Still Don't Get It (Solar)
What will charge 2 6v golf cart batteries better, a single 270 watt high voltage panel with mppt or two 135 watt 12v panels (parallel) with PWM and why???? Thanks. Gman

Yep, IMO its still a bit cheaper, no matter how you want to misrepresent it !!

Hi,
Panels requiring MPPT controllers are as low as 30 cents a watt and are fairly often on sale at $0.76 per watt. Nominal 12 volt panels are almost always well over the $1.00 per mark. I don't call that "a bit cheaper".
The controller is the key.RJsfishin wrote:
Cost difference ?????? Its a wash,....panels are a bit cheaper per watt. controllers are NOT.
