MPPT vs PWM Solar Charge Controllers – The Decision Is Clear

So you won''t get 18V all day. But still, at the end of the day an MPPT charge controller will have harvested more power from the solar array because it is always tracking the highest power point whether it''s 18V, 15V or 13V. In a small setup like a camper van, the higher efficiency of an MPPT charge controller doesn''t make much difference.
