California Solar Reform Threatens US Home Solar Installers.

California's upcoming policy change to reduce the subsidy for rooftop solar owners sending excess power into the grid is expected to slow down the US residential solar market. The reform will reduce the money credited to rooftop solar owners, which has underpinned more than a decade of explosive growth. Solar companies say the move threatens California's efforts to decarbonize the grid by 2045 by slowing installations, while state regulators say the reform will shore up power reliability by adding new incentives for homeowners to buy batteries that store clean power on site.
