mppt or pwm An opinion from Victron
Hi all, Victron, which makes high quality equipment, has charge controllers. At the end of an overview they give their description of the differences between PWM and MPPT. They do not support it wi...

No, nothing significant is wasted. You forgot one key element to the equation: TEMPERATURE. It kills mppt performance. Go read that white paper again. It's very good.
The 36-cell panel was specifically designed for pwm use. Very little power is wasted at normal operating temperature. That's why there's only a 5 to 10% performance gain of mppt over pwm.

7amps at 14v is 98 watts, with out MPPT you loose the rest of the power, it is simply not converted... it is chopped off and eliminated... wasted ..not used
PWM is fine for panels with a 16v output, but wastes power on larger panels
