Solar Panel Warranty in India — What's Really Covered
Updated March 2026 | Sri Ishaan Solar
Every solar company says "25-year warranty." But there are actually 3 different warranties and most people only know about one.
The 3 Types of Solar Warranty
1. Panel Performance Warranty (25 years)
The manufacturer guarantees the panel will produce at least 80% of rated power after 25 years. This is standard across all Tier-1 brands.
2. Panel Product Warranty (10-12 years)
Covers manufacturing defects — cracked cells, delamination, junction box failures. This is what actually matters in the first decade.
3. Workmanship Warranty (1-10 years, varies by installer)
Covers the installation quality — mounting structure, wiring, waterproofing, cable management. This is where most problems occur.
What to Ask Your Installer
- How many years workmanship warranty? (minimum 5)
- Does it cover roof leaks from mounting?
- Who do I call for service — you or the manufacturer?
- Is there an annual maintenance plan?

Hail damage (గడ్డ వర్షం) warranty లో వస్తుందా?
Standard warranty covers manufacturing defects only — hail, storm, falling objects (acts of God) కవర్ అవ్వవు. Panel insurance (All Risk policy) add-on తీసుకోండి — ₹2,000–₹3,000/year for 5 kW system. Sri Ishaan Solar insurance tie-up available. Telangana hail incidents rare (April–May) but insurance wise investment.
10 సంవత్సరాల తర్వాత installer company ఉండకపోతే warranty ఎలా claim చేయాలి?
Warranty is with manufacturer (Waaree/Adani), not installer. Manufacturer directly contact చేయవచ్చు — serial number + purchase invoice తో. Sri Ishaan Solar 2017 నుండి active — long-term service available. Manufacturer service centers pan-India ఉంటాయి.
