Frequently asked questions

The installer’s workmanship (labor) warranty usually ends with the company unless a buyer took it on. Equipment warranties from the panel, inverter and battery makers are separate and often still apply.

SolarEdge, for example, says that even if the installer has ceased operations, “certain components might still be covered.” Labor to swap a part is often not covered.

Some licensed California contractors say on their own websites that they service systems installed by other companies. Our installer page lists them, with their quotes and links. We don’t promise any of them will take your job, so ask, and check the license at the CSLB first.

Contractors that say they service other installers’ systems →

1. Find your paperwork: contract, permit, and the brands of your panels, inverter and battery (on the labels or in the monitoring app).
2. Look up the company: was it bought, or did it file bankruptcy? Our brand pages link the official notices.
3. Lease, PPA or loan? Call the company you pay each month first.
4. Check the maker’s warranty for failed equipment. The maker may cover the part even though the installer is gone.
5. Get control of your monitoring account. Some installers keep it; one listed contractor says it can transfer the Enphase Enlighten account to you.
6. If you hire a contractor, choose a licensed one and check the license at the CSLB.

If you pay a monthly lease or PPA bill, call whoever you pay. For SunPower, SunPower Inc. says it didn’t take over customer PPAs or leases, and SunStrong Management is the servicer for many legacy SunPower and Sunnova leases and PPAs. SunPower Inc. says to contact your financier or SunStrong Management.

If you have a loan, who now holds it is a separate question from who owns the panels.

Some installers keep the monitoring account. One California contractor we list says: “We can transfer the Enlighten account to your ownership and perform all maintenance and repairs regardless of who originally installed the system.” That is its own claim, not a promise from us; ask any contractor whether they can do this for your brand.

The original SunPower Corporation filed Chapter 11 on Aug 5, 2024 and wound down. A different company, SunPower Inc. (formerly Complete Solaria), bought some of its assets; that sale closed Sept 30, 2024.

Installer’s labor warranty: SunPower Inc. says its purchase “did not include taking any interest in … any solar systems … that was installed prior to” Sept 30, 2024. So for an older system, don’t count on the old installer’s labor warranty. SunPower Inc. says systems installed by its Blue Raven Solar or Complete Solar brands keep their installation-agreement warranties.

Equipment warranty: Panels, inverters and batteries carry the maker’s warranty, separate from the installer. SunPower Inc.’s warranty page lists maker contacts (for example Enphase, Qcells, REC and Fronius). Labor to swap a part is often not covered.

Lease or PPA? SunPower Inc. says to contact your financier or SunStrong Management.

Sunnova filed Chapter 11 on June 8, 2025 and sold its assets in court-supervised sales. Sunnova says it “has ceased independent operations” and that SunStrong Management now services “most in-service customer systems.”

Installer’s labor warranty: If you have a Sunnova lease, PPA or loan, Sunnova says SunStrong Management took over servicing for most in-service systems — ask SunStrong in writing what your contract covers. Many Sunnova systems were sold and installed by local dealers (Sunnova’s own closure page refers to “your dealer”), so check who actually installed yours.

Equipment warranty: Panels, inverters and batteries carry the maker’s own warranty, separate from Sunnova or the dealer. Find the brand on the equipment label or in your monitoring app.

Lease, PPA or loan: start with SunStrong Management.

Freedom Forever, a Temecula, CA installer, filed Chapter 11 on Apr 15, 2026. With no buyer or sponsor, the case was converted to a Chapter 7 liquidation on Aug 7, 2026, and a trustee was appointed to wind down what’s left.

Installer’s labor warranty: A company in Chapter 7 liquidation isn’t doing warranty work. pv magazine reports the deadline for customers with deposits or warranty claims to file a proof of claim was Oct 16, 2026 — that date has passed. The court’s case site is linked below. Not legal advice — read your own contract.

Titan Solar Power, based in Chandler, Arizona, ceased operations and filed for Chapter 7 bankruptcy on June 20, 2024.

Installer’s labor warranty: Chapter 7 means the company is liquidated, so its labor warranty is very unlikely to be honored. Not legal advice — read your own contract.

Lumio filed Chapter 11 in September 2024 to sell its business. Zeo Energy announced on Nov 6, 2024 that it had completed the sale transaction with Lumio.

Enphase makes microinverters, batteries and the Enlighten monitoring app. It’s a manufacturer, not an installer — and it’s still in business.

Installer’s labor warranty: Enphase doesn’t give a workmanship warranty. That came from whoever installed your system. If that company closed, its labor warranty most likely went with it.

