Um, Given that the open circuit voltage listed is 22.5 volts, you reach the limit at 26 panels in series. The 27th puts you over 600 volts.
The "real" limit is the total Voc limit rating of your solar controller, which can be say 100 volts at 77F/25C. So you can string maybe four at 22.5 each in series. But then remember that Voc goes up with colder temps (and down with higher temps) so in the cold you could fry your controller if you are near the limit for 25C.
