I have checked and verified that the Solar Panel Warranty Claim Process in Pakistan is very simple because we need to show our warranty invoice when purchasing solar panels in shops or retailers. For a warranty claim, we need to buy Tier 1 solar panels or A-Grade solar panels because these companies immediately claim their solar panels.
There is 12 years product warranty and 25 years performance warranty in Pakistan on solar panels Tier 1 like Longi, Jinko, Trina, Inverex, JA, and Canadian. Top Solar panel companies immediately change their solar panels when any issues or problems occur.
Important Notice: These companies always claim their solar panels when there are issues with solar panel performance, but not when solar panels break due to heavy winds, storms, or snowfall. Tier 1 solar panels have a potential rate of almost 25%, which means that they generate huge amounts of solar energy or electricity.
Me Personal experience: It is also important that Warranty culture is improving as competition increases and consumers become more informed. Always buy and install A-grade solar panels because their performance is best for generating more energy for 25 years.
What Is a Solar Panel Warranty and Why Does It Matter in Pakistan?
It is important to note that A solar panel warranty is a legally binding commitment from the manufacturer or installer that your system will perform within specific limits for a defined period.
In Pakistan, where consumers often lack awareness of their rights and brands sometimes dodge accountability, knowing your warranty terms before buying is not optional.
It is also informative news that Solar panels are a significant investment. A quality 10kW system can cost between PKR 800,000 and PKR 1,500,000 in Pakistan in 2026
My personal tip: Without warranty protection, any malfunction or degradation could mean replacing panels entirely out of your own pocket.
The Two Core Types of Solar Panel Warranties in Pakistan
There are two core types of Solar Panel Warranties in Pakistan, and here we will discuss them one by one as follows.
1. Product Warranty (Manufacturer’s Warranty)
This warranty covers physical defects in the panel itself, things like delamination, frame corrosion, broken glass, cell cracking, junction box failure, or manufacturing faults. In Pakistan, most reputable brands offer a 10 to 15-year product warranty, though budget brands from China may only offer 5 years.
2. Performance Warranty (Power Output Warranty)
This warranty guarantees that your panels will produce electricity at or above a certain percentage of their rated capacity over time. The industry standard is:
- Year 1: No more than 2–3% degradation
- Years 2–25: No more than 0.5–0.7% degradation per year
- Year 25: At least 80–82% of the original rated output
Top Common Solar Panel Problems That Qualify for a Warranty Claim
There are also some Top Common Solar Panel Problems That Qualify for a Warranty Claim, and here we will discuss them.
Physical Defects Covered Under Product Warranty
- Delamination: The protective film separating from the cell surface, usually appearing as bubbles or cloudiness in the panel
- Microcracks in solar cells: Often invisible to the naked eye, but detectable through thermal imaging
- Hotspots: Localized overheating due to cell faults, often visible as discoloration
- Junction box failure: The small black box on the back of the panel stops functioning, cutting the output
- Frame damage not caused by external force: Corrosion, bending, or cracking without storm or accident involvement
- Backsheet yellowing or cracking: The back surface of the panel deteriorates prematurely
Performance Issues Covered Under Performance Warranty
- Measurable output falling significantly below the warranted degradation curve
- Multiple panels consistently generate 20–30% less than expected under standard test conditions
- Sudden unexplained drop in system output not related to shading, inverter fault, or wiring issues
What Is NOT Covered
This is where many Pakistani consumers get tripped up. Standard warranties typically do not cover:
- Damage from storms, hail, floods, or fire (covered under home insurance, not panel warranty)
- Physical damage caused during installation (installer’s liability)
- Theft or vandalism
- Performance loss caused by shading from trees or new construction
- Improper installation by an uncertified installer
- Use of incompatible inverters or wiring
- Panels cleaned with abrasive materials or harsh chemicals
Understanding Which Party Is Responsible for Your Claim
In Pakistan, warranty claims can get confusing because multiple parties are involved. Knowing who is responsible for what determines where you send your complaint.
The Manufacturer
International brands like JA Solar, Longi, Canadian Solar, Jinko Solar, and Trina Solar have authorized distributors in Pakistan. Your product or performance warranty claim ultimately goes back to the manufacturer — but you usually deal with their local representative.
The Local Distributor or Importer
There are also many Companies like Reon Energy, SolarMax Pakistan, Tesla Energy Pakistan (not affiliated with Tesla USA), and dozens of others that import panels and take on warranty obligations locally. If the manufacturer is a Chinese company without a Pakistan office, the distributor is your primary point of contact.
The Installer or EPC Contractor
Installation warranties — separate from panel warranties — are the contractor’s responsibility. If your racking is rusting, your wiring is done wrong, or your system was never producing at the right capacity from Day 1, that is likely an installation issue, not a panel defect.
