Availability is calculated only within the time window from 2 hours after sunrise to 2 hours before sunset. Outside of this time window, availability is considered “Not evaluated.” Periods labeled “Not evaluated” do not factor into the daily availability at site or inverter level.

Please note that only inverters are included in the availability calculation. The availability of other device types such as DC strings or MPP trackers does not play a role in the calculation of inverter availability.
