I seem to remember this happening before.
To many small producers dumping into the grid, and the utility will not like it.
It happened in NV.
The electric utility has to pay the individual homeowner solar electric producer based on the NET METERING agreement with the state. This agreement can be changed by the state Public Utilities Commission. The utility got the three person PUC of NV to change the Net Metering rate they had to pay.
The people of NV that had installed residential solar arrays based on their payback from the net metering flipped out. They organized and protested at the capital/governors. The PUC changed it back.
The point is that utilities are in the business to make money. If too many people add rooftop solar, the utility will eventually get the government to change the net metering rate they pay.
FYI, I considered building an array at my residence in NH.
The NH net metering rate is locked in through 2040. This is something anyone buying an array should check.
