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?

"If you start with a 12v panel and PWM, you can add more 12v panels and then choose to stay 12v in parallel with PWM or put them in series as 24 or more and go MPPT."
That's actually how I was considering it. With 12v you can always series/parallel up, but you can't go down from 24v.
But what's the deal with pwm and mppt then? There are 12v kits with mppt. Is pwm sufficient when dealing with lower amps?
