Solar in Santa Rosa: build for use, not for a credit

Resilience is the point. Oversizing is not.

Santa Rosa created a Resilient City combining district after the October 2017 fires, covering fire-impacted areas including Coffey Park and the Highway 101 Corridor and Roundbarn area. The rebuild context is real, and it is reasonable for a household to put outage capability on the table. Read the City's urgency ordinance.

But a resilience goal has to be named. Is it refrigeration and internet for a night, a medical load, a well pump, or a whole house through an extended event? Those are different designs with different storage requirements. Panels alone do not provide backup during an outage without equipment designed for it.

Santa Rosa has 68,234 occupied homes in the ACS data, with 26.3 percent using electricity as the main heating fuel. That is enough electric load to make self-consumption analysis matter, especially for households adding heat pumps or EV charging. The Census heating table gives the citywide shape, not a substitute for your own interval data.

The City has an instant route, with a clear price tag

Licensed contractors can use Santa Rosa's SolarAPP+ and Accela Citizen Access process for eligible residential rooftop PV, including systems with storage. The City calls it instantaneous permitting for eligible projects. That is useful, but it is an eligibility statement, not a guarantee that every roof, electrical upgrade or field correction stays simple. The City's solar installation page has the current process.

The adopted fee schedule lists $100.18 for residential roof-mount photovoltaic plan check and $300.56 for inspection, a combined $400.74. Santa Rosa revises its fee schedule each January 1 and July 1, so confirm the active figure before contract signing. Check the fee schedule.

For a standard PV job without storage, the City publishes a three-day first and subsequent review target. With energy storage, it publishes 14 days. SolarAPP+ can be faster where the system qualifies, but neither number is a promise for utility permission to operate or contractor scheduling.

The Sonoma Clean Power detail most proposals will blur

SCP's 2026 Solar Billing Plan net surplus compensation rate is 3.079 cents per kWh. That is the relevant disclosed rate for new Solar Billing Plan customers. Do not let anyone replace it with the legacy NetGreen story. SCP's current rate sheet puts the new-program rate in black and white.

Legacy NetGreen customers are different. SCP says their net surplus compensation equals PG&E's 12-month average plus 1 cent per kWh, and its legacy materials say they receive the full retail CleanStart generation rate for energy generated. That premium applies to legacy NetGreen customers, not a new Solar Billing Plan account. The NetGreen technical guide is explicit.

SCP conducts an annual spring cash-out. Balances of $200 or more are paid by check, smaller balances become bill credit, and the annual cap is $5,000. Those are settlement rules, not an argument for designing a system around surplus. Read SCP's tariff.

The federal homeowner 25D credit ended for expenditures after December 31, 2025, including installations completed in 2026. Treat any sales presentation that still uses it in the cash price as a problem to resolve before moving forward. CRS explains the timing rule.

Run the screening math, then try to break it

This calculator is deliberately less detailed than the actual billing stack. It is useful for comparing size and production sensitivity. It cannot price SCP and PG&E credits by interval or tell you what a particular roof will self-consume.
