Introduction
JA Solar is one of the earliest and most widely distributed solar panel brands in the Vietnamese market. Positioned in the mainstream TOPCon segment, the DeepBlue 4.0 Pro lineup strikes a balance between stable efficiency, low degradation, and competitive pricing, a safe, reliable choice for the majority of residential and commercial projects.
History & Scale
Founded in 2005 and headquartered in Beijing, JA Solar has been listed on the Shenzhen Stock Exchange (SZSE) under ticker 002459 since 2019. The company holds Bloomberg Tier 1 status and ranks among the world’s highest-volume solar manufacturers. Its broad distribution network across Vietnam ensures reliable supply and long-term warranty support.
Core Technology
The flagship DeepBlue 4.0 Pro series uses n-type TOPCon cells with the company’s proprietary cell technology branded Bycium+, featuring a dual-glass bifacial design that generates power from both sides. TOPCon delivers higher efficiency than the previous PERC generation, with a Pmax temperature coefficient of −0.29%/°C and an annual degradation rate of approximately 0.40%, consistent with the mainstream TOPCon tier as a whole.
Product Lineup
The representative 72-cell format model is the JAM72D40-595/MB (verified against the manufacturer’s datasheet); see the specification table above. Beyond the 72-cell format, JA Solar also offers larger formats such as the JAM72D42-LB 640W (compared in depth in KB 02-03). Multiple power output codes exist under the same DeepBlue name; always confirm the exact model code when designing a string layout.
Positioning in Vietnam
JA Solar is well suited to the majority of residential and commercial rooftop projects that require a reputable brand, abundant supply, and strong value for money. It is the “safe choice” when customers have no special requirements for maximum efficiency (back-contact technology) or high per-panel wattage (132-cell format).
Sales note
When comparing JA against AIKO or LONGi, emphasize the price-to-performance balance. When a customer asks about the JAM72D42-LB 640W (the larger format), refer additionally to the KB 02-03 comparison table to explain differences in efficiency and operating current. Always confirm the exact model code against the quoted wattage, as the DeepBlue lineup spans multiple Pmax ranges.
