I'm getting 2 more to complete 2 parallel strings of 48V.
Better deal if you buy 2 and use code CDUS08 for $8 off.
And yes, I trust AliExpress, like I said I have 6 panels from them already and they all work perfectly fine. Only mentioning for those that are on the fence about buying from AE, cuz I know there are a lot of AE haters out there. And no, I'm not a shill.
Community Reviews
Eco-Worthy's 100W monocrystalline panel comes across as a very cheap option for backup power, van setups, sheds, and other small solar projects. Real-world reports range from about 75 percent of rated output to roughly 85 to 93 watts in good sun, with some setups lasting years without issues and shipping arriving quickly from the US. The panels are also described as bulky for camping and not ideal for whole-house systems. A few comments flag cracked glass, compatibility checks, and the need to match voltage and wiring carefully.

The DARAN deal (now dead) a couple a weeks ago would have worked well https://slickdeals.net/f/19356804
If I buy one panel for $31 (just one panel), what can I do with it? What are the practical use cases?
Thanks.
These are Model Number: L02M100TM-1 Panels and are going for 69.99$ plus shipping on the eco worthy main site..

Look in the mirror and tell me light doesn't reflect off things!
He was talking about 4 panels..I was talking about 4 panels with different series/parallel combinations..
No for 4 panels in series the voltage is about 90volts 22.7 X 4=90.8 OC
If in a series/parallel combination then 2 in series is 45.v then paralleled with the other two panels that are in series the voltage will still be 45.5 but the current will double...
but you have in effect lowered you voltage ceiling but upped you current amount as the current is then doubled...
As long as you stay within the voltage/current limitations of the load device you can series or parallel or combinations of both..
Series voltage is additive current remains the same..
Parallel voltage remains the same current adds up..
You are creating strings of panels in a way that stays within the boundries of the load device to safely protect the load device ..

Its Total voltage reduction by paralleling/series all 4 panels ... it is not making a panel itself lose half its voltage..
