NEM 3.0 Net Billing Guide (Battery Storage Arbitrage)
California NEM 3.0 changed solar economics. Here is how pairing panels with home battery storage preserves a 7-to-9 year payback horizon under peak rate arbitrage.
1. Understanding NEM 3.0 Avoided Cost Calculator Rates
Enacted by the California Public Utilities Commission (CPUC), NEM 3.0 shifted solar from traditional 1:1 net metering to instantaneous net billing based on avoided cost.
