Solar technology pichhle do saalon mein bahut tezi se evolve hui hai. Jahan kuch saal pehle tak Mono PERC panels sabse modern maane jaate the, wahi 2026 mein N-Type TOPCon technology nayi benchmark ban chuki hai.
Agar aap naya solar power plant lagwane ja rahe hain, toh in dono technologies ke beech ka farq samajhna zaroori hai, khaaskar Rajasthan jaise high-temperature ilakon ke liye.
Mono PERC Panels Kya Hain?
Mono PERC (Passivated Emitter and Rear Cell) P-type silicon technology par aadharit hoti hai. Yeh standard monocrystalline panels hote hain jinki efficiency lagbhag 20% se 21.5% ke beech hoti hai.
N-Type TOPCon Technology Kya Hai?
TOPCon (Tunnel Oxide Passivated Contact) N-type silicon wafer ka upyog karti hai. Isme ek ultra-thin tunnel oxide layer hoti hai jo electron recombination ko kam karti hai.
Is technology ki module efficiency 22.5% se 24.5% tak pahunch jati hai, aur low light (subah, shaam aur cloudy weather) mein bhi behtar power generation milti hai.
Rajasthan Ki Garmi Mein Kaun Sa Behtar Kaam Karta Hai?
Jaise jaise dhoop mein panel ka temperature 25°C se upar jata hai, waise waise solar panels ki power thodi drop hoti hai. Ise Temperature Coefficient kehte hain:
- Mono PERC: -0.35% per °C drop
- N-Type TOPCon: -0.30% per °C drop
Garmi ke dino mein (40°C–45°C ambient temperature), TOPCon panels Mono PERC ke mukable lagbhag 4% se 6% zyada units generate karte hain.
Technical Specs Comparison
| Specification | N-Type TOPCon | Mono PERC |
|---|---|---|
| Module Efficiency | 22.5% – 24.5% | 20.0% – 21.5% |
| First Year Degradation | ≤ 1.0% | ≤ 2.0% |
| Annual Degradation | 0.40% / year | 0.55% / year |
| Performance Warranty | 30 Years | 25 Years |
| Price Difference | ~ ₹1.00 – ₹1.50 / W more | Standard Price |
Conclusion
Dono technologies ke daam mein ab bahut kam antar bacha hai, jabki TOPCon panels 30 saal tak chalte hain aur garmiyon mein zyada power dete hain. Agar aap 2026 mein naya system laga rahe hain, toh DCR N-Type TOPCon Bi-facial panels lagwana long-term ke liye sabse samajhdari bhara faisla hai.
Frequently Asked Questions
Kya TOPCon panels par PM Surya Ghar subsidy milti hai?
Haan, jab tak TOPCon module DCR (Domestic Content Requirement) certified hai, us par poori ₹78,000 tak ki subsidy milti hai.
Bifacial TOPCon panel ka kya fayda hota hai?
Bifacial panel aage ke sath-sath peechhe se reflected light (albedo) se bhi 10% se 25% tak extra power banata hai.
