Switching to solar is a long-term investment — not just in technology, but in your home’s energy future. When you buy a solar panel, you expect it to perform for decades, reducing your electricity bills and saving the environment. But here’s a fact many homeowners overlook: the solar panel warranty period is just as important as the panel’s capacity or brand.
Why? Because a warranty protects you from unexpected repair or replacement costs. In India’s hot, dusty, and often unpredictable climate, your panels will be exposed to tough conditions — and your warranty is the safety net that keeps your savings plan intact.
In this article, we’ll break down solar warranties in simple terms so you can make a smarter buying decision and avoid costly surprises.
What is a Solar Panel Warranty?
Think of a solar panel warranty as a promise from the manufacturer. It says:
“We guarantee this panel will perform at a certain level for a specific time. If not, we’ll fix or replace it.”
Without a warranty, any fault — even one caused by manufacturing defects — becomes your financial burden. For an investment that lasts 20+ years, this protection is essential.
Types of Solar Warranties
There are two main types of warranties you’ll encounter when shopping for solar panels:
a. Product Warranty
- Covers physical defects in materials or workmanship.
- Protects you if your panel cracks, delaminates, or suffers damage from faulty manufacturing.
- Common in India: 10–12 years.
Example: If a panel stops working in year 7 because of a hidden manufacturing fault, a valid product warranty ensures you get a free replacement or repair.
b. Performance Warranty
- Guarantees your panels will still produce a certain percentage of their original capacity over time.
- Typically valid for 25 years, with most brands promising at least 80% output by the end of the term.
Example: A 400W panel with a 25-year performance warranty might guarantee at least 320W output after 25 years.
Typical Solar Panel Warranty Period in India
Warranty Type | Average Duration | Coverage Focus | |
Product Warranty | 10–12 years | Defects & manufacturing issues | |
Performance Warranty | 25 years | Output efficiency guarantee |
Pro Tip: A brand offering a 25-year performance warranty with only a 5-year product warranty is cutting corners. Aim for both warranties to be strong.
What’s Covered and What’s Not
Covered:
- Internal manufacturing defects
- Faulty solar cells
- Premature drop in power generation under normal weather conditions
Not Covered:
- Damage due to poor installation practices
- Fire, flood, or lightning strikes
- Dirt buildup or lack of maintenance
Always check if installation by unauthorized technicians voids the warranty — it often does.
Cost vs. Savings: Why Warranty Matters
Let’s say you spend ₹2.5 lakh on a solar system. Without a strong warranty, replacing even a single faulty panel in year 8 could cost you ₹10,000–₹15,000. Over two decades, such costs add up, reducing your return on investment.
With a 25-year performance warranty and a solid product warranty, you:
- Avoid unexpected replacement costs
- Maintain steady electricity savings
- Ensure your ROI stays intact
A warranty is not just “paperwork” — it’s a financial safeguard.

How to Choose Panels with the Best Warranty
- Read the fine print – Make sure “25 years” isn’t just for performance.
- Compare brands – Look for companies with a proven track record in India.
- Check service network – A warranty is useless if the company has no local support.
- Ask about labor coverage – Some warranties cover only the panel, not installation costs.
- Install with certified experts – Improper installation can void your warranty instantly.
FAQ – Solar Panel Warranty Period
- How long is the average solar panel warranty period in India?
- Product warranty: 10–12 years; Performance warranty: 25 years.
- If my panel underperforms, how do I claim warranty?
- Contact your installer or manufacturer with test reports and purchase details.
- Does warranty cover accidental damage?
- Usually no. Consider additional insurance for storm or fire protection.
- Will cleaning my panels myself void the warranty?
- No, as long as you follow recommended cleaning methods and don’t damage them.
