Hiring a solar company in Vallejo
Solar companies in Vallejo can get an instant permit for residential solar or battery storage through the Symbium portal on the City's permit page, with eTRAKiT as the City's online permit system. PG&E delivers the power to almost all of the city and MCE supplies the generation; a small area is mapped to another utility. Compare at least three written bids built on your own bill.
Vallejo's Symbium instant permit
Vallejo is one of the Bay Area cities that met SB 379 with Symbium rather than SolarAPP+. Its Building Division says contractors and homeowners seeking residential solar or energy storage permits under SB 379 can apply for instantaneous permit issuance through the Symbium portal linked from the City's page. Other building permits are filed in eTRAKiT, the City's online permitting system; a new user has to register before applying.
The numbers suggest most Vallejo jobs still take the regular route. Of 1,022 residential solar permits the City reported to the Energy Commission for 2024, 86 were issued online. That can be because a design falls outside the automated checks or because the installer chose to file conventionally. Either way, it is fair to ask each bidder which route it will use for your roof and what that means for the schedule.
What a Vallejo quote needs to explain
| Check | Ask each bidder |
|---|---|
| Utility on the bill | Name PG&E and MCE, or the other utility if your bill shows one, and model that utility's rules. |
| Permit route | Say whether the design qualifies for the Symbium instant permit or goes through eTRAKiT review. |
| MCE credits | Show MCE generation credits and PG&E delivery charges separately, for your application date. |
| Battery | Price the battery as its own line, with usable kWh and backed-up circuits. |

Use these guides to prepare the specific questions a written bid needs to answer.
A comparison to ask for
Only about 8% of Vallejo's 2024 solar permits were issued online, so the instant route is not yet the norm. Ask each bidder whether your design qualifies for Symbium's instant permit and, if not, how long its recent Vallejo permits took in regular review. Then compare the MCE and PG&E bill each proposal leaves you with.
Verify the company behind the Vallejo quote
Match the business name and license number on each Vallejo proposal to the CSLB record, then use our contractor verification steps, the quote comparison guide and the PPA, loan, lease and cash comparison. What you pay the utility today is on the Vallejo rates and bills page.
