Net metering is a temporary state intended to build critical mass and get mass production going. Solar panel owners don't pay the full cost of grid services, and utilities are not paying them for the full value of the electricity fed back in.

Residential solar IMO is mal-investment because grid scale solar has better economies of scale. Solar plants are easier to maintain. The grid is not built for widespread net metering. Rooftop solar has more fatalities than nuclear because of installers falling off.
