N-type vs P-type Solar Cell Comparison
N-type solar technology offers higher efficiency,lower degradation, and better long-term performance compared with conventional P-type modules.
| Comparison Item | N-type TOPCon | P-type PERC |
| Cell Efficiency | Higher conversion efficiency | Relatively lower efficiency |
| Power Output | Higher module wattage potential | Lower output under the same module size |
| Degradation | Lower first-year & annual degradation rate | Higher annual degradation over lifetime |
| Temperature Performance | Better low-temperature coefficient & hot climate adaptability | Inferior performance under high ambient temperature |
| Bifacial Gain | Excellent rear-side power generation gain | Limited bifacial power generation performance |
| Energy Yield | Higher lifetime energy yield | Lower long-term energy production |
| LCOE | More competitive long-term LCOE | High lifetime LCOE |
| Project Value | Ideal for utility-scale & C&I solar projects | Suitable for cost-sensitive conventional projects |

FAQ
What is the advantage of the 78-cell half-cut design?
The 78-cell half-cut design reduces internal resistance and hot spot risk. It also improves shade tolerance, maintaining higher power output when part of the panel is shaded.
How much extra energy can I get from its bifacial double-glass design?
You can expect 10-25% additional rear-side energy gain under typical conditions. With proper height and reflective surfaces (white gravel, concrete), this gain can reach up to 30%.
How does the 23.2% efficiency benefit my project?
What durability benefits does the double-glass construction provide?
Double-glass design offers better resistance to UV radiation, moisture and corrosion. It extends the panel's service life and supports the 30-year linear power warranty.
How does its -0.29%/°C temperature coefficient compare to standard panels?
It is significantly better than conventional P-type panels (-0.40%/°C). This means it loses 40% less power in hot weather, delivering superior performance in tropical and desert regions.
