Been looking for one to trickle charge a hardly driven car 12V battery
The MPPT can really help if your not in always direct sunlight like shaded or sometimes shaded areas, colder environments where where panels operate at higher voltage, or when the panel may operate at higher voltage than the battery.
Even a 20W panel using an optimized MPPT controller will out perform a 25W panel with PWM controller

$32 total after 20% discount and includes both panel and MPPT controller

For this price it's a no brainer.... Pwm or not. You can always upgrade and get a mppt controller if so so desired.