Equipment warranty: Enphase publishes its U.S. limited warranties by product on its warranty page, including how a warranty transfers when a home is sold. Its support site has an article on finding a new installer if yours went out of business. Ask any contractor whether they can file the warranty claim for you.

SolarEdge makes inverters and power optimizers. It’s a manufacturer, not an installer.

Installer’s labor warranty: SolarEdge doesn’t give a workmanship warranty. That came from your installer, and likely ended if the installer closed.

Equipment warranty: SolarEdge says its inverters “come with a warranty period of 12 to 25 years” and that even if the installer closed, “certain components might still be covered.” It also offers a paid system health check.

Prepaying doesn’t by itself make you the owner. The CPUC notes that leases and PPAs can be set up in different ways, “such as paying more up front to reduce your monthly payments.” The CSLB’s supporting-information form even has an “Upfront payment, if applicable” line in its PPA box.

So the question is what kind of contract it was (purchase, lease or PPA), not whether you paid in advance. Find the contract’s end-of-term section. California law requires lease and PPA disclosures to include a plain-language explanation of what happens to the system at the end of the term. If your contract says you get the system at the end, that is where it will say so.

Quick check by contract type →

The solar provider owns the system in a lease or PPA. The CPUC: “With a lease, the solar provider owns the system and ‘rents’ it to you,” and in a PPA “the solar provider owns the system on your property and sells you the electricity it generates.” With a cash or loan purchase, or PACE financing, you own the system.

Owning it and owing money on it can both be true. The CPUC notes that a secured loan uses an asset as collateral, “often that asset is your solar system.”

Sources: CPUC, “California Solar Consumer Protection Guide” (overview & FAQ; version 4) · CSLB, Solar Energy System Supporting Information (version 2) · CSLB, “Solar Smart”

Who owns my system? →

Look for the CSLB Solar Energy System Disclosure Document on the front of the contract and the Supporting Information pages behind it. The latter has a PPA/lease section (“Customer will not own system”) and a purchase section (“Customer will own system”).

If the installer never gave you these, the CPUC says to ask for them, and to report a provider that won’t provide them to the CSLB. With the installer gone, ask your lender or the company you pay each month.

Sources: CSLB, Solar Energy System Disclosure Document (cover page, Form 13L-6) · CSLB, Solar Energy System Supporting Information (version 2) · CPUC, “California Solar Consumer Protection Guide” (overview & FAQ; version 4)

Four places to check, in order →

Since a 2018 CPUC decision (D.18-09-044), solar providers must upload the signed pages of the CPUC consumer guide, the installation contract and the CSLB disclosure document to the utility before connecting a home in PG&E, SCE or SDG&E territory. So your utility may hold a copy of your contract. Ask its solar or customer-generation team what it can send you for your address; we haven’t confirmed each utility’s process.

A Permission to Operate (PTO) letter shows the system was approved to run. It isn’t a title document.

It’s a clue, not proof. Monitoring accounts are separate from ownership of the equipment. Having the login doesn’t make you the owner, and not having it doesn’t mean you aren’t.

A UCC “fixture filing” goes where mortgages on the property are recorded, which is the county recorder. Other financing statements go to the Secretary of State, which offers online UCC inquiry services. Los Angeles County, for example, records UCC financing statements in the county when real property is affected, but it says it has no online access to its real-estate records, which are viewed by appointment. Search by your name, your address and the year of installation. Counties differ, so check yours.

A fixture filing tells you someone claims a security interest in the equipment. By itself it doesn’t tell you who owns the panels. Finding nothing isn’t proof either way.

County recorder and Secretary of State →

A provider that leases a residential system or sells you its power must record this notice with the county recorder within 30 days of signing. It says the provider “has retained ownership” of the system, and lists the provider’s name, address and phone, whether it’s a lease or a sale of electricity, and the start and end dates. The law says the notice is not a lien or encumbrance, and the provider must record a document ending it when the contract ends or transfers.

Sources: California Public Utilities Code §2869 (leases and PPAs for residential solar)

How to read what you find →

We couldn’t confirm that. We found no official source on what happens to ownership if a lease or PPA provider goes bankrupt. That depends on the contract and the bankruptcy. Check the brand page for your company and your own contract, and ask a lawyer if a lot of money is at stake.

California companies publish prices from about $80 to $350 per panel: Forme Solar $350, Grandmark Roofing $250–$350 standalone (less when bundled with a roof), Home Pro $200–$350 depending on the page, California First Roofing “commonly $80–$175.” EnergySage’s benchmark, cited by OC Solar, is $200–$300 per panel.

This is general market information, not a quote or price from any contractor. Your price depends on panel count, roof type, and whether racking or flashing must be replaced. Get a written quote.

