I've gone through two bq24074 to where it just stops charging the battery. Monitoring the LIPO pin, the voltage oscillates between 0 and 4VDC. I suspect that it is because the panel is outputting more than 1A thus frying the IC. I have since cut the 1A jumper and soldered the 1.5A. This needs to be verified by reading the current of the panel.
The two that died also had the optional capacitor installed. This may also be a culprit. Third one does not have a capacitor.
