Understanding Solar Panel Product and Performance Warranties

By Sunlight Technology Solar Private Limited · Updated 21 October 2026

A product warranty and a performance warranty describe different commitments. Reading both helps customers understand the documents supplied with their equipment and the process they may need to follow if a concern appears later.

Identify who provides each warranty

Ask for the manufacturer’s written terms for the exact model and market. Confirm the warranty start conditions, registration requirements and exclusions. Also distinguish the equipment warranty from the installer’s workmanship or service arrangements; they should not be treated as interchangeable promises.

Understand the claim process

Keep invoices, model numbers and serial records. Ask who customers contact first, what evidence may be required and whether inspection, transport, labour or replacement work is included. A long warranty period is more useful when the responsibility and practical steps are clear.

Separate the remedy from the headline term

A product warranty concerns specified defects, while a performance warranty usually describes an output commitment under stated conditions. Neither automatically promises a fixed reduction in your electricity bill. Ask who receives a claim, what evidence is required and whether removal, transport and reinstallation are covered. Keep model and serial records with the invoice so a future claim can identify the exact supplied equipment.

Your practical checklist

• Obtain the full written terms
• Retain invoices and serial numbers
• Clarify costs and responsibilities during a claim

Does a long performance warranty cover every repair cost?

Read the document. Labour, shipping and installation work may have separate conditions or exclusions.
