What a reset involves, and the CSLB classes to ask for
A removal and reinstall takes your array off the roof so the roof can be worked on, then puts the same panels back and reconnects them. CSLB's Solar Smart page names A (General Engineering), B (General Building), C-10 Electrical and C-46 Solar as the classes that can legally install photovoltaic systems, and its C-46 description covers work to install, modify, maintain and repair them. C-4, C-36 and C-53 are solar heating classes and aren't on that list.
Two companies may handle your array on a reset: the roofer, and whoever unplugs and reconnects the panels. Ask each one for its CSLB number and class and check both on CSLB's license lookup. CSLB's supporting-information form for solar contracts asks whether subcontractors will be used, and that's the question to put to whoever quotes the reset, with the answer in writing.
What removing and reinstalling panels costs in California
Our model puts removal and reinstall at $220 to $435 per panel, removed and put back for roof work. It adjusts two national ranges by California's installer wage ratio of 1.09, and no permit fee is added to the per-panel figure. It's a model, not a quote, and there's no federal credit to take off for 2026 work.
The range doesn't cover roof work, new racking or flashing, a damaged panel, or an inverter that fails when it's switched back on. Ask whether the price is per panel or per job, whether storing the panels is included, and whether the company retests the system afterward.
| Item | Figure | What it is |
|---|---|---|
| Estimated range, not a quote | $220 to $435 per panel, removed and put back for roof work | Built from 2 national published ranges, adjusted by the California solar installer wage ratio (1.09). Before any incentive: there is no federal credit for a system installed in 2026. Basis: no California company price for this job, so the national estimate stands. |
| Solar photovoltaic installer wage, California mean | $30.42 an hour | Pay for installers per BLS OEWS (May 2025); the price you are quoted is set separately. |
| Down payment limit on a home improvement contract | $1,000 or 10 percent, whichever is less | B&P 7159.5, as CSLB applies it to residential solar installation: a cap on the deposit, not a price for the work. |
Estimated range. Built from national published ranges (2 sources), adjusted by California's solar installer wage ratio to the US (1.09, BLS May 2025), plus the city solar permit fee where the city publishes one. Not a quote. One California installer publishes its own quoted range (per watt and per battery), too few to build a range from; the others print blog averages, which we do not count. We have no California company price for this job, so the range is our national estimate alone. Full method. Prices as of Oct 23, 2026.
One roof, two contracts: the dates and payments to pin down
Expect a roof contract and a solar contract. Settle in writing who is responsible for the panels while they're off the roof, where they're stored, and who tests the system once it's back. CSLB bulletin 20-22 treats a residential solar installation as home improvement, so that contract needs an approximate start date and completion date, with prices and progress payments in dollars and cents. Apart from a down payment of no more than $1,000 or 10 percent of the price, whichever is less (B&P 7159.5), no payment may run ahead of the work performed or materials delivered.
Those rules are written for an installation. Ask for the same dates and payment terms on a reset quote. Solar Smart's payment advice fits too: keep control of what you pay the contractor, don't let a lender pay ahead of the work, and get mechanics lien releases signed.
Panels you lease or buy power from
With a lease or a power purchase agreement, you don't own the system. CSLB's supporting-information form asks whether the deal is a lease or PPA and whether the contract can transfer to a new homeowner. If the company owns your panels, ask it, not the roofer, who may detach them and on what terms, and get that answer before anyone sets a roof date.
When a reset is worth pricing, and the layout when panels go back
A roof that will need replacing during the system's life is the reason to price the reset together with the roof job, so one schedule covers both. If no roofer or inspector has told you the roof needs work, there's nothing to take down yet.
If the panels go back in a different layout, ask the building department whether the reset is checked against R324.6 of the 2022 California Residential Code. That edition asks for two pathways at least 36 inches wide on separate roof planes and an 18-inch ridge setback when the array covers 33 percent or less of the roof. The 2025 code took effect January 1, 2026 and may differ.
