if you are interested in other type of calculations check them here Solar Panel Installations You don't want to use 12v to charge, you can certainly use the 12v panel and convert it to 18v. You'll lose charge current but you won't destroy the battery by under-volting.
It is possible to charge the battery by connecting the output of the solar panel directly to the terminals of the battery. However, if you are not carefully monitoring the voltage of the battery, then you run the risk of over charging it. This is why you usually want to use a charge controller.
Solar power is a great way to get electricity out to a remote project site. One simple way to do this is to use a solar panel to charge the batteries of your cordless power tools. In this project, I am going to show you several ways that you can do that.
"12V panel" means 18 volts. If it is designed to work with 12V panels it will work with your panel. Note that this inverter requires a battery. That inverter needs batteries, a charge controller in addition to the solar panels.
But in a typical solar system, the battery stays connected and the voltage will drop as the power is used. If your battery has a different operating voltage, you can change the voltage setting of the charge controller by using different values for the resistors.
The panel needs to have an open-circuit voltage (Voltage measured with no load) that it higher than the voltage of the battery when it is fully charged. You can find the open-circuit voltage of the panel by connecting your multimeter directly to the panel when in bright sunlight.
