Module JA SOLAR JAM54D41-445/LB – Full black – Bifacial

JA SOLAR n-type Bifacial Double Glass Photovoltaic Panel JAM54D41 LB

The JA SOLAR photovoltaic panel from the DEEP BLUE 4.0 Pro series, model JAM54D41 LB, is an advanced, bifacial monocrystalline n-type module built with double glass (glass-glass) technology. It delivers higher power generation and a better levelized cost of energy (LCOE) thanks to very low degradation, an excellent temperature coefficient, and strong low-light performance. This is a premium solution that combines high efficiency, reliability, and exceptional durability.

Key features of the JA SOLAR JAM54D41 LB Photovoltaic Panel:

• n-type Bifacial Double Glass technology: The glass-glass bifacial design combined with n-type cells provides additional energy yield from the rear side of the module (bifaciality 80%±10%), very low light-induced degradation (LID), and increased durability.
• Long-term performance warranty: 25-year product warranty and a 30-year linear power warranty, ensuring 87.4% of rated power after 30 years (degradation in the first year ≤1%, in subsequent years ≤0.4%).
• High power and efficiency: Rated power ranging from 430 W to 455 W and module efficiency up to 22.8%, maximizing energy production per unit of area.
• Excellent performance in challenging conditions: A superior temperature coefficient (−0.300%/°C) and improved low-light response ensure higher energy yield under real-world operating conditions.
• Enhanced mechanical robustness: The double tempered glass construction (1.6 mm + 1.6 mm) provides high resistance to static loads (up to 5,400 Pa front and 2,400 Pa rear).

Who is this a good choice for?

The JA SOLAR JAM54D41 LB module is an excellent choice for investors and system owners seeking a premium product with maximum performance and long-term reliability. Its bifacial design makes it ideal for ground-mounted systems or flat roof installations where reflected light can be utilized to increase energy yield. Its high durability and environmental resistance make it a secure investment for commercial projects and demanding residential installations aiming to achieve the lowest possible levelized cost of energy (LCOE).
