Solar Panels Non-DCR vs DCR, Certificate, Warranty | Difference

Blog By Dheeraj Kumar. Terms like Non-DCR, DCR Certificate, and Warranty Certificate often confuse solar buyers. Many vendors don’t explain these properly, which later causes subsidy rejection, warranty issues, or compliance problems. This guide explains everything clearly so you can make the right solar decision.

What Is DCR in Solar Panels?

DCR (Domestic Content Requirement) means solar panels are
manufactured in India using Indian-made solar cells and modules,
as per MNRE (Ministry of New & Renewable Energy) guidelines.

Why DCR Exists

Promote Indian solar manufacturing
Reduce dependency on imports
Ensure quality control in subsidized projects

What Are DCR Solar Panels?

Manufactured in India
Use Indian solar cells
MNRE-approved
Mandatory for subsidy projects

Without DCR panels, government subsidy claims can be rejected.

What Are Non-DCR Solar Panels?

Non-DCR panels may be imported or partially imported and are commonly used in
commercial or private projects where subsidy is not required.

Used in commercial & industrial projects
Often higher efficiency options available
Not eligible for government subsidy

DCR vs Non-DCR Solar Panels

Parameter	DCR Panels	Non-DCR Panels
Manufacturing	India	India / Imported
Subsidy	Yes	No
MNRE Approval	Mandatory	Not Required

What Is a DCR Certificate?

A DCR Certificate confirms that the installed solar panels
meet MNRE’s Domestic Content Requirement norms.

Required for subsidy disbursement
Checked during DISCOM inspection
Issued by the panel manufacturer

Missing DCR certificate = possible subsidy cancellation.

What Is a Solar Warranty Certificate?

Panel Performance Warranty: 25 years
Panel Product Warranty: 10–12 years
Inverter Warranty: 5–10 years
Structure & Workmanship Warranty

Common Solar Buyer Mistakes

Using Non-DCR panels for subsidy projects
Not demanding DCR certificates
Accepting verbal warranty promises
Mixed or undocumented components
