Difference in open-circuit voltage23.2 V

The voltage difference repeats for each panel in series. Check the cold-temperature value too.

Difference in working current1.4 A

This matters for parallel wiring and inputs with low current limits.

*The −10°C value is a calculation example using the temperature coefficient, not a forecast for your location. Check the actual minimum temperature, label, manual, polarity, cables and protection requirements.
