1. N-type TOPCon Modules (Deep Blue 4.0 Pro Series) This is JA Solar's current flagship high-efficiency product series, employing advanced
2. P-type PERC Modules
This is a widely used and mature product series from JA Solar, employing high-efficiency PERC (Emitter and Back Field Passivation) technology.
Features:
High Cost-Effectiveness: Relatively low cost, high cost-effectiveness.
Mature and Reliable: Widely used in the market, mature technology, with comprehensive product certifications.
Superior Performance: Combines multi-busbar (MBB) and half-cell technologies, effectively reducing shading losses and hot spot risk.
3. Bifacial Double-Glass Modules
This type of module, regardless of whether it uses P-type or N-type cell technology, has bifacial power generation capability.
Features:
Back Side Gain: Can absorb reflected and scattered light from the back side, increasing total power generation.
Strong Mechanical Load Capacity: Employs a double-glass structure, providing stronger weather resistance and mechanical compressive strength; for example, the front side can withstand 5400Pa of snow pressure, and the back side can withstand 2400Pa of wind pressure.
Longer Lifespan: The double-glass structure provides better moisture resistance and resistance to PID (Potential Induced Degradation). Core Common Technologies
Most of JA Solar's module products integrate the following technologies to optimize performance and reliability:
* Half-cell Technology: Cutting the cell in half reduces internal current and resistance losses, thereby increasing output power and reducing hot spot risk.
* Multi-Busbar (MBB) Technology: Using more busbars (typically 9BB, 11BB, or more) to collect current reduces current transmission distance, improving efficiency and reliability.
* Large-size Silicon Wafers: Employing large-size silicon wafers such as 182mm increases module power output.
