Jinko Solar Tiger Neo and JA Solar DeepBlue 4.0 are the two most popular N-type TOPCon solar panels in Bangladesh. This head-to-head comparison covers efficiency, warranty, temperature performance, price, and which is better for Bangladesh's climate.
The transition from P-type PERC to N-type TOPCon solar panels is well underway in Bangladesh. The two dominant brands in the Bangladeshi market — Jinko Solar Tiger Neo and JA Solar DeepBlue 4.0 — both use N-type TOPCon cell technology, offering higher efficiency, better low-light performance, and lower temperature coefficients than the PERC panels that dominated the market until 2023. But which one is right for your project?
| Parameter | Jinko Tiger Neo N-Type | JA Solar DeepBlue 4.0 |
|---|---|---|
| Cell technology | N-type TOPCon | N-type TOPCon |
| Peak power (600W variant) | 605 Wp | 610 Wp |
| Module efficiency | 22.27% | 22.4% |
| Temperature coefficient (Pmax) | -0.29%/°C | -0.30%/°C |
| Product warranty | 12 years | 12 years |
| Performance warranty (year 25) | 87.4% (linear) | 87.4% (linear) |
| Annual degradation | 0.4% | 0.4% |
| Bifacial gain (typical) | 10–25% | 10–25% |
| IEC certification | IEC 61215, IEC 61730 | IEC 61215, IEC 61730 |
| Price in Bangladesh (approx.) | BDT 28–32/Wp | BDT 27–31/Wp |
Bangladesh's climate presents specific challenges for solar panels: high ambient temperatures (35–42°C in summer), high humidity (80–95% relative humidity), and frequent dust and pollution in industrial areas. Both Jinko Tiger Neo and JA DeepBlue 4.0 perform well in these conditions, with their low temperature coefficients (-0.29 to -0.30%/°C) meaning less power loss on hot days compared to older PERC panels (-0.35%/°C).
For most industrial rooftop projects in Bangladesh, both panels are excellent choices and the difference in real-world performance is minimal (less than 1%). The decision often comes down to: current stock availability in Bangladesh, price at the time of procurement, and your EPC contractor's authorized partnership status. Vvon Technologies is an authorized partner of both Jinko Solar and JA Solar, and we recommend based on current pricing and project-specific requirements. Explore our solar panel range →
