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 ...

PT I don't get any special MPPT advantage that I have noticed during the shoulder hours or in low light compared with my PWM results. Both are poly panels if that matters.
Of course it is easy to confuse what is making the MPPT advantage you do get in the morning between the low battery voltage (as above shows) then and maybe thinking that is from the supposed low light advantage you hear about?
Anyway I have not seen anything like that, but I have not been everywhere and done everything either :)
BTW once again I have too much solar. I guess it is my hobby now, buying and selling the things. I might end up being just an MPPT guy! Horrors.
