Why TOPCon and PERC Panels Are the Best Choices: Know the Facts Before Investment
As the world moves toward sustainable energy, Selecting the best solar panel technology is essential for long-term performance and cost-effectiveness. Among the latest advancements, PERC (Passivated Emitter and Rear Cell) and TOPCon (Tunnel Oxide Passivated Contact) solar panels are the most dependable and effective solutions.
At Sunbond Solar Energy Pvt. Ltd., We specialize in offering state-of-the-art solar technology that guarantees optimal power output, longevity, and return on investment. Let’s examine why TOPCon and PERC are the greatest options for your solar energy requirements before you invest.
What Is TOPCon Solar Panel Technology?
Tunnel Oxide Passivated Contact, or TOPCon, is a cutting-edge solar cell technology that increases light absorption and reduces electron loss to increase energy efficiency. To enhance power conversion, it makes use of highly conductive polysilicon contacts and a thin tunnel oxide layer.
Key Features of TOPCon Solar Panels
- Rear Passivation Layer: improves light absorption for increased efficiency.
- Greater Power Output: Among the greatest standard technologies, it offers 20–22% efficiency.
- Affordable and Reliable: provides an excellent balance between price and performance.
- Better Temperature Performance: work efficiency in hot climates.
What Is PERC Solar Panel Technology?
By including a rear passivation layer that reflects unabsorbed sunlight into the cell, PERC (Passivated Emitter and Rear Cell) technology enhances conventional solar cells. As a result, the panel may produce more electricity while receiving the same amount of sunshine.
Key Features of TOPCon Solar Panels
- Rear Passivation Layer: improves light absorption for increased efficiency.
- Greater Power Output: Among the greatest standard technologies, it offers 20–22% efficiency.
- Affordable and Reliable: provides an excellent balance between price and performance.
- Better Temperature Performance: work efficiency in hot climates.
How Do TOPCon and PERC Technologies Work?
| Feature | TOPCon Solar Panels | PERC Solar Panels |
|---|---|---|
| Silicon Type | N-type Silicon | P-type and N-type Silicon |
| Efficiency | 24-28% | 20-22% |
| Electron Flow | Uses a tunnel oxide layer to reduce recombination loss | passivation layer to increase reflectio |
| Performance In Low Light | High | Moderate |
| Temprature Resistance | Better (low-temperature coefficient) | Good |
| Lifespan | Longer (low degradation rate) | Standard |
| Cost | Slightly higher but better ROI | More affordable upfront |
TOPCon vs PERC A Detailed Comparison
Performance & Efficiency
- TOPCon panels: can achieve 24-28% efficiency, outperforming PERC panels.
- Most customers find PERC panels to be cost-effective because of their acceptable 20–22% efficiency.
Cost & Affordability
