JA Solar Deep Blue 4.0 Pro 455W N-Type Bifacial Double-Glass Solar Panel JAM54D41

JA Solar DEEP BLUE 4.0 Pro JAM54D41 LB Photovoltaic Modules (455W)

The JA Solar DEEP BLUE 4.0 Pro JAM54D41 LB photovoltaic module is a high-performance, bifacial (double-sided) n-type module built with durable double-glass technology.
We only supply the 455W model, which offers excellent operating parameters, including a low temperature coefficient and extremely low light-induced degradation (LID). This ensures high energy generation, reduced levelized cost of energy (LCOE), and long-term reliability supported by extended warranties.

Key Features of the 455W JA Solar DEEP BLUE 4.0 Pro JAM54D41 LB Module

• High Power and Efficiency:
  Rated output of 455W, with module efficiency up to 22.8%, delivering maximum energy production from the same installation area.

• n-type Bifacial Double-Glass Technology:
  Double-sided energy generation with bifaciality of 80% ±10%, plus enhanced durability and resistance to harsh environmental conditions thanks to the double-glass structure.

• Low Degradation & Excellent Temperature Performance:
  Extremely low LID; first-year degradation ≤1%, and annual degradation ≤0.4% thereafter.
  Favourable Pmax temperature coefficient of -0.300%/°C ensures better performance on hot days.

• Extended Warranties:
  25-year product warranty + 30-year linear output warranty (maintaining 87.4% power after 30 years).

• Superior Low-Light Response:
  Designed to perform better under low-light conditions, increasing total daily and annual energy yield.

• Comprehensive Certifications:
  IEC 61215, IEC 61730, ISO 9001, ISO 14001, ISO 45001, IEC 62941.
