What Solar Panel Size Do I Need to Charge a 48V Battery?

A 100 watt solar panel can provide 500 watts on a clear, sunny day, but even then it would take 10 days. And it is unlikely the panel can give supply 100 watts an hour during the entire period. With 48V batteries you should not settle for anything less than a 300 watt solar panel. Either 3 x 350W or 4 x 300W solar array will do.
