Additional steps taken:

Enabled Atmega328P's BOD at 1.8V level to enable usage at 3.3V or lower voltage
Use of 5V LDO between solar panel and supercaps
Supercaps in series with 5.4V (only 5V max used) and 5F as result
Use of 3.3V LDO between solar panel and supercaps
Test with renewed hardware using a standard blink sketch
