Hiring a solar company in Bellflower

Solar companies in Bellflower face roof rules that took effect January 1, 2026: a C-39 roofing contractor must certify the roof before and after the install, with a one-year leak warranty, and the owner must authorize the permit in writing. Plans are reviewed through the City's Willdan Geocivix portal, and fees are paid in person. SCE supplies and delivers the power. Compare at least three written bids built on your own SCE bill.

Start with your Bellflower electricity bill

Bellflower is Southern California Edison territory for both generation and delivery: the California Energy Commission's map shows no community choice provider over the city. A new system goes on SCE's Solar Billing Plan, so each proposal should use SCE's hourly export credits and your own twelve months of SCE usage.

Bellflower's 2026 roof and permit requirements

The City's minimum additional requirements for solar PV permits took effect on January 1, 2026. Before the permit is issued, the property owner must authorize it in writing, and the plans must describe the existing roof framing, with member types, sizes, spans and spacing, and verify that the roof will carry the new system, adding framing plans for any strengthening. At plan check, a C-39 roofing contractor must confirm in writing that the roof covering shows no deterioration and is in good condition; that step is waived if a complete re-roof permit was issued and finaled within the past five years.

Before the final building inspection, a C-39 roofing contractor must confirm in writing that the whole roof is in acceptable condition after the installation and was not compromised, with at least a one-year warranty against leaks or product replacement. Any electrical work beyond the direct connection into the existing panel must be done by a licensed individual or electrical contractor, and any related gas or water plumbing by licensed plumbers. The Building Official can waive requirements only for cause.

Filing, fees and inspections

The process starts by email: the applicant sends the solar application to the City's permit technicians and receives a plan check number. Plans are then uploaded to the Willdan Geocivix portal as multi-page PDFs by discipline, with calculations and specifications as separate files, and review comments come back by email for resubmittal through the same portal. Plan check and permit fees are paid after approval, in person at City Hall, at an appointment with the Building Counter, where the approved sets are stamped and the permit and job card are issued.

Inspections are requested by phone once the permit is issued, by 3 p.m. for a next-business-day attempt. On the utility side, a new system goes on SCE's Solar Billing Plan: export credits vary by hour and season, SCE locks their values for nine years from the year you start, and customers who enroll before 2028 get a bonus credit of about $0.04 per kWh, or about $0.09 if income-qualified.

What a Bellflower quote needs to explain

A comparison to ask for

Because Bellflower requires a roofing contractor's sign-off before and after the install, ask every bidder who provides it: its own C-39 license, a roofing partner, or you. A bid that leaves the roof certification out, or that assumes a recent re-roof you do not have, is not comparable with one that includes it.
