Thank you Scotty for the description of the current "no net metering" option in Hawaii. I understand that this kind of self-supply arrangements is also common in other countries. The next version of SAM (due for release in early 2016) will have no net metering options where excess generation (calculated either on an hourly or monthly basis) is sold at a different rate than the buy rate.
Also, you may be interested in the new version of NREL's National Solar Radiation Database (NSRDB) at
nsrdb.nrel.gov
where you can download solar resource and weather data in the SAM CSV format for any location in the U.S., including Hawaii at a 4 square kilometer resolution.
Best regards,
Paul.
