Ratings and limits
| STC (1000 W/m², 25 °C) | Pmax 100 W · Voc 22.4 V · Isc 5.75 A · Vmp 18.2 V · Imp 5.5 A · 36 cells in series, 3 bypass diodes |
|---|---|
| Temperature coefficients | Voc -0.3 %/°C · Pmax -0.4 %/°C · Isc +0.05 %/°C |
| NOCT | 45 °C: cells run about 31 °C over ambient in full sun |
| Voc at 10 °C ambient, dawn | 23.4 V: what the string must be sized for |
| Vmp at 35 °C noon (cells ${35+Math.round((d.noct-20)/800*900)} °C) | 15.4 V |
How to use it
Feeds a charge controller, never a battery directly. Peak sun hours in Cebu are about 4–5 per day.
