Yet Another PWM vs MPPT Comparison Test
I was able to run a couple tests with blue sky at same time of year and location as my test from two years ago (flat, tilted, tracking results one) that : A. compares PWM with MPPT, and B. compares ...

The heart of a MPPT controller is a dc-dc converter with a variable voltage input that's controlled by a microprocessor of some sort. The controlled dc-dc converter forces the solar panels to operate at the optimum voltage-current combination for the current light conditions. It uses some sort of algorithm to find the optimum operating voltage for the panels, which changes as the light conditions change. The PWM controller doesn't have the capability to force the panels to operate at the optimum voltage-current combination.
