This does not earn me money but it does earn me kWh credits, which means that if I am net negative for energy import in the summer and net positive for import in the winter, I can be net zero (or close to it) for the year.
In MA and a few other states, polluters are also required to buy “renewable energy credits.” Since I have a solar array I can sell my RECs whether I export energy or not. It’s my first year with a solar array, so I’m not sure how much to expect, but neighbors tell me that they earn between $500-$1000 a year.
In a future with solar and batteries, daytime and nighttime electricity pricing cannot be equal - else nobody would bother to have a battery (grid scale or at home).
Rules and regulations could solve that problem (meter not allowed to go backwards, solar companies are forced to pay some kind of battery credit, etc), but the free market will always outcompete.
Therefore, I forsee the future lies in 'smart' electricity meters which can charge different rates at different times of day - perhaps with minute by minute live pricing.
