Every figure below starts from the datasheet: 21.50 V, 18.40 V, Isc 12.40 A at 25 °C, and a Voc temperature coefficient of −0.25 % per °C. That coefficient means the open-circuit voltage climbs 13.8 % by −30 °C, to 24.5 V per panel.
Read the cold column. On a 120 V controller this panel fits 5 in series at 25 °C but only 4 at −30 °C, so a string wired from the label number fails the first hard frost.
Where you install it changes the answer on the same 100 V controller: 4 in series in Honolulu, Key West, Fort Lauderdale, Miami and 312 more; 3 in series in West Yellowstone and Fairbanks, using each city's design low.
For wiring, one string carries 12.40 A of short-circuit current, so the cable and any string fuse are sized for 19.3 A (Isc × 1.56, NEC 690.8). Because the drop is measured against string voltage, not 12 V, the cable stays thin: 2 in series over 5 m need 12 (1.7 % drop at 36.8 V) and 4 in series over 10 m need 12 AWG (1.7 % drop at 73.6 V).
