PWM vs MPPT Charge Controllers

MPPT Advantages:

Up to more 10% solar yield (summer) (typically 5%)

Up to more 40% solar yield (winter) (typically 25-30%)

Up to more 45% solar yield on cloudy and rainny days

They accept a higher input voltage, able to accept several panels in series (reducing losses and cable size), and different voltage panels can be used: example, 24v panels can be used on a 12v system

PWM advantages:

Lower dimension and weight

Way cheaper
