$begingroup$ A simple 2.5V zener diode regulator would probably be as effective as anything. If you a blocking diode as well to prevent current flowing back into the panel then you will be pretty much set.

voltage regulator for solar panel 12 V
Your 12 volt solar panel will have a diode in series with it to stop voltage feeding back through the solar panel. So there is a 0.7 volt loss already, so you will get 11.3 volts from the panel. You should design for at least 50% higher voltage that your battery and then let the charge controller take care of matching the voltages.
