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 caotico :
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.
What are you talking about? This is actually smaller than most 100w panels which are 41x23. If you go for bigger wattage the panels get huge

Quote from PurpleScent2237 :
more and more AliExpress ads
I'd usually take it over Amazon. AliExpress Choice/US-warehouse is Aliexpress-fulfillment just like Amazon fulfillment. People buying from shady sellers directly on Aliexpress isn't much different than buying from shady sellers on Amazon - both are simple marketplaces with a lot of counterfeit goods, and few reputable name brands (same with Walmart, Newegg, eBay, whatever other marketplaces). The main difference is that someone else typically buys the things from China, puts them in Amazon warehouses, and sells the same generically-branded thing for a markup. Sometimes that markup is 2-3x.

Aliexpress using Choice shipping also provides return labels for goods, and something like 5 items per month. If it's more than that, Amazon or elsewhere, that's likely return abuse by the end user.

I can't even take Amazon returns to a Locker+ anymore for things that are fine, but like a general store return. Amazon shut this down about a year ago. Amazon offers nothing to me now days other than higher prices, and similar return policies.

It's just the way things are now days - the niceties of Amazon from 15-20 years ago don't exist today. May as well cut out the overpriced middleman, or otherwise shop local B&M.

I used to feel this way, but I gave them a shot the last few months and have gotten some incredible deals on LEDs, connectors, wiring and other things that would have cost me 4-10x as much anywhere else. Fast shipping, too.
