Time to start looking at solar.
so got up on the roof yesterday and measured everything up. so what I end up with is basicly 4 spots I can put a solar panel.
so drivers side front is 56" x 32" rear is 72" x 44" pasenger side f...

Panels in parallel have to have same voltage. Panels in series have to have the same wattage. Batteries in parallel have to have same voltage and wattage. Batteries in series have to have same wattage. Panels and batteries get confused as how to combine them.
Demonstration of Series and Parallel
According to this guys demonstration, if you have different size or rated panels and voltage, you will get better results in Series. Also the larger the panels in an array, The greater effect an oddball lessor panel will have. If the panels have close to the same voltage, you're better off paralleling them together. Watts isn't a measure when combining panels. Watts output is the measured result you get when testing the result of whichever combination you use. Rule is, close voltage in Parallel, and close amperage in Series. Wattage is the final result measuring voltage out times amperage out = wattage produced. Yes, batteries you want to match to the same model as the existing units. Different size batteries will discharge from Larger to smaller batteries in the connection. You especially do not mix different battery types with different ambient voltages, Lead Acid 12.6, AGM 12.8, LI 13.2.