Step-by-Step Solar Panel Warranty Claim Process in Pakistan
There are we well discuss the Step-by-Step Solar Panel Warranty Claim Process in Pakistan.
Step 1: Gather All Your Documentation First
Do not contact anyone until you have the following in hand:
- Original purchase invoice with panel model number, serial numbers, and wattage
- Installation date and installer’s details
- Warranty card (if provided — many Pakistani distributors are poor at issuing these)
- System monitoring data if your inverter has a monitoring app (Solis, Huawei, Growatt, etc.)
- Photos and videos of the defect or problem
If you do not have all of this, start gathering it now. Claims without documentation are almost always rejected or delayed indefinitely.
Step 2: Identify the Defect and Document It Thoroughly
Take high-resolution photographs of:
- The defective panel(s) — close-up and wide-angle
- The serial number sticker on the back of each affected panel
- Any visible damage, discoloration, delamination, or cracking
- Your inverter display is showing reduced output (if a performance issue)
If you suspect a performance issue, download at least 3–6 months of generation data from your inverter’s monitoring portal.
Compare it against the expected generation for your location using tools like PVGIS (EU-funded free tool) or the PVWatts calculator.
Step 3: Contact Your Installer First
Your first call should be to the company that installed your system. They often handle the initial claim process on your behalf since they have a direct relationship with the distributor. They will:
- Send a technician to inspect the system
- Confirm whether the issue is a panel defect or an installation/wiring problem
- Initiate a claim with the distributor if a panel defect is confirmed
Important: Get everything in writing. Do not accept verbal promises. Send a formal email or WhatsApp message (screenshot it) stating the issue, the date, and what they promised.
Step 4: File a Formal Written Complaint with the Distributor
If your installer is unresponsive or the issue is clearly a manufacturing defect, contact the brand’s authorized distributor in Pakistan directly. Your written complaint should include:
- Your full name, address, and contact number
- System installation date and location
- Panel brand, model, and serial numbers of the defective panels
- Detailed description of the problem
- Copies of the purchase invoice and any warranty documentation
- Photos and monitoring data attached
Send this via email (so you have a timestamp and paper trail). Follow up with a phone call the same day.
Step 5: Allow the Inspection Process
Reputable companies will send a qualified technician to inspect your system. This inspection may involve:
- Visual inspection for physical defects
- Irradiance measurements using a solar meter
- IV curve tracing to test each panel’s electrical output
- Thermal imaging (infrared camera) to detect hotspots or microcracks
Be present during this inspection. Take your own photos and notes. Ask for a written inspection report.
Step 6: Review the Inspection Report and Claim Decision
After inspection, the company will issue a report either approving or rejecting your claim. If approved, they will typically offer:
- Replacement panels (most common resolution)
- Repaired panels (rare and generally not recommended for performance-critical applications)
- Partial compensation (if only part of the panel population is affected)
If rejected, they must give you a written reason. Common rejection reasons in Pakistan include:
- Claiming damage is due to “external factors” (storms, accidents)
- Claiming improper installation voids the warranty
- Serial number mismatch or missing documentation
Step 7: Escalate If Your Claim Is Wrongly Rejected
If you believe your claim was rejected unfairly, you have several escalation options in Pakistan.
How to Escalate a Rejected Solar Warranty Claim in Pakistan
It is also very important that getting a rejection is not the end of the road. Pakistan’s consumer protection landscape is improving, and you have real options.
Option 1: Contact the Manufacturer Directly
- Most major panel brands have regional offices or global customer service portals.
- Longi Solar, JA Solar, and Canadian Solar all have formal complaint channels.
- Submit your complaint with all documentation and the local distributor’s rejection letter.
- Manufacturers sometimes override their distributors, especially when the defect is clearly a product issue.
Option 2: Consumer Courts and Consumer Protection Councils
Under Pakistan’s Consumer Protection Acts — including provincial laws in Punjab, Sindh, KPK, and Balochistan — you can file a complaint against a vendor for selling a defective product. Consumer courts are relatively accessible and do not always require a lawyer for small to medium claims. File at:
- Punjab Consumer Protection Council (Lahore)
- Sindh Consumer Protection Council (Karachi)
- KPK Consumer Court (Peshawar)
You will need your purchase invoice and written evidence of the company’s refusal to honor the warranty.
Option 3: AEDB (Alternative Energy Development Board) Complaints
The AEDB registers solar companies and installers. If a registered company refuses to honor a warranty, you can lodge a formal complaint with AEDB. While AEDB’s enforcement power is limited, the complaint creates an official record and can put pressure on the company.
