Hello,
As we discuss in the webinar, in SAM 2014.1.14, we changed the net metering model to correctly calculate monthly credits. In earlier versions of SAM, net metering was calculated on an hourly basis, which modeled a project where 100% of the renewable energy system's electrical output was effectively purchased by the utility.
Best regards,
Paul.
