The electrical energy generated by solar panels must be stored by batteries. Without batteries, the electrical energy generated by solar panels cannot be used the next day. Second, it depends on the type of solar panels you have. the load connected? A solar panel with 36 silicon wafers will generate a voltage of around 17.5V. If stored in a battery, it depends on your light board, battery and load settings.
