How to Claim Solar Warranty in Pakistan: Complete Step-by-Step Guide (2026)

By PSI Editorial • June 8, 2026

Atomic Summary: To successfully claim a solar warranty in Pakistan, gather your original purchase invoice, warranty card, and video evidence of the fault. Contact the brand distributor or regional service center directly rather than depending solely on your installer. Claims are typically rejected if the system lacked proper surge protection or if modifications were made without authorization.

Your solar inverter just threw a cryptic error code, the screen is dead, or your panel output has dropped by half. You dial your installer and the phone rings endlessly. Sound familiar? This is the reality for thousands of solar owners across Pakistan who discover the hard way that buying a system is only half the battle, and getting after-sales support is the real test.

This guide walks you through the exact warranty claim process for solar panels and inverters in Pakistan, the documentation you need, the mistakes that void your warranty, and how to escalate when your installer disappears.

Understanding Solar Warranty Types

Before filing any claim, it is critical to understand what your warranty actually covers. Solar equipment in Pakistan typically comes with two distinct warranty categories:

Product (Manufacturing) Warranty

This covers defects in materials and workmanship. For solar panels, this is typically 10 to 12 years from Tier-1 brands like Jinko, Longi, Canadian Solar, and JA Solar. For inverters, brands like Solis, Growatt, Huawei, and Sungrow offer 5 to 10 year product warranties depending on the model.

Performance (Linear Degradation) Warranty

This guarantees a minimum power output over time. Modern N-Type TOPCon panels from brands like Jinko Neo and Longi Hi-MO X typically guarantee 87.4% output at Year 25 and up to 88.9% at Year 30. If your panels degrade faster than the warranty curve, the manufacturer must replace them.

Step-by-Step: How to File a Solar Warranty Claim

Step 1: Gather Your Documentation

This is where most claims fail. Without proper paperwork, no brand will entertain your request. You need:

• Original Purchase Invoice showing the dealer name, date, and equipment serial numbers.
• Warranty Card or Certificate (if the installer provided one at commissioning).
• Equipment Serial Numbers from the sticker on the back of the panel or the label on the inverter.
• Video or Photo Evidence showing the error code on the inverter display, physical damage to panels, or screenshots from the monitoring app (Solis Cloud, ShinePhone for Growatt, FusionSolar for Huawei).
• Commissioning Report documenting the installation date, system configuration, and string layout.

Alert: If you never received a warranty card, your purchase invoice becomes your only proof. Always photograph and store it digitally on the very first day.

Step 2: Contact Your Installer First

Your installer is legally your first point of contact. Send a written message (WhatsApp works, but also send an email or SMS for a paper trail). Give them 7 to 10 business days to respond. If they diagnose the issue and it is covered, they coordinate with the brand for you.

Step 3: Escalate to the Brand Distributor

If your installer is unresponsive, has shut down, or refuses to help, go directly to the brand. Major solar brands operating in Pakistan have authorized distributors with dedicated service desks:

Step 4: Technical Assessment

The brand service team will either visit your site or request remote diagnostics through the inverter monitoring app. They check whether the fault is a genuine manufacturing defect or caused by external factors such as improper installation, voltage spikes, or physical damage.

Step 5: Repair or Replacement

If approved, the brand will repair or replace the faulty unit. Important: Most warranties cover the equipment cost only. Labour, transportation, and crane charges for rooftop access are usually borne by the customer unless your installer contract explicitly covers them.

Top 5 Reasons Solar Warranties Get Rejected in Pakistan

• No Surge Protection Installed: Grid voltage spikes from WAPDA or K-Electric are extremely common. If your system lacked a Surge Protection Device (SPD) on both the DC and AC sides, the warranty is void. Read our guide on protecting your inverter from power surges.
• Grey Market or Unauthorized Equipment: Panels or inverters bought from unauthorized dealers may lack official warranty backing in Pakistan, even if the manufacturer offers a global 25-year warranty. Always verify the authenticity of your panels before purchase.
• Improper Installation: Incorrect string configurations, oversized or undersized inverters, wrong MPPT voltage window settings, or poor earthing can all void the warranty. Proper earthing of your solar system is mandatory.
• Physical Damage: Storm damage, hailstones, or accidental impact are not covered. This is considered an insurance matter, not a warranty issue.
• Unauthorized Modifications: Adding extra panels beyond the inverter capacity, changing wiring, or connecting a generator incorrectly will void your warranty immediately.

Special Case: Claiming Warranty When Your Installer Disappears

This is unfortunately common in Pakistan where hundreds of small solar companies started during the 2023 to 2025 boom and have since closed. Here is what to do:

• Register your warranty directly with the manufacturer as soon as possible after installation. Most brands like Jinko, Longi, and Growatt have online registration portals.
• Contact the brand distributor with your invoice and serial numbers. They can verify whether your equipment is genuine and process the claim directly.
• Hire an independent AEDB-certified solar technician to diagnose the issue and provide a third-party report, which strengthens your claim.
• File a complaint with NEPRA or your relevant DISCO if the issue relates to net metering equipment or grid-tie compliance.

Pro Tips to Protect Your Warranty From Day One

• Photograph all serial numbers, warranty cards, and invoices and store them in cloud storage.
• Install quality SPDs on both the DC panel side and the AC grid side. Expect to spend PKR 8,000 to 15,000 for proper protection.
• Register your warranty online with the panel and inverter manufacturer within the first 30 days.
• Set up monitoring through the inverter app (Solis Cloud, ShinePhone, FusionSolar) to catch issues early.
• Keep your panels clean and ensure the inverter filter is cleaned regularly so you are never blamed for neglect.
• Get a written contract from your installer that specifies labour coverage during the warranty period.

How Long Does the Warranty Claim Process Take?

Expect the following timelines in Pakistan:

Alert: During peak summer months (June to August), service centers are overwhelmed with claims due to voltage spikes from extreme grid load. File your claim as early as possible if you notice issues.

Conclusion

Claiming a solar warranty in Pakistan is not always straightforward, but it is absolutely possible if you are prepared. The key is documentation: keep every invoice, register every serial number, and maintain your system properly. If your installer vanishes, go directly to the brand. And above all, invest in surge protection from day one because it is far cheaper than a voided warranty on a PKR 200,000 inverter.
