Verified California facts
Utilities and residential rates
Utilities: Pacific Gas and Electric Company, Southern California Edison, San Diego Gas & Electric.
The three investor-owned utilities to which the CPUC Net Billing Tariff claim below is expressly scoped; each utility name is independently linked to its own site.
Not established from an approved source. No defensible comparable range was derived: current residential tariffs vary materially by utility, baseline zone, usage tier, time-of-use period, and plan.
Export compensation
Net Billing Tariff (NBT) — net-billing tariff.
Audience: Residential owner-occupied systems.
Covered utilities: Pacific Gas and Electric Company, Southern California Edison, San Diego Gas & Electric.
Successor to NEM 2.0 for customers submitting an interconnection application on or after April 15, 2023. It is not full-retail net metering and is not presented as a rule for California's locally governed public utilities.
Permitting and state programs
Not established from an approved source. No approved primary source established one statewide permit-cost range and timeline applicable across local jurisdictions.
Not established from an approved source. CARE was removed because it is general bill assistance, not a solar installation program. No actual residential solar program was added without a sufficiently reviewed primary program source.
State tax treatment
Sales tax
Not established from an approved source. No blanket state-level residential solar sales-tax exemption was established from an approved source.
Property tax
Active Solar Energy System New Construction Exclusion: New-construction assessment exclusion through the 2025–26 fiscal year. A qualifying active solar system is not assessed as new construction; the Board of Equalization states this is an exclusion, not an exemption, and notes a January 1, 2027 sunset.

Treatment type: assessment exclusion—not an exemption.
Scheduled to sunset January 1, 2027. California Board of Equalization sunset notice (opens in a new tab)
Applicability review
Only findings tagged residential-owner-occupied may render as values. Related provisions rejected for audience mismatch remain visible here for audit.
Rejected for programs: California Alternate Rates for Energy (CARE)
appliesTo: other. Rejected because CARE is income-qualified utility bill assistance, not a residential solar installation incentive. A residential solar equivalent was searched for but not stored without a sufficiently reviewed primary program source.
