Don't do series unless....
In Response To: Question on series vs parallel connection of two solar panels ()
you have an MPPT charge controller. Series doubles the voltage. Your charge controller has to match the solar panel output to the charging profile. Only an MPPT controller can handle the voltage difference.
25 feet is a long haul for solar - big voltage drop unless you have heavy enough wiring. Be sure to get the wire size right or you will loose a lot power.
