How to size an RV solar system
To size an RV solar system, first work out how much energy you actually use in a day by listing each appliance, its power draw and how long it runs.

MPPT controllers convert surplus panel voltage into additional charging current, so they harvest roughly 10–30% more energy than PWM in cold or partially shaded conditions, and they are the right choice for arrays above about 200W or systems running at 24V and above.

LiFePO4 is the better choice for most RV installations because you can use about 90% of its rated capacity against roughly 50% for AGM, it lasts several thousand charge cycles rather than a few hundred, and it weighs substantially less for the same usable energy.
