The California Supreme Court has made significant rulings regarding rooftop solar panel policies, handing victories to solar owners and environmental groups. The court ordered a re-evaluation of the state’s rooftop solar credit policies, rejecting the previously used deferential review standard for decisions made by the California Public Utilities Commission (CPUC). This ruling leads to uncertainty in California’s rooftop solar regulations as the court kicks the decision on solar rates back to a lower court for further consideration. Additionally, a lawsuit concerning the NEM 3.0 solar decision is set to be heard, indicating ongoing disputes over solar compensation and fairness for customers.
