Step-by-Step
Build the case
To make a cheap, eco-friendly case, we glued up bamboo flooring scraps (bamboo is fast-growing and renewable). Cut holes in the box for airflow and easy carrying, and build frames to hold the DC charger controller and the battery.
Add the panel
Attach the solar panel at an angle roughly equal to your latitude for optimum charging (go to homemadeenergy to find yours). Add a tilt bracket for additional adjustability. Leave space underneath both the panel and the controller for airflow.
Wire it up
Snip off the cigarette-lighter plug and solder the quarter-inch mono plug onto the "Y" adapter. Insert the mono plug into the 12-volt output outlet on the controller. Connect all four power leads from the battery and the solar panel to the controller's input terminals. Hook up the meter to the controller's input terminal for the solar panel. For more power, attach additional solar panels, and add extra batteries-but don't exceed the 12-volt rating of the controller.
Connect the battery
Test all connections with a volt-
meter before attaching the battery.
Connect the red wire with a female-
terminal disconnect to the battery's
positive (+) terminal, and connect the black wire to the negative (â€) terminal. Place the station in the sun, and plug something in.
