Solar Panel Technology — Teen Main Types
2025 mein India mein teen main technologies available hain. Har ek ke pros aur cons samajhna zaroori hai apke budget aur roof ke hisaab se sahi choice karne ke liye.
1. Mono PERC — Most Popular Choice
PERC = Passivated Emitter and Rear Cell
Mono PERC panels abhi India mein sabse zyada install hote hain. Reason:
- Efficiency: 19–21%
- Price: ₹22–28 per watt
- Performance in heat: Moderate (temperature coefficient ~-0.35%/°C)
- Low light performance: Good
- Warranty: 25 year linear output warranty (standard)
Rajasthan ke liye: Theek hai lekin extreme heat (45°C+) mein performance thodi drop hoti hai.
Best brands: Adani Solar, Waaree, Vikram Solar, Tata Power Solar
2. TOPCon — New Generation Technology
TOPCon = Tunnel Oxide Passivated Contact
TOPCon 2024-25 mein rapidly popular ho raha hai. Price Mono PERC se thoda zyada lekin performance significantly better:
- Efficiency: 21–23%
- Price: ₹28–35 per watt
- Temperature coefficient: -0.28%/°C (better than Mono PERC)
- Bifacial variant available (rear side se bhi light absorb karta hai)
- Warranty: 30 year output warranty (most brands)
Rajasthan ke liye: Excellent choice. Heat mein Mono PERC se 8–12% better output. Desert conditions ke liye ideal.
Best brands: Adani Solar (Adani TOPCon), Waaree (HiKu7), REC Group
3. HJT — Premium Tier
HJT = Heterojunction Technology
HJT sabse premium technology hai — highest efficiency aur best temperature performance:
- Efficiency: 22–24%
- Price: ₹40–50 per watt
- Temperature coefficient: -0.24%/°C (best among all)
- Bifacial: Almost always bifacial
- Warranty: 30 year output warranty
Rajasthan ke liye: Rajasthan ki extreme heat mein HJT sabse best perform karta hai. Lekin cost 40–50% higher hai Mono PERC se. Recommend karte hain jab roof space limited ho ya commercial high-load installation ho.
Best brands: REC Alpha, Panasonic EverVolt, Canadian Solar HiHero
