Eco-Worthy 12v solar panels, Now drifting to... mono vs poly
When I search here, the only Ecoworthy results I get are for their controllers. Does anyone have any experience with their 12v panels?

Didja search ebay on 100 watt 12v solar panel,.....or any other wattage. Their all the same good quality, and all perform very good.
Windy nation, Ecoworthy, and a couple more too, all about the same price too. Most buy the poly panels over the mono, why I don't know.

I probably started the poly over mono thing with my side by side testing. All of the advertising say that monos are more efficient because they reach their rated output with less footprint. Great for a grid tied system where you have a automatic back up. Let even light clouds come in and the Voc and Isc of a mono drops like a rock. In heavier clouds my 220w mono wont even wake up the controller.
My 245w monos will drop from 17a to under 3a with the lightest cloud cover. In the same light my 230w poly easily puts out 8a. Even in cloud cover think enough that you can't tell where the sun is, the poly puts out 4a. That's not enough to keep up with our uses, but was enough to keep us off the generator until the sun came back a few days later.
So the hype is right but just not for our situation
