Every figure below starts from the datasheet: 22.00 V, 18.00 V, Isc 12.50 A at 25 °C, and a Voc temperature coefficient of −0.27 % per °C. That coefficient means the open-circuit voltage climbs 14.9 % by −30 °C, to 25.3 V per panel.

Read the cold column. On a 25 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: 4 in series in Honolulu, Key West, Fort Lauderdale, Miami and 226 more; 3 in series in Toledo, Flagstaff, Williams, Ketchum and 84 more, using each city's design low.

For wiring, one string carries 12.50 A of short-circuit current, so the cable and any string fuse are sized for 19.5 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 36.0 V) and 4 in series over 10 m need 12 AWG (1.7 % drop at 72.0 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.

The formulas are the same open engine the checker runs; the methodology page lists every constant.

These results are for reference. Wiring must be installed by a qualified electrician. Mobile installations follow ABYC E-11; stationary ones NEC 690/706.