• Check the contractor’s license is active at the CSLB.
• Ask whether removal, storage, reinstall and re-commissioning (turning it back on and testing) are all in the quote.
• Ask who warrants the roof penetrations afterwards: the roofer or the solar contractor.
• Get the panel work scheduled together with the roofer, so the roof isn’t left open.

Tesla says to submit the reinstall request after the roof work is complete, and that the roof must sit for 30 days with no additional work before reinstallation can begin. The date tool on our Tesla page is a simple 30-day count. Tesla’s follow-up, permits and scheduling come on top of it.

Sources: Tesla Support, “Removal and Reinstallation” (solar panels)

Date tool: when can I request the reinstall? →

1. Request removal. Removal and reinstall are two separate requests. Each needs its own Service Work Agreement and invoice, and removal must be completed before you can submit the reinstall request.
2. Wait for the follow-up and permits. Tesla says it follows up on each request within about seven to ten business days. If permits are needed, that step can take up to two months on average.
3. Store the panels, do the roof. You must provide a safe place to store the removed panels.
4. Let the new roof sit 30 days, then submit the reinstall request.

Tesla’s page doesn’t give a price. It says to see your energy contract for pricing.

Tesla says third-party contractors may be used without its approval of the contractor or scope of work, but it recommends you review your system’s limited warranty first. Tesla isn’t responsible for a third-party contractor’s workmanship; your existing system warranty may be voided; and your energy contract stays active, so you still owe monthly payments while the panels are off.

For California Tesla lists composition shingle, concrete flat tile and concrete round tile (pitch 9.5° to 45°), standing seam metal (0° to 45°) and rolled torch down (0° to 9.5°).

The CPUC says people who take a solar loan or sign a lease or PPA receive a monthly bill from the loan company or solar provider, and they still get a utility bill. “You will never pay an electric bill again” is one of the false claims the CPUC lists.

The sun isn’t always shining, so most solar customers still rely on the grid. After going solar you typically pay a reduced bill every month and may owe a larger one at the end of the 12-month cycle. SCE says solar credits can reduce certain charges, but fixed fees, non-bypassable charges and taxes can’t be reduced by them. That’s SCE’s rule; check your own utility’s bill explainer.

Sources: CPUC, “California Solar Consumer Protection Guide” (overview & FAQ; version 4) · SCE, “FAQs about the Solar Billing Plan”

Why you still get a utility bill →

• Cash or loan: you own it; you pay cash up front or a loan payment; you are typically responsible for repairs and maintenance.
• Lease: the provider owns it; a scheduled monthly payment over a set number of years (typically 20 to 25); the provider is responsible for monitoring, maintenance and repairs.
• PPA: the provider owns it; a per-kWh rate for the power the system generates; the provider maintains it.
• PACE: you own it; a payment on your property tax bill; you are typically responsible for repairs and maintenance.

“Provider is responsible” only helps if the provider still exists. The CPUC lists “solar provider could go out of business during the contract period” as a downside of leases and PPAs.

Sources: CPUC, “California Solar Consumer Protection Guide” (overview & FAQ; version 4)

The four ways people pay for solar →

Lease and PPA payments typically rise by a set amount each year, called an escalator. The CPUC says escalators are typically 1 to 3 percent above the previous year and to be cautious of a higher one. The CSLB likens a PPA’s escalator clause to a variable-rate mortgage that goes up every year. Look in the supporting-information pages of your contract for yours.

The net billing tariff (the Solar Billing Plan, which the CPUC says is colloquially called NEM 3) applies to customers who applied to interconnect on or after April 15, 2023. Your solar first covers your own use. Exports earn credits, and extra credits roll forward until the annual true-up. The CPUC says the credit for exported power is usually lower than the retail rate, but can rise above it on late summer evenings.

Tesla’s Powerwall 3 design-considerations page says backup systems must be 120/240 V single/split-phase service only. We found no Tesla document in what we read that approves a workaround for 120/208 V, so get confirmation in writing from Tesla or your installer before you pay for the equipment. The guide’s line is about backup systems; we didn’t find what it says for a grid-tied battery with no backup.

Powerwall 3 on 120/208 V →

• A grid connection is required. Fully off-grid isn’t supported.
• Only Tesla’s own tie-in devices (Backup Switch, Backup Gateway 2 or Gateway 3) work. No third-party substitutes.
• The Backup Switch design covers service up to 200 A with a Form 2S meter socket.
• Solar input is limited to 20 kW DC. Third-party module-level power electronics (such as optimizers) wired to Powerwall 3 are listed as not compatible.
