Hiring a solar company in Yuba City
Solar companies in Yuba City run an eligible rooftop design through SolarAPP+, then apply for the building permit in the City's online portal, where the City invoices its fees and issues the permit once they are paid. Inspectors do not need you home for an exterior-only inspection. PG&E serves the city, with no community choice provider. Compare at least three written bids built on your own PG&E bill.
Start with your Yuba City electricity bill
Yuba City is PG&E territory with no community choice provider on the California Energy Commission's maps, so PG&E supplies generation and delivery and its Solar Billing Plan values your exports. The plan bills monthly with an annual True-Up statement, and customers who start before 2028 receive Energy Export Bonus Credits set when the system gets permission to operate. Each bidder should model that plan from your own usage.
Yuba City's SolarAPP+ permit, step by step
The City uses SolarAPP+ for the majority of residential, roof-mounted retrofit systems, and only projects that match the SolarAPP+ eligibility list can use it. First the contractor submits the design through SolarAPP+ and pays its processing fee. Then it creates a building permit application in the City's online portal; the City reviews the application, invoices the building permit fees and issues the permit after they are paid. Permits can also be submitted and paid for at City Hall.
The City's reports to the Energy Commission show how common the online route has become: 920 residential solar permits in 2023, about 85% issued online and about 20% with battery storage. Sutter County is exempt from SB 379's automated permitting requirement, so a home outside the city limits may follow a different process.
Inspection day in Yuba City
Inspections are requested online or by phone at (530) 822-4901 by 5 p.m. the business day before, in a morning or afternoon slot; on the day, a two-hour window can be requested at (530) 799-0549. You will need the Yuba City permit number, the inspection type and a contact name and phone number. The City does not give a time or advance notice for inspections that only need exterior yard access.
By 8 a.m. the homeowner or installer should have pets secured, the signed Permission for Inspection Access form and signed smoke and carbon monoxide alarm form, the permit and the approved plans left on the front porch or near the main electrical panel, unlocked access that does not go through the house or garage, and a ladder if needed. The inspector does not need to reach panels on a sloped roof that are visible from the ground. Results post to the City's website the next business day.
What a Yuba City quote needs to explain
| Check | Ask each bidder |
|---|---|
| SolarAPP+ fit | Confirm the design is on the eligibility list; panel upgrades and breaker derates are not. |
| Inspection prep | List the forms and plans that must be left out by 8 a.m. on inspection day. |
| Inverter location | Say whether the inverter is in the garage, so interior access can be arranged. |
| PG&E plan | Model PG&E's Solar Billing Plan, including bonus credits for a pre-2028 start. |

Use these guides to prepare the specific questions a written bid needs to answer.
A comparison to ask for
Ask each bidder whether its design fits Yuba City's SolarAPP+ list; a panel upgrade or breaker derate takes the job out of it. Then ask what the inspection day will need from you: the City wants signed access and smoke-alarm forms, the permit and plans left out by 8 a.m., and unlocked access that does not go through the house.

What are the best solar companies in Yuba City?
This site does not rank them. Shortlist companies with a CSLB license covering solar that are registered with SolarAPP+ and confirm your address in writing, then compare at least three written bids for the same system, each built on your own PG&E bill.
Do I need to be home for a Yuba City solar inspection?
Usually not. The City says it gives no inspection time or advance notice for inspections that only need exterior access, and you need not be present unless the inverter is inside the garage or another locked area. By 8 a.m. you must secure pets, leave the signed access and smoke and carbon monoxide alarm forms, the permit and the approved plans on the porch or by the main panel, and provide unlocked access that does not go through the house.
How do I schedule a solar inspection in Yuba City?
Online or by calling the inspection request line at (530) 822-4901 by 5 p.m. the business day before. Morning (8 a.m. to noon) or afternoon (noon to 3 p.m.) slots are available, and two-hour windows can be requested on the day by calling (530) 799-0549.
