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?

RE; Series vs. Parallel,
Until now, I have only considered going parallel. So would there be any advantage, in my situation, by going in series?
So, two 100w panels thru a 20a pwm...
I'm thinking less current (say 5a in series vs. 10a in parallel) running thru the wiring from panels to controller, and therefore less voltage drop... so perhaps, overall, a little bit better? But at such low currents, either way, is there really any significant advantage? I'm thinking, no.
And I would think 50' of 10ga cable would easily handle 10 amps.
Moreover, going series would limit my choices of pwm, seeing as I would need one that can handle the higher Voc. So, again, no advantage.
Just like comparing the mppt with the pwm. On Salvo's chart, yes there was a gain of about 11% overall, but 11% of only about 6 a/h average. So with two 100w panels, perhaps a gain of about 13 Ah's over ten hours. And on a shorter (winter's) day, perhaps only 5Ah's over 5 hours.
On a small solar set-up, it all seems rather irrelevant.
