Thanks for the question, Kaushik! The trick is that this proposed system would work in tandem with net metering.

During the day, the 16.5 KW of "extra" panels would supply enough power to run the Antminer, plus a lot more beyond that. While they were generating extra power, my meter would spin backwards.

At night, though, the panels would stop generating, but the Antminer would keep mining and using power. My meter would spin forwards. The goal would be for the power supplied by my "extra" panels to offset the total daily power usage of the Antminer.

If not for net metering, I'd need to install a big battery bank to capture the excess power from the panels during the day, and use it to keep the Antminer running at night. With net metering, I can just spin the meter backwards during the day to offset the Antminer's nighttime usage.

So this system would work in tandem with--and hopefully strengthen--net metering. It would actually be a benefit to the grid's stability, since it would generate excess power during the day when usage is higher across the grid, and then consume power at night when grid demand is lower.

The biggest thing is that this avoids the net metering situation where a user generates too much power, and then sells it back to the grid at an economic loss. Instead of having that loss, they would make a big potential gain, because that excess power would be used for mining crypto.
