Key Advantages (N-Type + Thin-Frame)
N-Type Technology: Higher Efficiency & Lower Degradation
Technical Principle: Compared with PERC (P-type), N-type cells use phosphorus doping, which reduces Light-Induced Degradation (LID) and Potential-Induced Degradation (PID). First-year degradation ≤2% (vs. 3–4% for PERC); 25-year power retention ≥85% (vs. 80% for PERC).
For a 1MW commercial project, this means an extra 5,000+ kWh annual electricity output and 125,000+ kWh more over 25 years—directly boosting ROI.
Thin-Frame Design: Easy Installation & Space Saving
Frame thickness reduced to 30mm standard frames: 38-45mm); weight 18.5kg (5% lighter than standard 210W modules)，Fits narrow rooftop gaps (e.g., between HVAC equipment) and reduces labor time by 15% (fewer brackets needed)
For urban commercial buildings with limited rooftop space, 100 modules save ~15㎡ of installation area vs. standard-frame models—enough to add 2 extra modules (420W) for higher total power.
Warranty: 5-year product warranty (covers frame deformation, cell cracking, and material defects) + 25-year linear performance warranty (power retention ≥85% after 25 years).
Case Reference: “Used in 50,000㎡ commercial rooftop project in Shanghai (2023)—12 months of operation show 23.8% actual efficiency, 0.8% degradation (well below the 2% first-year limit).”
N-Type vs PERC PV Module: What’s the Difference?
| Comparison Dimension | KINGSUN 210W N-Type Thin-Frame | Standard 210W PERC Module |
|---|
| Conversion Efficiency | 23-24% | 21-22% |
| First-Year Degradation | ≤2% | 3-4% |
| 25-Year Power Retention | ≥85% | ≥80% |
| Weak-Light Performance | 10-12% higher (dawn/dusk) | Baseline |
| Frame Thickness | 30mm (thin) | 38-45mm (standard) |
Frequently Asked Questions (FAQs)
Q1: Can the 210W N-type thin-frame module be used for ground-mounted projects?
A1: Yes—its 5400Pa mechanical load resistance meets ground project requirements. However, it’s more cost-effective for rooftop scenarios (where space is scarce) to maximize the thin-frame advantage.
Q2: How does the thin frame affect durability?
A2: The frame uses high-strength 6063-T5 aluminum alloy (same as standard frames) with anodic oxidation treatment—thickness reduction doesn’t compromise load capacity (5400Pa positive load) or corrosion resistance.
