"Researchers argue that home solar panels are raising the price of electricity and reducing the need for cheaper large solar farms — making the entire transition to clean energy more expensive...."

"Researchers say that... many states and utilities provide very lucrative deals for users of rooftop solar — often compensating owners of home panels more than the value of their solar to the grid. In states like California and Arizona... in the middle of the day homeowners might get 20 cents back for each kilowatt-hour they send to the grid. But for a grid already flooded with solar, the value of that extra energy is close to zero. The result is that richer homeowners who can afford solar get cheap electricity bills — while poorer residents see higher bills to compensate. In California alone, researchers at UC Berkeley and the California Public Advocates Office estimated that rooftop solar will add between $4 billion and $6.5 billion to customers’ bills in 2024...."
