JA SOLAR DEEP BLUE 4.0 Pro

The JA SOLAR DEEP BLUE 4.0 Pro modules are a series of high-performance n-type Bifacial Double Glass photovoltaic panels designed to maximize energy production and reduce LCOE (Levelized Cost of Energy). They use n-type technology with very low light-induced degradation (LID), offer an improved temperature coefficient, and perform well in low-irradiance conditions.

Key features of the JA SOLAR DEEP BLUE 4.0 Pro:

• n-type technology with very low LID for longer-term, more stable performance.
• Bifacial Double Glass construction increases energy capture.
• Power output range of 430–455 W, with module efficiencies up to 22.8%.
• 25-year product warranty and a 30-year linear power output warranty.
• Improved temperature coefficient (-0.300%/°C for Pmax) and better response in low-light conditions.
• Certifications such as IEC 61215 and IEC 61730, and management systems including ISO 9001 (quality), ISO 14001 (environment), and ISO 45001 (occupational health and safety).

Who is this a good choice for?

The DEEP BLUE 4.0 Pro modules are ideal for photovoltaic installations where maximizing energy yield and long-term reliability are priorities, including ground-mounted, commercial, and rooftop systems. They are well suited to projects that demand high efficiency, resilience to changing weather conditions, and long-term warranties—resulting in lower energy costs over the lifetime of the installation.
