because of China, they are way ahead in the solar/battery/energy market. They can now produce in massive scale so the price is extremely competitive. Before some dumbs starting to argue, the batteries in your phone, tablet, watch, and almost all other electronics except US electric cars, are all made in China since day 1. US government won't allow them to officially open a store or sales department here, because they will just destroy all the farking expensive non sense US companies. Like the solar roof system here in US, can cost $20K-$40K easily, and the same system in my grandma's house in China is like 10x cheaper......

Surprised this took so long to show up. If you're buying at least 2 you can use the 10 off codes for a better deal (USDEAL10 and then USAA10). Bought 2 and 2 yesterday for super cheap.

How come? You're buying a Chinese made product from a Chinese retailer, do you think it suddenly turns into a better product if you buy it from Amazon?
The few times I've ordered from them (small electronics) they came way better packaged than anything I've ordered from amazon, not to mention Amazon's customer service is becoming a joke, im still battling an order from 6 months ago where they sent me the wrong item then charged me again because the item I returned wasn't what l ordered. Uh yeah thats the problem.

Quote from informed-consumer :
kind of a bastard voltage , yes? what application does this voltage lend itself to?
The are like 23 ish volts in actuality. But it doesn't really matter what voltage it is. Solar panels don't power things with their voltage directly. Even ones that say "12v" or "24v" aren't ones you would be hooking straight up to a battery or powering devices. You'll be hooked up to a charge controller always which will put out the voltage your battery needs. Otherwise you're connecting it to a power station which will do the same thing for it's own battery.

I wish it is 12V
It is for 12V, you just need a charge controller (preferably MPPT).

I have never and will never buy anything from AliExpress. I wish there was a way to block them on Slickdeals.
I was going to ask if Ali was any good as a trust worthy site.
I already ignore anything from temu and there deceptive listing, thinking your getting one thing but in the fine print it totally something else.

Lucky I never experienced it as I prefer to experience this issue through my neighbor who comes to me and complains about their latest buy temu and then telling me that it was not what they thought they were getting. And then goes on how difficult to impossible to get a refund.

Just received mine. Good quality, packed well. Getting around 60 to 70 watts. The sun isn't hitting hard though. Lots of clouds. Thanks OP, this is a nice deal. Receiving them in 2 days is actually faster than Amazon! Lol

I'm curious what the argument for getting 100w vs higher wattage is. Obviously the price is cheap, but are you just having to have significantly more surface area for the same wattage? I guess I'm wondering if there are any pluses to lower wattage panels.

ELI5, what can you do with one of these? I live in an apartment with a balcony and good sunlight. What's a practical use for one of these? And are they easy to use? Like can I just plug something into it?
