1. Solar Panel Warranty Kya Hoti Hai?
Simple shabdon me, solar panel warranty manufacturer ki taraf se ek guarantee hoti hai ki panel ek certain time period tak:
- sahi se kaam karega
- expected power generate karega
- manufacturing defect se free hoga
India me normally 25 years ki performance warranty aur 10–12 years ki product warranty milti hai.
Yeh warranty batati hai ki panel time ke saath-kuch degrade toh hoga, par acceptable limit ke andar.
2. Solar Panel Warranty Ke Do Major Types
A) Product Warranty (10–15 years)
Product warranty protect karti hai:
- manufacturing defect
- glass breakage (limited cases)
- junction box failure
- panel ke internal crack
- wiring ya soldering defects
- PID (Potential Induced Degradation) issues
Iska time period India me:
- Normal Poly Panels: 5–10 years
- Mono PERC Panels: 10–12 years
- TOPCon Panels: 12–15 years
B) Performance Warranty (25–30 years)
Performance warranty power guarantee hoti hai.
Company guarantee deti hai ki panel:
- 1st year me 97–98% efficiency
- 25th year me 80–84% efficiency se kam nahi hoga
Performance warranty degradation pattern:
| Year | Expected Output |
|---|---|
| 1st Year | 97% |
| 2–10 Years | 0.55% annual loss |
| 11–25 Years | 0.45% annual loss |
| Final Output | 80–84% approx |
Yeh warranty ensure karti hai ki aapko long-term stable electricity mile.
3. Solar Panel Warranty Me Kya Cover Hota Hai?
✔ Manufacturing defect
✔ Broken cells (non-accident cases)
✔ PID effect
✔ Hot spot issues
✔ Less power generation
✔ Early degradation
✔ Junction box fault
✔ Back-sheet cracking
✔ Frame corrosion (non-coastal areas)
4. Solar Panel Warranty Me Kya Cover Nahi Hota?
✘ Accident / fire damage
✘ Flood, storm, hailstone damage
✘ Customer side rough handling
✘ Installation fault (installer ka mistake)
✘ Unauthorized repair
✘ Monkey damage, bird droppings
✘ Direct lightning strike
Matlab warranty only manufacturing-related problems ko cover karti hai, natural calamity ya mishandling ko nahi.
5. Performance Warranty vs Product Warranty Difference
| Feature | Product Warranty | Performance Warranty |
|---|---|---|
| Time Period | 10–15 years | 25–30 years |
| Covers | Hardware issues | Power output loss |
| Example | Junction box fail | 25 saal ke baad 80% output |
| Claim Process | Fast | Slow, testing required |
6. Solar Inverter Warranty vs Solar Panel Warranty
Many people confuse both.
| Component | Warranty |
|---|---|
| Solar Panel | 25 years (performance) |
| Solar Inverter | 5–10 years |
| Battery (Lithium) | 5–8 years |
| Balance of System | 1–3 years |
Panels longest warranty dete hain.

Step 1: Proof of purchase sambhal kar rakhe
- Invoice
- Warranty card
- Installation pictures
Step 2: Installer firm ko contact karein
Woh manufacturer ko forward karte hain.
Step 3: Manufacturer testing karta hai
- Panel testing
