If your two panels are putting out 18Vmp, then the maximal charging voltage will be ~36V, less than the bulk starting voltage you need. So, as Photowhit indicates, you''ll need 3 panels in series to bump up charging voltage to 54V. Then, an MPPT controller will transform the incoming raw solar to exactly the voltage the battery wants.
A "12 volt" commercial solar panel is usually rated about 17 to 18vDC which is a good match with a charge controller. Without a charge controller you may either over or under charge a battery. For your small system a low cost PWM type CC will work. But I would recommend sizing your panel wattage based on the battery Ah rating.

A 36-volt solar panel can be used to charge a 12-volt battery. A charge controller is used to regulate the volt output from the solar panel and step it down to the volt input used by the battery. Electrical systems with higher voltages experience fewer losses when moving electricity from one place to another.
Technically it is possible to use any solar panel to charge a 12V battery if the solar panel has the same or higher voltage. The main issues to consider are the capacity of the battery and the power rating of the solar panel.
You can use your 24V & 36V solar panels with your 12V battery. But the question is, should you? In this guide, we cover the basics of matching solar panels to a battery. On a side note! If you’re in need of a reliable and high-performance portable solar panel, We strongly recommend the Jackery SolarSaga 100W Portable Solar Panel (Amazon Link).
A solar charge controller is essential for charging a battery with a solar panel. It regulates the voltage and current flowing from the panels to the battery. When choosing a charge controller, consider the battery type, voltage compatibility, and the amperage of your solar panels.
So, for example, let's say you put two 18V 100W panels in series, which will give you ~5.5A at 36V. You could then wire one 36V panel parallel to the string of two 18volters because they are both putting out the same voltage. How many watts is that 36V panel? Let's say for example that it is a 300W panel putting out 8.33A at 36V.
Check Voltage Output: Ensure the solar panel produces enough voltage to charge your 12-volt battery, typically around 18 volts. Gather Necessary Components: Collect a solar panel, charge controller, 12-volt battery, and appropriate wiring. Install the Charge Controller: Connect the charge controller between the solar panel and the battery.
