This project shows how to build a 63W solar panel using plain materials. It will guide you through everything from building the frame to soldering the solar cells. The frame is build of plywood and solar cells is better to be soldered using a low wattage soldering iron. Finally you add the plexiglass and your panel is ready. Check construction details on the link below.

This project is used for charging sealed lead-acid batteries with a solar panel in small and portable applications. The charger will stop charging once a pre-set voltage (temperature compensated) has been reached, and resume charging when the voltage has dropped off. The load is disconnected when the battery voltage drops below 11V and reconnected when it gets back to 12.5V.
