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 ...

What you say is correct. But it doesn't matter. 12V panels are specifically designed for pwm use. The panel spec is optimized to provide maximum efficiency when operating in pwm mode. The performance difference is less than 10%. On hot days the difference is negligible.

The PWM controller doesn't have the capability to force the panels to operate at the optimum voltage-current combination.
