Ive used this ecoworthy 20 amp model MPPT with a 280w - 38 volt panel.
IMO start with this. Its cheap and works. Accepts up to 50 volts and 300 watts of solar.
IMO upgrade to a larger panel and use this. It will serve you well for a few years.

A panel like this is a nice start.. Hook both panels in series to get close to max the voltage of controller. That controller will take the extra volts and turn them into amps..

This shows how mppt can turn 5.7 amps from my two panels @ 59 volts to 28 amps charging @ 12.7 volts. Although this is a 40 amp mppt and 560 watts of solar.
