I wonder how difficult it would be to make a heating system directly powered by solar panels. It doesn’t have to be enough heat to make a person comfortable in a t-shirt, but just enough to allow normal battery operation.
I’m sure that depends on a lot of factors like shed insulation/wall facing direction, etc, and burying the battery bank would probably be more effective.



The white brick at the bottom is for detecting large objects (cars) and is either controlling a traffic signal, or is being used to count traffic going through that spot.
An intersection near me uses them to switch the lights at an intersection where traffic almost never comes from, so a timed light is unnecessary, but important traffic still comes from that direction.
