JA Solar DeepBlue 4.0 JAM54D40 (435–460W)

Advanced N-Type TOPCon Cell Technology:
The module uses N-type TOPCon cell architecture, improving carrier transport and reducing recombination losses to deliver higher energy yield and lower degradation compared with conventional P-type modules.

High Power Output (435–460W):
Designed for residential and light commercial rooftop systems, the module offers 435W to 460W power output with module efficiency reaching up to ~23%, helping maximise energy production from limited roof space.

Excellent Temperature Performance (~-0.29%/°C):
A temperature coefficient of approximately -0.29%/°C helps maintain stable generation even in high operating temperatures, supporting reliable performance in hot climate conditions.

Enhanced Low-Light Performance:
Optimised N-type cell design and advanced multi-busbar technology improve power generation during cloudy weather, early mornings, and late afternoons.

Lower Degradation Rate:
The module experiences ≤1% first-year degradation and around 0.4% annual degradation, supporting higher long-term energy yield over the system’s lifetime.

Strong Mechanical Durability:
Built with durable double-glass construction and a reinforced frame, the module is certified for wind loads up to 2400Pa and snow loads up to 5400Pa, ensuring reliability in demanding environments.

1500V System Compatibility:
The module supports modern 1500V DC system designs, allowing more efficient system configuration and reduced balance-of-system costs in larger installations.

Long-Term Warranty Protection:
Backed by a 12-year product warranty and 30-year linear performance warranty, ensuring reliable performance and long-term system confidence.
