Solar switch concept

This is a power usage concept the building is only to hold the mechanism. When you dload this you need to do a couple of things to get it working.

1. Make sure the bottom of the arm holding the solar panel is in the ground and not on a grid.

2. delete the 2 white blocks connecting the solar panal arm to the building.

The solar arm should now be free standing beside the building and not connected to any grids.

If you have done this correctly the lights in the building will turn on at night and off at sunrise.
