California Public Utilities Commission voted to approve the new Net Energy Metering 3.0 program earlier this year which took effect in April 2023. The new program referred to as the Solar Billing Program incentives homeowners to go solar with a battery storage solution to reduce their monthly electrical utility expenses.
If you're someone in Southern California Edison or San Diego Gas and Electric territory, you need to understand that a solar only system will not save you anywhere near as much per month in utility expenses as a solar battery system will.
