Long-term generation assurance
On-Grid Solar Assurance
25+ Years Panel Performance Warranty
Understand what long-term solar panel performance warranty means, what documents to keep, and how component selection affects on-grid solar output.
Module datasheet and serial tracking
ALMM relevance where applicable
What Research Shows
1
Performance warranty is different from product warranty
Panel performance warranty generally relates to expected generation over time. Product warranty, physical damage, workmanship, and service response should be checked separately in the proposal.
2
Module traceability matters
A good handover should preserve module make, model, wattage, warranty sheet, invoices, and serial-number records so future service or warranty requests are easier.
3
Component compliance should be checked before procurement
MNRE maintains ALMM information for approved solar module models and manufacturers. Applicability depends on the project category and current government rules.
Buyer Questions
Does 25 years mean every part is covered for 25 years?
No. Panel performance warranty, panel product warranty, inverter warranty, structure warranty, and installation warranty are usually separate terms.
What should I ask before approving panels?
Ask for module make, model, wattage, datasheet, warranty terms, serial-number records, and whether ALMM applicability is relevant for your project.

Inverter Warranty
The on-grid inverter synchronizes solar power with the grid, so warranty, monitoring access, protection devices, and service terms should be clear.
