How is the availability of my PV site calculated?

This article describes the calculation of availability at inverter and site level

Term/Status Description

Availability

The daily availability of the site is calculated from the average availability of all inverters in the site.

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.

100% When the average hourly inverter yield is above 5Wh.
