When you have net metering, how does SDG&E determines that your system is over producing ? Because, you could be over producing one month & then under producing another month.[/quote]From month to month, it averages out. But I think at the end of the year, if you have a surplus, they’ll pay you out. Don’t quote me on this, since my system doesn’t over produce. On months where I over produce, it keep on adding up until months where I under produce and the the kWh will be used.
