Not saying this guy is right or wrong but I will say again that it has to be great to not need the electric company. It also has to be great to not have to pay taxes on the electricity from the electric company.
How many of you have “smart” meters. This guy doesn’t need to worry about(at least at the level us who buy electricity from an electric company) the government regulating his electricity use, through the end game of “smart” meters that have the ability to transmit data on your electricity usage, what you use when, when you are home, when you are probably awake or sleeping, etc.
Eventually, “smart” meters will probably be used to cut your power down or off when someone deems it necessary.
This guy probably wont have to worry about those things as much as us.
Most “grid tie” PV systems do not have anyway to store energy when the power goes off. Meaning no batteries. The grid and the inverter are synchronised to each other. If the grid goes out, most of these folks who use smart meters are dead in the water also. The utilities don’t want you to export power to their dead power lines.
I know there are many that have batteries as back up for such events, but they are not usually hooked into the grid tie.
If I were to add batteries to my grid tie PV system, I would be forced to disconnect my system.
