We are working on an ASHRAE 90.1 model in Nevada and are adding the solar information manually to the LEED online forms, post energy modeling (so our solar energy is not appearing on the software generated report). We are aware that this will require additional documentation to be provided to the LEED reviewer. However, we need clarification on what would be an acceptable method of calculation for the annual output? And what documentation must be provided?
Also, would a CF1R PV calculation be an acceptable annual output for the state of California?

Either way works fine for LEED.
The most commonly used calculation method we see is PV Watts. It is helpful to provide the inputs and calculations used to determine the PV system output.
I am not sure what the State of California accepts but I think LEED would likely accept the result of the calculator that generates the form you reference. Showing the calculation inputs as well as the outputs is helpful.
