Let’s be honest. When most of us invest in solar panels, we focus on the savings. That juicy monthly drop in electricity bills? Yes, please. But here’s what I learned after doing a deep dive into the solar world: understanding solar panel warranties is just as important as the panels themselves.
I’d argue it’s more important in the long run. Why? Because your warranty is the safety net that protects your solar investment for years to come. And in Pakistan—where the market is growing fast and not all vendors play fair—understanding what your warranty really covers can save you a lot of frustration (and money).
So let’s break it down in plain English. What should every homeowner in Pakistan know about solar panel warranties?
The 3 Types of Solar Panel Warranties You Must Know
Buying a solar system without checking the warranty is like buying a car with no insurance. Three primary warranty types are included with every reliable panel:
1. Product Warranty (Equipment Warranty)
This one is simple: it covers the physical quality of your panels. If your panel stops working due to a manufacturing defect, the company will replace or repair it at no additional cost.
- Typical Coverage: 10 to 12 years
- What’s Covered: Broken glass (not due to accidents), loose connections, internal faults
- Pro Tip: Always choose Tier-1 brands like JA Solar, Jinko, Longi, or Canadian Solar—they offer stronger warranties
2. Performance Warranty
Now here’s where it gets interesting. All solar panels degrade over time. But how fast?
A performance warranty guarantees that your panel will still generate a certain percentage of power even after 25 years.
- Typical Coverage: 25 years
- Guaranteed Output: Usually around 80–85% by year 25
- Why It Matters: You’re not just buying a panel for today—you’re buying long-term performance.
3. Installation Warranty (Service Warranty)
This depends on your installer. It covers problems due to poor installation—loose wiring, improper mounting, leaks, etc.
- Typical Coverage: 1 to 5 years
- What You Should Ask: “Will you provide after-sales service for system failures, and how quickly?”
Solar Panel Warranties in Pakistan: What’s the Ground Reality?
Let’s talk facts.
In Pakistan, most solar dealers offer warranties, but very few honor them properly. Some make big promises but disappear when problems arise. That’s why you must always:
- Choose licensed vendors (like JS Technology—we’ve got your back)
- Make sure warranty certificates are in writing
- Confirm if your vendor provides local service or sends it abroad for replacement (spoiler: that could take months)
Real Example: What a Strong Warranty Looks Like
Let’s say you install a 10kW system using Longi solar panels. Here’s what your warranty package could look like:
- Product Warranty: 12 years
- Performance Warranty: 25 years (with 84.8% output guaranteed)
- Inverter Warranty: 5–10 years (depending on brand)
- Installation Warranty: 3 years (if done by a certified installer)
So even if one panel underperforms in year 10, you can claim a free replacement, subject to warranty terms. That’s peace of mind.
How to Verify If a Solar Panel Warranty Is Legit
Here’s a mini checklist I use when evaluating any solar offer:
Is the warranty provided in writing?
Is the warranty backed by the manufacturer or just the local dealer?
Are there any hidden costs for service, transport, or inspection?
Will someone be available in your city if something goes wrong?
Does the warranty include the inverter and batteries?
If the answer is “no” to any of the above, reconsider your choice.
What About Warranties for Batteries and Inverters?
Good question. We often forget that your solar storage system also needs coverage.
- Batteries (Lithium-Ion): Usually come with a 5 to 10-year warranty based on cycles.
- Inverters: Branded ones like Growatt, Fronius, or Huawei offer 5 to 10 years.
Again, the key is proper documentation, understanding solar panel warranties, and trusted dealers. (You can also check out our blog on How Solar Energy Can Lower Your Electricity Bills to learn how these systems impact your monthly savings.)
Let’s Bust a Few Myths
There are a lot of misconceptions floating around. Let’s clear the air.
❌ “If one panel fails, my whole system stops working.”
✅ Not true. Panels are connected in strings. One underperforming panel won’t crash the system.
❌ “Warranties only work outside Pakistan.”
✅ Not if you buy from certified local partners of global manufacturers.
❌ “The dealer handles everything.”
✅ Only if they’re authorized and committed. Always ask about after-sales support.
A Warranty Isn’t Just a Paper—It’s Your Power Promise
Let me be straight with you—solar is a fantastic investment. But like any investment, it needs protection. understanding solar panel warranties is your guarantee that your system will work the way it’s supposed to for decades.
In Pakistan’s fast-evolving solar market, being an informed homeowner gives you the upper hand. Don’t settle for verbal promises. Get everything in writing, ask the right questions, and make sure your installer doesn’t vanish after the payment clears.
And if you’re overwhelmed or unsure, just reach out. At JS Technology, we help homeowners understand every clause, every condition, and every promise—so you’re never left in the dark.
