Attach the solar panel onto the metal plate.

Using screws and a screw driver, screw the solar panel into these holes. Now that the solar panel is attached to the metal plate, attach the metal plate onto the lid of the enclosure.

Note: the tall side of the metal plate should be on the same side of the enclosure as the holes for the ultrasonic sensor and cable glands.

The screws and nuts should be screwed in this matter in the holes on the sides of the box lid (meaning the nut is on the outside).
