STEP 1 Check online to discover your home’s latitude. This is the angle at which you’ll mount your solar panel. STEP 2 Cut six pieces of plywood for the box. The lid should be slightly larger than the solar panel. Trim the top edges of the side, front, and back pieces to the appropriate angle. Cut the bottom to fit. STEP 3 Drill a hole in each side panel for airflow: one in the back panel for the controller and battery cords, and one in the lid for the solar panel’s cord. Then nail the wooden slats to the lid and mount the solar panel to it. Assemble the box with a hinge for the lid. STEP 4 Snip off the cigarette-lighter plug and solder the ¼-inch (6.35-mm) mono plug onto the Y adapter. Insert the mono plug into the controller’s 12-volt output. STEP 5 Connect all four power leads from the battery and the solar panel to the controller’s input terminals. Hook up the 15-amp DC panel meter to the controller’s input terminal for the panel. STEP 6 Test all connections with the meter. Connect the red wire with a female-terminal disconnect to the battery’s positive terminal, and connect the black wire to the negative terminal. STEP 7 Place the station in the sun with the solar panel pointed south (north if you’re in the southern hemisphere). Plug something in!
