Ok, there is a recent thread out there MPPT vs. PWM and some post were a little confusing to me. Instead of hijacking his thread I started a new one. My set up is two 208 watt Sony panels with 28....

Amplified and correct, Mex.
2*208W + PWM = waste of the roof space.
I would disagree.
Your conclusion is not well informed.
24V panel with PWM and 12V bank is inefficient, few people said this already. You will be getting less than a half of what you would with 12V panels or with MPPT. I don't know how to make this more clear.
Just a blue sky thought as we slowly drag out the details from him.
