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.

A 24 volt solar system uses multiple solar panels wired in series to produce a higher DC voltage output around 24V. This 24V DC electricity is stored in batteries and converted by inverters to power 24V appliances and equipment.
