My husband and I literally had this conversation today. He's found a guy to talk to, hopefully tomorrow.Yes, sort of. Basically my excess power gets sent to the grid where they keep an accounting of how much power I'm sending them. If it's a cloudy day and I need power from the grid, it pulls from that tally first before I get charged. Essentially that offset needs to be depleted before I am charged for power like my conventional system. However I also have a propane powered generator backup for cases where the panels can't make enough AND the grid is down.
As silly as it may sound, my biggest concern is keeping the freezers working so stockpiled food isn't wasted by rolling blackouts. Second to that is the ability to reduce dependency on the grid.
I will be getting battery backups but not until the next generation batteries are available. They are cheaper, more efficient, and are expected to last 3x as long.
