PG&E Solar & Battery Savings Calculator (NEM 3.0)
Calculate true payback periods using PG&E avoided cost rates—not generic NEM 2.0 based estimates.
Updated December 2025: Now using 2026 avoided cost, E-ELEC, and E-TOU-D rates.
Privacy First: Your address is sent to Google Maps Solar API only to request your solar profile. All other calculations remain client side (in your browser), and I do not receive or collect any of it.
Other solar calculators base their calculations on NEM 2.0 and are outdated, yielding less accurate predictions.
This NEM 3.0 calculator gives a better estimate by accounting for the complexities of:
- 576 Avoided Cost Rates: Precise export values for every hour, day, and month of the year.
- Battery Arbitrage: Storing solar to sell during evening peaks.
- Real-World Efficiency: Accounting for round-trip battery losses.
- Hourly Variance: Seasonal generation & consumption profiles.
