JA Solar DeepBlue 4.0 Bifacial Solar Panel – High-Efficiency N-Type Double-Glass Module
The JA Solar DeepBlue 4.0 is a premium n-type bifacial solar panel engineered to deliver exceptional efficiency, durability, and long-term energy production. Featuring advanced 16BB multi-busbar (MBB) half-cell technology and a robust double-glass bifacial design, this high-performance module achieves up to 26.0% efficiency while maximizing energy harvest in both direct sunlight and low-light conditions.
Designed with an elegant all-black finish, the DeepBlue 4.0 is an excellent choice for homeowners and businesses seeking a modern appearance without compromising performance. Its bifacial technology captures reflected sunlight from the rear side of the panel, increasing total energy yield and improving the return on investment for residential, commercial, and industrial solar installations.
Built using n-type solar cell technology, the DeepBlue 4.0 offers lower light-induced degradation (LID), superior temperature performance, and higher long-term power retention compared to conventional p-type modules. The durable double-glass construction provides enhanced protection against moisture, corrosion, snow, wind, and other harsh environmental conditions, ensuring reliable performance throughout its service life.
Backed by a 12-year product warranty and an industry-leading 30-year linear power output warranty, the JA Solar DeepBlue 4.0 delivers dependable clean energy for decades, making it one of the best choices for high-efficiency rooftop and ground-mounted solar systems.
