A 12 volt panel has maximum power at around 17 volts so will need a minimum of 2 in series in a 24 volt system. There is no technical disadvantage but larger domestic sized 24 volt panels are cost effective.

Determine the Solar Panel Output: A 100-watt solar panel typically produces about 80 watts in optimal conditions. Calculate Watt-Hours Needed: Multiply the amp-hour rating by the battery voltage (100Ah x 12V = 1,200 watt-hours).
