Solar Panel Warranties Explained

Understand product, performance, workmanship and roof warranties before choosing a solar proposal.

THE DIRECT ANSWER

A residential solar project may involve several separate warranties: manufacturer product warranties, performance warranties, inverter or battery warranties and installer workmanship warranties. A provider-owned agreement may add service or production commitments. Each warranty covers different risks and may have different claim procedures.

01

A long term does not mean complete coverage

A warranty lasting many years may cover only specified defects or performance levels. Read exclusions, labor coverage, shipping, diagnostic costs and whether the warranty transfers to a future owner.

02

Workmanship and equipment are different

A manufacturer may cover a defective component while the installer covers roof penetrations or installation workmanship. Ask which company handles the first call and coordinates overlapping claims.

03

Provider service is contract-based

For TPO systems, the provider may be responsible for service during the agreement. Confirm response procedures, production obligations and what happens if the installer or original equipment manufacturer changes.

COMMON QUESTIONS

What homeowners ask next

Not always. A manufacturer performance warranty and a provider production guarantee can measure different things.

Does the roof warranty remain valid?+

Ask the roofer, installer and provider how penetrations and future roof work affect coverage.

Do warranties transfer when selling?+

Some do, subject to procedures and limitations. Review each warranty separately.
