The very popular 24V panels with 60 cells are about 30V+. Parallel 60 cell panels do not match up very well with 24V batteries which need 29.6V for bulk charging. This is not analogous to 12V panels which are 36 cells and 18V for 14.8V bulk charging.
2 12V panels in series or 72 cell panels would be much better.
I posted about testing a 24v 60 cell panel on 24v battery bank in 2014 was it? Anyway, I was able to get the batteries to 30 volts and keep them there, but that was it, no higher as needed for equalizing.
So you can indeed recharge a 24v bank with a 60 cell 24v panel, but that's all.
12v panels in series means your total Voc goes way up, which means you need a controller that can hack that many Vocs--some are only good for 50Voc or less. Some others are good for 100Voc or more, but these seem to cost more-- haven't looked at all the pricing for that.
