Re: Solar panels stainless steel mounted vs soft panels

You don't mention anything about what kind of regulator you use (used) with your solar setup, if you used one at all.
You imply that panels in series are not efficient, but I'm guessing your 2 x 18V (nominal 12V) panels in series were connected directly to the battery bank, and no that is not efficient.
If you now have 36V panels, wired them in series and used a MPPT type controller/regulator, then that is very efficient.
But if you just wired them in parallel directly to the battery and don't have a MPPT conttroller/regulator you will be missing out on a lot.
