It is not going to work well with your other panels in either a parallel or series connection. In addition it will not be usable by itself for charging a 12V nominal battery of any type.
A clear case of "Ready, Fire, Aim!"
(If the output current of your panel is within 5% of the current of your other panels, you can can put it in series with those panel(s), as long as the device you are feeding will accept input power over a wide voltage range, i.e. MPPT input.)
