Used Panels

I have purchased 2 used solar panels from the CSX Railroad.  They measure about 18 x 25 inches.  They each have a number 12 stranded wire coming out a waterproof box.  All parts look stainless steel.  I want to try and use these in my barn to run a water pump.  

I know nothing about solar.  I have some limited electronics background.  I connected the 2 panels in parallel and have 3.39 volts on my volt meter when the panels are laid in the sun on my back porch.  What do I need to do to get 12 volts to a battery?  Where can I get some help?

Re: Used Panels

seems like maybe one or both of the panels may be damaged. Try taking individual voltage readings and see if one of them reads 12-18 volts.
