Every figure below starts from the datasheet: 45.50 V, 37.00 V, Isc 9.34 A at 25 °C, and a Voc temperature coefficient of −0.31 % per °C. That coefficient means the open-circuit voltage climbs 16.9 % by −30 °C, to 53.2 V per panel.
Read the cold column. On a 50 V controller this panel fits 1 in series at 25 °C but only none 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: 2 in series in Honolulu, Key West, Fort Lauderdale, Miami and 53 more; 1 in series in Modesto, Santa Clarita, Henderson, Las Vegas and 257 more, using each city's design low.
For wiring, one string carries 9.34 A of short-circuit current, so the cable and any string fuse are sized for 14.6 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 16 (1.6 % drop at 74.0 V) and 4 in series over 10 m need 16 AWG (1.6 % drop at 148.0 V).

How this page was computed
Series count = controller limit ÷ (Voc × (1 + coefficient × (T − 25))), rounded down. PV cable: ampacity from ABYC E-11 against Isc × 1.56, voltage drop against string Vmp with a 2 % limit.
