Solar is a long-term investment, and warranties are how that investment is protected. A typical system carries several layers of coverage — panel, inverter, battery, and the installer's workmanship — each with its own terms. This page explains the types of solar warranties, what each one covers, and what to verify before you sign, so you can compare proposals with confidence. We don't promise specific coverage numbers here; instead, we point you to the official documents where the real terms live.

Terms vary by manufacturer, series, and registration. Always confirm the current details in the official warranty documents before relying on any coverage period.
Coverage is one reason panel and inverter brand matters. Premium brands such as REC and Qcells publish their own product and performance warranties, and Enphase microinverters carry separate inverter coverage. When we compare equipment with you, warranty terms sit alongside efficiency, appearance, and budget. See the solar panel brands comparison for a side-by-side view.
Manufacturer warranties cover the equipment; a workmanship warranty covers the installation. As your licensed contractor, we stand behind our work, and a protection plan can add another layer for peace of mind. Keeping up with simple maintenance and watching monitoring also helps you catch issues while they're still covered.
A strong solar proposal should make warranty responsibility clear before the project starts. Ask for the current manufacturer PDFs, the installer workmanship terms, monitoring access details, and the process for service after activation.
| Warranty item | What to confirm |
|---|---|
| Solar panels | Product defects, performance terms, registration requirements, exclusions, and transfer rules. |
| Inverters or microinverters | Separate warranty term, monitoring requirements, replacement process, and labor responsibility. |
| Battery storage | Capacity retention, cycle or throughput rules, backup limitations, and monitoring requirements. |
| Workmanship | Roof penetrations, flashing, wiring, labor coverage, service-call process, and what is excluded. |

Request a Free EstimateCall (833) 446-6387Solar systems typically carry several layers of coverage: a panel product warranty, a panel performance warranty, an inverter warranty, a battery warranty if installed, and a workmanship or labor warranty from the installer. Terms vary by manufacturer and series, so always confirm the current details in the official documents.
A product warranty covers defects in the panel itself, while a performance warranty addresses how much output the panel is expected to retain over time. They are separate coverages with their own terms, which we help you review for the equipment in your proposal.
Usually yes. Inverters and microinverters carry their own warranty, which can differ in length from the panel coverage. Because inverters have a shorter service life than panels, the inverter warranty is worth understanding closely.
A workmanship or labor warranty covers the quality of the installation itself, separate from the equipment manufacturers' warranties. As your licensed installer, we stand behind our work, and we can explain how workmanship coverage and a protection plan fit alongside the manufacturer warranties.
