Any tech reason (electrical/electronic) why the solar panels could not be installed up higher, perhaps above the cameras in order to defy direct vandalism of the panels?
I can see that a ferocious wind can push on them and the taller the mast the more leverage they'd have but just a little would help. The heavy batteries and charge equipment in an secure, armored box at the bottom (as show) PLUS perhaps some anchors could help prevent tipping by the wind.
Could a wind-driven charger be added up there to help with those overcast days that don't recharge the batteries well?
The panels when placed above the cameras could help shelter them from direct rain and sun, perhaps extending their life.
