MPPT vs PWM: which is better?

When to choose MPPT over PWM for higher yield and system size.

By Gavin Elliott7 min readUpdated 20 August 2025

Quick answer

MPPT controllers usually yield more energy with higher panel voltage and cold climates. PWM can be fine for small, budget systems.

How they work

MPPT finds the voltage/current point that maximises power. PWM clips voltage down to battery level.
