same specs as this listing. I have been able to get up to 90 watts in full sun with no shade on the panel. This is fall sun too. I cant wait to try it in the summer. My smaller power station recharges so fast when the wattage is above 70. I am happy with the panel.

They are the same model number so no difference. The Jackey solar input allows 16V-60V and the MPP of the panel is 19.5V so it should work. If you are using it as a portable, consider a folding panel: https://slickdeals.net/f/18833728-eco-worthy-100w-18v-portable-foldable-solar-panel-w-8-in-1-connector-adjustable-stand-49-99-free-shipping?src=SiteSearch

You are missing the point.

Don't advertise something your product is not capable of.

The 12v doesn't appear to be bifacial while the 18v is so there's another difference between the two.
