And with partially shaded conditions I'm ahead with serial panels and MPPT because of their bypass diodes. I've posted several threads on this effect.
Lots of good advice above. My very good MPPT solar was the same price as a PWM solar system. Why? Very simple as the solar panel cost per watt for 24V panels is less than 12V panels. This will continue in the future as the volume production is for homes/business and they don't use 12V panels.
The 24V panels are larger but once one begins to consider installing the panels higher off the roof that becomes a non issue.
