Hiring a solar company in Fallbrook
Fallbrook is unincorporated, so solar companies here pull the permit from the County of San Diego's Planning & Development Services, not a city, and the County reported no automated SB 379 platform to the Energy Commission. SDG&E delivers the power and San Diego Community Power, which serves unincorporated San Diego County, supplies the generation on the Commission's map. Compare at least three written bids built on your own bill.
Permits for an unincorporated Fallbrook home
Fallbrook is a community of unincorporated San Diego County, so there is no city building department. The County of San Diego's Planning & Development Services issues building permits here, and its building forms page lists the solar documents it works from: online roof-mount solar PV submittal guidance, minimum plan requirements for solar photovoltaic projects, a residential roof-mount solar PV building code plan check, and the residential building permit application.
The County told the Energy Commission it has no automated SB 379 solar permitting platform, and it has not filed an annual permit report in the Commission's data file. That means a Fallbrook project is reviewed by County staff rather than approved instantly. Ask each bidder how many unincorporated San Diego County permits it has pulled recently and how long they took.
What a Fallbrook quote needs to explain
| Check | Ask each bidder |
|---|---|
| County permit | Say how the job will be submitted to San Diego County PDS and the expected plan review time. |
| Generation | Name SDCP or SDG&E from your bill and model that provider's solar credits. |
| Rate plan | Model SDG&E's EV-TOU-5 with on-peak from 4 to 9 p.m. |
| System size | Size to past use; SDG&E allows up to 50% more only with an attestation of higher use. |

A comparison to ask for
Put the same roof planes, shading and twelve months of usage into every Fallbrook bid, and ask each bidder how long its recent PDS solar permits took. Then compare the SDG&E delivery charges and SDCP generation charges each proposal leaves you with under EV-TOU-5, where on-peak runs from 4 to 9 p.m.

Fallbrook solar quote questions
What are the best solar companies in Fallbrook?
This site does not rank them. Shortlist companies with a CSLB license covering solar that have pulled San Diego County permits for unincorporated homes and confirm your address in writing, then compare at least three written bids for the same system.
Who issues solar permits in Fallbrook?
The County of San Diego's Planning & Development Services, because Fallbrook is unincorporated. The County reported no automated SB 379 solar permitting platform to the Energy Commission, so plan on a PDS plan review.
Is Fallbrook served by San Diego Community Power?
On the Energy Commission's community choice map, yes: SDCP covers all of Fallbrook, and SDCP says it serves the unincorporated areas of San Diego County. SDG&E still delivers the power and sends the bill. Check the generation provider printed on your own bill.
What does SDCP pay for surplus solar?
For net energy metering customers, San Diego Community Power pays the Net Surplus Compensation rate plus a $0.0075 per kWh bonus, and issues a check automatically when the amount exceeds $100 per account.
