Solar Workmanship Warranty vs Manufacturer Warranty: Which Is Right for Your Home
Written by HyreSolar Research Desk Primary-source research and fact checking
Quick answer
Solar Workmanship Warranty vs Manufacturer Warranty comes down to upfront cost, lifetime savings and how long you plan to stay in the home; here is each factor side by side.
You get both, and they cover different failures. Manufacturer warranties (product and performance) cover defective hardware and output decline, are written for the whole market and are backed by large companies.
The workmanship warranty is the installer’s promise that the installation itself (roof penetrations, racking, wiring) was done right.
It is the one that covers the most expensive failures, such as a roof leak, and the only one with no standard terms and no manufacturer behind it: it lasts exactly as long as the company that wrote it.
The warranties side by side
| Workmanship (installer) | Product (manufacturer) | Performance (manufacturer) | |
|---|---|---|---|
| Covers | The installation: penetrations and flashing, racking, conduit, wiring, terminations | Defects in the panel, inverter or other hardware | Output above a guaranteed share of rated power over time |
| Who writes it | Your installer, for your contract | The manufacturer, one document for the market | The manufacturer |
| Standard terms? | No. Anything from one to 25 years | Yes, published before you buy | Yes |
| Labor to remove and reinstall | Yes, if the contract says so | Excluded (Enphase §7.a; Qcells §5.c) | Excluded |
| If the issuer goes out of business | Usually ends; nothing backs it by default | Unaffected by the installer’s fate | Unaffected by the installer’s fate |
| Can a salesperson extend it verbally? | Only if written into the contract | No: no third party may modify it (Enphase §8; Qcells §6) | No |

If you hold an old Solar Roof quote or own one, the warranty questions are different: Tesla Solar Roof vs solar panels.
If this fails, who pays for what
| Failure | Who supplies the part | Who pays the labor |
|---|---|---|
| A panel is defective | Panel manufacturer | You, or the installer under workmanship |
| A microinverter dies | Inverter manufacturer | You, or the installer under workmanship |
| A roof penetration leaks | Nobody: it is not a part | The installer, under workmanship only |
| Racking works loose | Nobody | The installer, under workmanship only |
| Monitoring stops reporting | Often neither | Monitoring is commonly a service, not a warranted item |
Every failure that is the installation rather than a component lands on the one warranty with no manufacturer behind it.
The exclusion that points back at you
Manufacturers exclude bad installation. Qcells’ warranty does not apply to a system "of a design, configuration or installation that does not meet the standards typically used by experienced professionals in the industry"; Enphase excludes products "improperly installed, operated, handled or used."
Combine that with the labor exclusions and the risk is plain: if the installer did the job badly, the manufacturer can decline the claim, and the party responsible for fixing it is the installer whose work is blamed.
While the installer trades, you can make them answer. If it has failed, you hold a product warranty with an exclusion aimed at you and a workmanship warranty owed by nobody. See when your installer goes out of business.
The fourth warranty is your roof’s. Mounting an array puts dozens of holes through the roof. If a roofing warranty is voided, every later leak becomes a solar workmanship question by default.
Read your roofing warranty before the crew arrives, and ask for the contract to name roof penetrations and flashing as covered by the workmanship warranty.
What each is worth over 25 years
Manufacturer warranties protect the hardware you paid for, and their value does not depend on the installer surviving. But they ship parts, not labor, so even a valid claim can leave you paying for a roof visit.
The workmanship warranty protects against the most expensive failures, and its value is the issuer’s survival multiplied by its terms. A 10-year promise from a long-established, currently licensed company can be worth more than a 25-year one from a company formed last year.
California’s mandated Solar Energy System Disclosure Document covers total cost and the three-day right to cancel but no warranty terms; a separate CSLB form asks only for the contract page where warranty information appears.
Six questions that show what yours is worth
- 1Which legal entity gives the workmanship warranty?
The registered name, not the brand. Check it is licensed in your state (see national vs local installer).
- 2How long has that entity existed?
The best evidence about the next 25 years is the last ten.
- 3Does it transfer when you sell?
Automatic, on notice, for a fee, or not at all.
- 4What exactly does it exclude?
Weather, roof surface vs mount, other contractors’ work, and vague "failure to maintain" clauses.
- 5Does anything back it if the company stops trading?
Third-party warranty insurance or a manufacturer program: get the policy or program name and verify it.
- 6Who certifies the roof penetrations?
A licensed roofer gives you a second party with a stake in the waterproofing.
Making a claim without giving a reason to deny it
- 1Report it in writing, at once
Email, with what you saw and when.
- 2Photograph before anything is touched
Symptom, surroundings and serial numbers, timestamped.
- 3Do not let another contractor repair it first
Third-party work is a common exclusion; an emergency stopgap is easier to defend, and say why at the time.
- 4Name the warranty you are claiming under
And keep one email thread. Know your state licensing board before you need it.
