How to Claim Your Solar Panel Warranty in India — Step-by-Step Process

Understanding Your Solar Panel Warranties

When you install a rooftop photovoltaic system, the hardware comes with two distinct types of protection. Navigating the solar panel warranty claim process requires knowing which category your issue falls under. Manufacturers split their coverage into a product warranty and a performance warranty.

The product or manufacturing-defect warranty typically lasts for 10 to 12 years. It covers physical flaws, premature wear, junction box failures, and internal circuit issues. The second category is the linear performance warranty, which usually runs for 25 years. This specific guarantee promises that your panels will retain a specific output capacity, ensuring they still produce roughly 80 percent of their rated power by the end of year 25.

Your Installer as the First Point of Contact

Homeowners often try to contact the multinational component manufacturer directly when a fault appears. However, the standard protocol in India is to reach out to your original installation vendor first. Installers maintain direct channels with regional distributors and factory representatives.

Your installer will visit the site to check if the fault stems from the wiring, the inverter, or the panel itself. If the hardware is genuinely defective, the vendor compiles the technical logs and raises the formal paperwork with the maker. Working through your installer speeds up the inspection and prevents common administrative delays.

Essential Documents Required for a Claim

You cannot initiate a claim without proper paperwork. Manufacturers reject requests lacking proof of purchase and installation records. Gather these files before calling your vendor:

• Original purchase invoice showing the panel serial numbers
• Manufacturer warranty card provided at commissioning
• Commissioning report or installation completion certificate
• Photographs or video proof of the physical damage or output drop

Store physical copies in a safe folder and keep digital scans on your phone or computer. Without these records, proving the age and ownership of the hardware becomes difficult.

What Happens After Filing the Claim

Once your installer submits the paperwork and diagnostic logs to the manufacturer, a technical review begins. The manufacturer verifies the serial numbers and assesses the failure type. If the claim is approved, the company arranges for a technician to visit your roof to replace the faulty unit or repair the affected modules.

Keep in mind that logistics and replacement availability dictate how quickly the physical swap occurs. Maintain regular communication with your installer during this review period to track the status of your replacement hardware.
