The solar panel converts the sun’s energy into DC electricity and this electricity charges the battery. The battery stores the electricity, similar to a water tank storing water. This battery power may be used at any time to operate DC powered devices connected to the battery. To increase the battery service life, a solar controller is used to prevent the solar panels from overcharging the batteries. This is process is managed by the Solar Charge Controller included in this kit. See Figure 2-A (below) and 2-B (on following page) for solar system examples.
