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?

Those 100's I'm looking at are rated at 47C (nominal cell temp).
And the blurb says 'point three eight percent', .38%, so wouldn't that be .0038? So, 47 x .0038 = .18 + 21.92 = 22.1v
In your case, 25 x .36 = 9v, not .9
and 25 x .0036 = .09 + 21.9 = 21.99v,
Or is the blurb wrong, and should say 3.8%, not 0.38%?
So, ~ 23.7v at 0C.
Now that I read it with my eyes open, it does say -0.36%/C
Mine gives ratings at STC not "nominal" by which they give themselves lower expectations than STC for output. I always got STC rated Isc from my 12s so that is what I expect.
Whatever controller you get, make sure it has adjustable high set point. IMO ignore temp comp except for long term storage battery Float. While camping you can play with the Vabs if especially hot or cold out.
