Frequently Asked Questions About Solar Battery Storage

What is NEM 3.0 and how does solar battery storage factor into play?

NEM 3.0 (Net Energy Metering 3.0) is California's current solar billing policy. Unlike NEM 2.0, it significantly reduces the export credits you earn for sending excess solar back to the grid — making it less valuable to export power and more valuable to store it. A battery lets you use your solar when rates are highest rather than selling it back at lower NEM 3.0 rates, which is why pairing storage with solar has become essential for maximizing your savings under the new rules.
