Today we added a fourth solar panel for the purpose of improving early day battery charging.
The other three panels are aimed due south re-tilted at 26 degrees for maximum December 22 output at noon. This new panel is aimed due east for the first sun of the morning tilted to obtain peak output at 8 am. We often want to operate just after dawn when the batteries are at their lowest. This panel should fill in the gap until the main panels are getting sun.
