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?

I understand in cooler temps Voc will go up, but I was looking at going parallel, not series. And, if and when necessary, adding a third 100w panel.
And, yes, I asked because I wondered if the 12's would provide enough voltage for the mppt to work with. In hot weather, what kind of Voc would I be looking at from the 12's, and how much V is required to kick the controller into mppt mode?
My thinking is, with going paralleled, the amps will be there, without significant bucking. And I don't see me needing EQ type voltages in the summer, for two reasons, 1) temp compensation, 2) the batts should remain well topped up, so eq'ing should not be needed. So provided I can get say 14.6v on a hot day, I should be good to go.
BFL has pointed out previously, pwm does better in the heat, while mppt does better in the cold, but it's in the cold I need to max out every little watt. Does the mppt lose that much of an advantage in hot weather?
