Note: When the voltage of your solar panel don't satisfy your storage battery, you can take two or more same solar panels together in series.
Such as,two 5.5v solar panel take together in series, so its voltage is 11V. when the voltage of solar panel satisfy your storage battery. In order to Speed up the rate of charge, you can take two or more same solar panel together parallel connection.
