just for completeness... yes, temperature drift of solar panel (so MPP voltage) can be compensated by the transistor in the input-voltage-regulation-loop, at least if forward voltage, temp. coeff. and temp. diff. are the same for that transistor and the panel (which is not the case for the real application, unless I hand-pick the transistor and couple it closely to the panel):
