Thinking of switching to solar power but wondering how long your system will last? Understanding the lifespan of solar panels and inverters—especially in Indian weather—is essential for making the most of your investment.
Quick Answer:
- Solar Panels Last: 25–30 years (with 80%+ efficiency)
- Solar Inverters Last: 8–12 years (replaceable & upgradable)
Lifespan of Solar Panels in India
Most Tier-1 rooftop solar panels in India come with a 25-year performance warranty. After that, they may still work efficiently at around 80–85% of their original output.

Key Factors Affecting Solar Panel Life in India:
- Heat & UV Radiation: Solar panels are designed to handle extreme Indian summers, but mild degradation may occur over decades.
- Pollution & Dust: In cities like Delhi, Ahmedabad, and Mumbai, heavy dust and pollution can reduce efficiency without frequent cleaning.
- Monsoons & Coastal Humidity: Waterproof installations are crucial in regions like Kerala, Chennai, and Goa.
Tips to Extend Lifespan:
- Use Tier-1, BIS/IEC certified panels
- Install with corrosion-resistant structures
- Regular panel cleaning and health checks
Lifespan of Solar Inverters in India
Inverters have a shorter lifespan than panels due to heat and electrical load.
| Inverter Type | Expected Lifespan |
| String Inverter | 8–12 years |
| Microinverter | 15–20 years |
| Hybrid Inverter | 10–15 years |
