Solar Panel Warranties in India: How to Make a Claim

Posted by Waaree Waaree on 24th Feb 2026

The process for filing a solar warranty claim in India typically begins with reporting an issue with the solar panel to either the manufacturer or the installer. Next, you must provide them with all relevant documentation regarding the solar panel, including proof of purchase and installation, and allow the solar company to inspect the solar panel or the entire solar system. After confirmation of the defect, the company that sold you the solar panel will provide interpretation in accordance with the terms of the warranty and will typically provide repair or replacement of the defective solar panel.

What Are the Terms of a Solar Panel Warranty?

Solar Panel Warranties provide certain guarantees made by the solar panel manufacturers and/or installers to protect your investment in solar energy. They ensure that the solar panels will produce the amount of energy promised to you and that they will not have any defects that would be the result of the manufacturing process, either during their original manufacture or after they have been installed.

The warranties on most solar panels cover two important elements of the solar system:

Product Warranty: Covers the hardware and defects in manufacturing or materials used to produce the solar panel.
Performance Warranty: Provides a guarantee of output over a defined period of time.

The typical solar panel warranty for a solar panel and/or solar system warranty ranges from a minimum of 10 to a maximum of 15 years. Performance warranties for a solar panel or solar system last up to 25 years or longer. There is a direct relationship between these two warranties. Assuming that the solar panel receives proper maintenance, the useful life of the solar panel should be longer than 20 years, reflecting the typical solar panel lifespan.

The effectiveness and duration of these warranties provide solar panel warranty coverage against unexpected malfunctions as well as loss of performance over time.

What Is Covered in a Warranty on Solar Panels

While different manufacturers provide solar panel warranty policies that offer different types of coverage, there are commonalities between many of the warranties.

1) Manufacturing Defects

Coverage for the following types of manufacturing defects:

Defects in the frame or junction box
Manufacturing defects in glass
Manufacturing defects for delaminated cells or cells

2) Degradation of Performance

Manufacturers generally provide performance guarantees that require, for example:

Approximately 90% after 10 years
Approximately 80% after 25 years

Performance guarantees provide the foundation for reliable solar warranty policies and help ensure that solar panels will produce reliably for the life of the panel.

Steps to File a Claim Against Your Warranty for Solar Panels in India

Understanding how to file solar warranty claims in India can assist owners of systems to respond in an efficient manner when issues arise.

Step 1 – Recognising the Problem

Common reasons to file a solar warranty claim are generally due to the following issues:

Loss of power generation for no apparent reason
Issues related to the system that are not normal
Manufacturing defects of the solar panel or components

Prior to contacting the manufacturer of your system for warranty support, you can examine your system's details through Waaree's official support module or through installation support.

Step 2 – Contact Installer or Manufacturer

You should contact the installer if there are problems with the installation of the system, or the manufacturer if there are defects in the solar panels or components. Your installer or manufacturer will provide directions on how to claim a solar panel warranty based on the configuration of your solar panels.

Step 3 – Provide the Required Documentation

You will generally be required to provide the following documents:

An invoice documenting your purchase
Certificate of Warranty
Report documenting the installation of your system
Serial number of the solar panels

Documenting your solar warranty claims in India accurately will help expedite the processing of any claims against warranties.

Step 4 - Verification and Inspection

The manufacturer or installer will use several methods to verify that a claim is valid, including:

Conducting remote performance diagnostics
Coordinating an on-site inspection if needed

These actions will determine if the claim meets the requirements of the solar panel warranty or the solar system warranty.

Step 5 - Resolution

Multiple options are available under the warranties:

Repair or replacement of defective solar panels
Offering compensation for poor performance

Once completely verified, the warranty claim will be completed with regard to the solar warranty.

Common Reasons Why Warranty Claims Are Denied

Many solar warranty claims in India are denied for reasons that could have been avoided, such as:

Improper Installation

Installing solar panels incorrectly will void their manufacturer’s solar panel warranty under many manufacturers' rules.

Lack of Proper Documentation

Missing invoices and warranty cards can prevent the submission or expedite claims for solar panel warranty coverage.

Poor Maintenance Practices

Inadequate solar panel maintenance practices will often void any solar system warranty.

Damage from Outside Sources

Storms, accidents or mishandling of solar panels by anyone other than the manufacturer will probably not be covered by warranties of any kind.

Best Practices for Successful Solar Panel Warranty Claims

To simplify the process for claiming solar panel warranty support, keep the following tips in mind:

Use a reputable solar panel manufacturer that has a solid reputation for meeting solar warranty commitments.
Ensure installation of your solar panels is performed by qualified installers recognised by the manufacturer.
Store all paperwork related to the sale or installation of your solar panel system in a secure location.
Perform regular solar panel maintenance at least annually.
Watch for significant drops in the performance of the solar panel system at any time.

Tips for Maintaining Your Solar System Warranty Protection

To help you fully utilise your solar system warranty:

Keep the solar panels clean on a regular basis to reduce dust build-up.
Plan for yearly inspections of your system.
Use automated tools to monitor energy production from the equipment.
Never make unapproved repairs or alterations to the equipment.

Taking proper care of this equipment will ensure that your solar warranty remains valid for the life of the project.
