Yeah in the US it's all net metering. The power company gets to make money off your infrastructure lol. Pretty gay if you ask me. I plan to setup solar on my 40x60 grow building but all the power generated will be used in real time so no need to worry about getting screwed. Now later down the road when I am retired and no longer growing, long after the solar has paid for itself, even with cell output degraded to say 50% I will still make a LOT more power than I would use in my home so I would get that net metering check to help pay for other bills
