Hiring a solar company in La Habra

Solar companies in La Habra can permit a system of 10 kW or less through the City's streamlined toolkit, with a combined building and electrical permit reviewed in about three working days and fees capped at $500 on the standard plan, or use SolarAPP+. Taking panels off for a reroof needs its own removal and reinstall permit. SCE supplies the power, with no community choice provider. Compare at least three written bids.

Start with your La Habra electricity bill

La Habra is SCE territory, and the Energy Commission's community choice map shows no provider over almost all of the city, so SCE bills both generation and delivery. SCE's Solar Billing Plan values exports by the hour and season, locks new customers' export values for nine years, and adds a credit of about $0.04 per kWh for eligible customers who enroll before 2028. Each bidder should model it from your own bill.

La Habra's 10 kW toolkit permit

La Habra follows the state's solar permitting guidebook for small systems. Its Toolkit Document #1 covers photovoltaic installations of 10 kW or less, which need only a combination building and electrical permit; Planning and Fire Department approvals are not required at that size. The application goes in through the City's online permit portal with the eligibility checklist and a standard plan, and the City says applications should be reviewed within three working days. The permit itself is issued at the Building and Safety office.

On the standard plan, total fees will not exceed $500. Plan check is billed at an hourly rate with a one-hour minimum, permit fees follow the construction valuation in the City's fee table, and Strong Motion and CBSC fees apply. An electrical panel upgrade needs its own permit application, and a third plan review adds another plan check fee. Larger or battery systems can take SolarAPP+, which the City reported to the Energy Commission as its automated platform.

Removing and reinstalling panels in La Habra

When a roof under an existing system needs work, La Habra treats the removal and reinstallation as its own permit. The contractor must hold a B, C-10 or C-46 license, and the application and site plan list that contractor, a detailed scope of work, the size and location of the existing system and where the panels will be stored. The permit is not a way to enlarge or change the system; the City asks that the plans say so.

Ownership matters too. If the system is leased or financed and the contractor doing the work is not the leasing company, the applicant must include the system owner's letter accepting the removal and reinstallation. Plans go in electronically through the City's portal. If your roof is near the end of its life, it may be cheaper to reroof before the panels go up.

What a La Habra quote needs to explain

A comparison to ask for

If your roof will need replacing, ask each bidder how it would handle removing and reinstalling the panels later. La Habra requires a separate permit for that work, done by a B, C-10 or C-46 licensed contractor, and if the system is leased, the owner's written acceptance. A bid that includes a reroof now avoids that step.
