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 Robika :

I've ordered many things from AliExpress and only once got something other than what I ordered. I ordered a mini pc and the processor was not what they advertised. I contacted the retailer with a picture showing that they sent me the wrong one and they asked if I wanted to return or accept 50% refund. 50% of what I paid was a massive bargain for what I got so I went with the refund. 2 days later 50% back in my account.

I also feel much more comfortable ordering from AliExpress when it's being shipped from the US vs China. Also, I look at the reviews, there are many reputable retailers on there.

Hey, you do you. But to say that they should be blocked from SD is pretty silly, no one is forcing you to order from AliExpress.
I've been flat out ripped off by AliExpress. I'll still order from them but they won't hesitate to burn you.

Can't get USDEAL10 to work. "for security reasons your request can't currently be processed" I must be hacking the mainframe of AliExpress or something. XD
Yeah I can't use AliExpress for that reason but if you turn off your VPN or ad blocker you're usually less security risk with them.

I've had this exact panel for years. It's been tossed around and still works fine.

I've purchased an item from the Aliexpress once. They shipped it quickly, but then the tracking showed it was in transit in a city for like 2 weeks. It was never updated for 2 weeks. I assumed it was lost. I contacted the Aliexpress but they never refunded me because the tracking showed "in transit". After another 2 weeks, I just disputed with my credit card and never bought another from them.

I am currently dealing with EcoWorthy through AliExpress, and this has been, without question, the worst customer service experience I have had in over 50 years. What should have been a simple return has turned into an ongoing, frustrating ordeal. The batteries I purchased do not fit, yet after more than a week, I am still being given the runaround with no resolution in sight. The level of inefficiency, lack of accountability, and overall disregard for the customer is frankly unacceptable. Based on this experience, I strongly caution anyone considering a purchase to think twice. I would not consider buying from this seller again under any circumstances.

Ships from the united states. If this was 6 months from now after I relocated, I'd probably be buying 100 panels.

Under 4k delivered for 10kW ... not sure how you'd beat a deal like that. (yes, you need mounting, controllers, etc.)

I have never and will never buy anything from AliExpress. I wish there was a way to block them on Slickdeals.
do what I do with the promoters I've blacklisted from this site (mostly amazon pushers). Ask chatgpt how to block the posts that have aliexpress and they won't bother you anymore. I've used AliExpress or AliBaba with great success (most of it junk but ordered knowingly).

Just an fyi, those are plastic. Plastic solar is not great. They get a white film on them from the sun and massively lose efficiency. All my plastic panel solar products are in the trash. My glass ones go 10 years with a battery change.

With 2, is there a way to combine the charging cable into 1?
Looks like mc4 connectors. Pretty easy to do. You can serially connect the panels on one +/- pair of connectors and then connect the other two ends to your controller device, if it's under the maxV your controller accepts. If the total voltage of two in serial (add each panel's maxV together) is higher than your controller can take, you may need to look into parallel connections instead, this might require more adapters.

I got a few of their 130 watt "plastic" panels. I keep them in my garage to pull out for power outages. Cheaper than portable panels and easier to carrier than the rigid.
That said, I do have a few rigid and portable panels too.
