Other Parts Discussed in Thread: TIDA-00120
In both TIDA-010042 and TIDA-00120, Q1 is oriented with the body diode conducting in the direction of current flow. It seems then that Q1 is wholly ineffective as a switch, and merely decreases the series voltage drop with the solar panel when toggled. Can you confirm that this is the case?
Additionally, if Q1 was oriented in the opposite direction and thus actually able to block current flow, it would seem to truly float the panel from system ground, making meaningful voltage measurements impossible.
Am I missing something?
