Assumptions: PG&E NEM 3.0 net billing tariff (exports credited at avoided-cost rate, grid imports billed at retail). Self-consumption % estimated from battery capacity relative to daily production. Bay Area install cost of $3.75/W and Powerwall-class battery pricing. 30% federal ITC applied to panels + battery. Annual production derated for panel degradation and roof orientation. Actual savings vary with shading, weather, rate plan changes, and PG&E tariff schedules.
