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?

Listen, when it comes to MPPT vs PWM, Mono vs poly vs amorphous, 12v vs 24v, etc etc etc. Don't get hung up on one thing because for every advantage, there is a disadvantage to deal with.
BLF brings up the heat issue with MPPT. As Paul Harvey use to say, this is the rest of the story.
PWM cost you watts early on in the charging process. The rated watts of a 12v panel is at a higher voltage than your battery will be early on, so you will get the watts available at that voltage, not the rated voltage. MPPT doesn't waste the power early on.
