Eight 6 volt 300a/h batteries is the equivilent of ONE 48V battery with 300a/h's. So...you would have 150a/h's at 48V to work with to get to 50% discharge and need re-charging.
Most 100W panels provide 17V output and approximately 5.9 amps so you would be providing about 24amps at 17V with 4 panels BEFORE regulation to 48V...and this works out to 2.2amps or so at 48 volts with a good regulator. Figuring 5 hours of peak equivilent sunlight a day and some conversion losses this would allow you to replace about 10amphours at 48V back into your batteries.
