The kilowatt-hour per kilowatt-year metric is the annual electric output in year one EOutputYear1 divided by the system capacity PSystemCapacity. For photovoltaic systems, the system capacity is the Array Power on the Array page. For concentrating solar power systems, the system capacity is the Rated Turbine Net Capacity on the Power Block page.

Where,
EOutputYear1 (AC kWh/year) |
The total annual electric generation in the first year of operation reported on the Metrics table, and in the year one column of the project cash flow. |
PSystemCapacity (DC kW) |
The system's rated capacity expressed in kilowatts (see table below). |
The system capacity depends on technology being modeled. Note that Solar Advisor converts the capacity value to kW before using it in the calculation.
