Hi,
This is / will be a solar tracker for a 100 watt solar panel.
It was a folding panel made rigid. I may change it for a 120 watt.
This fence is south facing but, the sun hits the fence at 10:30 in the morning and moves down the fence over a few hours leaving the left section in the shade by 2pm, hence the linear rail.
By 2pm the sun hits the west facing wall where there is a 120 watt panel.
I’m going to add another gantry plate with 4 more wheels.
Could also be used as a camera slider