Option 4: Social Media and Industry Forums
Pakistani solar consumers are increasingly using platforms like Facebook solar energy groups, Twitter/X, and LinkedIn to publicly document warranty disputes. Major brands are sensitive to reputational damage, and a well-documented public complaint sometimes moves faster than formal channels.
Warranty Claim Tips Specific to Pakistan’s Market
The Pakistani solar market has some unique characteristics that affect how warranty claims play out. Solar Panel Price in Pakistan After Budget 2026: Latest Rates
Verify the Warranty Before You Buy
Pakistan has a significant problem with grey market panels — panels imported without proper documentation, often with counterfeit or manipulated serial numbers. A warranty claim on a grey market panel is essentially worthless because the manufacturer will not recognize the serial number.
Before purchasing, ask your supplier to show you:
- The original manufacturer’s invoice or packing list showing the serial numbers
- Proof of import (customs declaration)
- The manufacturer’s official warranty terms (downloadable from the brand’s website)
Work Only with AEDB-Registered Installers
Hiring an unregistered installer not only risks poor workmanship — it can also void your panel warranty. Many manufacturers explicitly state that their warranty is only valid if the system was installed by a certified professional. AEDB maintains a registry of registered solar companies.
Register Your Panels Online
Many major brands — Longi, JA Solar, Canadian Solar — offer online warranty registration portals. Registering your panels creates an official record with the manufacturer, independent of the local distributor. If there is ever a dispute, this registration works in your favor.
Keep Records for the Full Warranty Period
Do not throw away invoices after a few years. A 25-year performance warranty means you may need that original invoice in 2040. Store physical and digital copies in a safe place.
Monitor Your System’s Output Regularly
Performance warranty claims require data. If your inverter has monitoring capability (most modern inverters from Huawei, Growatt, Solis, and Fronius do), check your generation data monthly and compare it against expected figures for your location and panel capacity.
Early detection of a performance drop makes the claim stronger and easier to prove.
How Long Does the Warranty Claim Process Take in Pakistan?
Timelines vary widely depending on the brand, distributor, and nature of the claim. Realistically:
- Initial response from installer/distributor: 3–10 business days
- Technical inspection: 1–4 weeks (longer in remote areas)
- Claim decision: 2–6 weeks after inspection
- Replacement delivery and installation: 2–8 weeks after approval
Total end-to-end time for a straightforward claim: 6–16 weeks. Complex or disputed claims can stretch to 6–12 months, especially if escalation to the consumer court is required.
Best Solar Panel Brands with Strong Warranty Support in Pakistan
Not all brands are equally responsive when warranty time comes. Based on general industry reputation and user experiences reported in Pakistan’s solar community, the following brands tend to have more reliable local warranty support:
Longi Solar (LONGi Green Energy)
One of the world’s largest panel manufacturers, with distribution partnerships across Pakistan. Known for honoring product and performance warranties through local distributors, though response times can vary by city.
JA Solar
A popular choice in Pakistan’s commercial and residential market. Their Pakistani distributors generally maintain adequate inventory for warranty replacements.
Canadian Solar
Strong brand recognition globally and in Pakistan. Their warranty documentation is clear, and their escalation channels are accessible.
Jinko Solar
Widely used in large-scale projects in Pakistan. Their warranty support quality depends significantly on which local distributor you purchased through.
Caution with budget brands: Many small Chinese brands sold in Pakistan’s local bazaar markets (Lahori Mandi, Shershah Karachi, Raja Bazaar Rawalpindi) offer little to no real warranty support.
If the company does not have a verified Pakistan office or AEDB registration, the warranty printed on the carton is largely unenforceable.
Frequently Asked Questions
Can I claim warranty if my panels were damaged by hail?
Generally no. Hail damage is considered an “act of nature” and falls under home or commercial property insurance, not the panel manufacturer’s warranty. Check whether your home insurance policy covers installed solar equipment.
What if the company that installed my panels has shut down?
This is unfortunately common in Pakistan’s rapidly growing but volatile solar market. Your options are:
- Contact the panel manufacturer or their authorized distributor directly
- File a complaint with AEDB if the installer was registered
- Pursue through the consumer court with the purchase documentation
My panels are producing less than expected, but there’s no visible damage. Is this a warranty issue?
It could be. First rule out other causes: inverter faults, shading, wiring issues, soiling (dust on panels). If all those are eliminated and your monitoring data shows degradation beyond the warranted rate, it is a valid performance warranty claim.
Do I need a lawyer to file a solar warranty claim in Pakistan?
Not for the initial claim process. However, if you proceed to the consumer court, consulting a local consumer lawyer is advisable. Many consumer lawyers in Pakistan work on a contingency basis for clear-cut cases.
Is my warranty void if I add more panels to the system later?
Not necessarily — but the warranty for the original panels remains separate from the newly added panels. Ensure a certified installer does any expansion to protect both warranties.
