I have a fence that gets absolutely blasted with High Grade Texas Sunlight. It shortens the fence’s effective life by years — this idea is brilliant. Now I just gotta price out 80 sq m of solar panels.
EDIT: The fence gets at least 4 hours of direct sun in the winter; up to 7 in the summer. I can easily install 10KW of panels. I don’t have any way to store the power. I suppose I could build a giant Tesla coil and zap the neighbor’s dog?
You can push excess power into the grid. It will reduce / reverse your electricity bill. Look into local regulations.
