There is a special component that you have to include in your construction when you build solar panels at home and that’s a blocking diode. This diode will prevent your batteries from getting depleted during the night when the solar panels isn’t charging them. If you don’t have this type of battery you will see that when the solar panels aren’t charging your batteries, the current will go the other way and power the solar panels instead. You don’t want this to happen because you lose a lot of money for the electricity being lost. It’s easily fixed with a blocking diode and you can buy this at your hardware store.