Added panels bring the utility in. SCE's FAQ says added panels need a new Interconnection Application and receive a new permission to operate, and it recommends not running the added equipment before then. PG&E's Solar Billing Plan page says legacy NEM and NEM2 customers aren't affected unless they "modify or expand" the system above the thresholds it prints: 10 percent of the original nameplate capacity, or more than 1 kW. In Rule 21 terms the test is a Material Modification, which SCE's tariff sheet defines by "a material impact on cost or timing" of other queued requests or a change in the point of interconnection. SCE's FAQ doesn't say whether the same panels going back in the same layout need anything from SCE, so ask the company to check with SCE before the roof date.
Find your permission-to-operate letter before the roof date. Customers on NEM 2.0 may stay on it for 20 years from the date they interconnected, and NBT customers keep their tariff for nine years, so ask the company in writing whether reconnecting the array involves the utility. A battery wired to the array has its own permit rows on the battery page, and the solar installation page covers the contract rules for new work.
What Roseville and San Diego ask for when panels come off for a new roof
Roseville makes the reset its own permit. Its Building Division acknowledgement form, created in 2018, is required with any roofing permit that includes taking the PV system off. The form says "a separate permit will be required to re-install the PV system" and that it "shall be re-installed in accordance with the original City approved drawings." Find those drawings before the roofer starts.
San Diego's Information Bulletin 301 wants the paper trail. When roof-mounted PV comes off for a new roof covering, "An original approved record plan set must accompany the submitted PV plans," and the city may require an inspection of the existing system before it's removed. The reinstall permit "does not allow any alteration of the original equipment or system," and the work goes to a contractor holding a C-10 or C-46 license.
The 2022 California Residential Code sends rooftop panels to R324 and the California Electrical Code (R907.1) and to the manufacturer's instructions (R907.3). Panels on top of a roof "shall be listed and labeled in accordance with UL 2703" (R907.4). Its reroofing section, R908.1, sends a new or recovered roof covering to Chapter 9. Those are 2022 sections. The 2025 edition took effect January 1, 2026 and may differ, so ask the building department which one your reset is checked against.
When panel trouble can't wait
- Fire or smoke at the inverter, panels or wiring, or a burning smell near them: call 911 and stay away from the equipment.
- A cracked panel with no smoke, no burning smell and no heat.
- The monitoring app shows lower production or has gone offline after roof work.
What to settle before the roof date
- Write down the make and model of the panels and inverter from your contract or the equipment labels you can read from the ground.
- Find the contract, warranty papers and permission-to-operate letter.
- Take a photo of the monitoring app's current output so you can compare it after the panels are back.
Permit and utility questions for a reset
Riverside's fee schedule, created June 18, 2025, prints $350 for a residential solar energy system up to 15 kW. That line names a whole system, so ask your building department whether reconnecting the array after roof work needs an electrical permit before you set the roof date.
Ask the company, too, whether it will contact PG&E, SCE or SDG&E when the system comes back on. LADWP and SMUD are municipal utilities with their own rules, so customers there ask the utility directly.
Ask for the company's contractor license number and look it up with your state's licensing board before you sign.
Questions people ask
Who can remove and reinstall solar panels in California?
Ask for a CSLB number in one of the classes CSLB names for PV: A, B, C-10 or C-46. C-4, C-36 and C-53 are solar heating classes, and they aren't on that list.
Does a reinstall need a permit?
Ask your building department before the roof date. Roseville requires a separate permit to reinstall the array after a re-roof, and San Diego's reinstall permit doesn't allow changes to the original equipment or system.
Does the three-day cancellation right cover a reset?
CSLB applies it to a residential solar installation, so ask whether your reset contract carries the notice. The B&P 7159 notice gives a buyer three business days, or five for a buyer 65 or older on a contract entered since January 1, 2021, and anything paid comes back within 10 days.
What if my panels are leased?
Then the company owns the system, and the contract decides who may detach it. CSLB's supporting-information form asks whether the deal is a lease or PPA and whether it can transfer to a new homeowner.
How much does removal and reinstall cost in California?
Our model puts it at $220 to $435 per panel, removed and put back for roof work, an estimate and not a quote. It covers the panels coming off and going back, not the roof work underneath.
