Choose a solar panel whose open circuit voltage matches the battery charging voltage. Meaning for a 12V battery you may choose a panel with 15V and that would produce maximum optimization of both the parameters.
For example, if the open circuit voltage of your solar panel is 20V and the battery to be charged is rated at 12V, and if you connect the two directly would cause the panel voltage to drop to the battery voltage, which would make things too inefficient.
Basic Components of a 12V Solar Charging System A basic photovoltaic (PV) solar electric panel system for 12V battery charging comprises a solar panel connected to a charge controller, connected in turn to the battery. PV Solar panels The amount of power that a PV solar panel provides is indicated by the wattage (W).
