JASolar JASOL JAM54D41-440/MB 440W N-Type Bifacial Solar Panel (108 Half-Cell) – Black Module
The JASOL JAM54D41-440/MB 440W is a modern, high-output N-type bifacial solar panel designed to deliver strong energy production for residential rooftops, commercial arrays, and ground-mount solar projects. Built with an advanced 108 half-cell (HC) layout, this module is engineered to reduce power loss, improve efficiency, and maintain stable performance in real-world conditions such as heat, partial shading, and changing sunlight.
What makes this panel stand out is its N-type cell technology and bifacial design. N-type modules are widely chosen for their strong long-term performance characteristics, while bifacial panels can generate additional energy from the rear side by capturing reflected light (albedo) from surfaces like light-colored roofs, concrete, gravel, or ground-mount installations. That means the JAM54D41-440/MB can be an excellent choice when you want maximum yield per panel, especially in installations where rear-side gain is possible.
With a 440W power rating, this module helps you reach your target system size with fewer panels—ideal for projects where space is limited or where reducing balance-of-system components (rails, clamps, wiring) matters. The black (BLK) appearance provides a clean, premium look for rooftop installations while still delivering the benefits of bifacial technology in the right conditions.

What Is the JAM54D41-440/MB?
The JASOL JAM54D41-440/MB is a bifacial photovoltaic (PV) module that converts sunlight into DC electricity for use with solar inverters and optional battery storage. Unlike standard monofacial panels that collect light mainly on the front, bifacial panels can produce power from both the front and rear—potentially increasing total system output when installed over reflective surfaces and with proper mounting clearance.
In short: it’s a high-output 440W N-type bifacial solar panel built for customers who want higher potential energy yield and a premium black finish.
Who Is This Solar Panel For?
Homeowners Who Want More Power Per Panel
If roof space is limited and you want strong output with modern technology, a 440W module can reduce the total number of panels needed for your target system size.
Ground-Mount and Carport Solar Projects
Bifacial panels shine in ground-mount, pergola, and canopy/carport designs where the rear side can capture reflected light for added production.
Commercial and Industrial Solar Installations
For businesses aiming to reduce energy costs, bifacial N-type modules can improve system economics by increasing yield—especially in optimized mounting setups.
Solar Installers and EPCs
A great option for installers building premium systems where performance, long-term reliability, and customer value matter.
Hybrid Solar + Battery Systems
Compatible with grid-tied and hybrid designs where higher production improves battery charging and self-consumption—just ensure inverter and string sizing match the panel specifications.
Common Applications
-
Residential rooftop solar arrays (especially where reflective surfaces are present)
-
Ground-mounted solar systems
-
Solar carports and canopies
-
Commercial rooftop and industrial PV arrays
-
Hybrid solar + battery storage setups
Frequently Asked Questions (FAQ)
1) What does “N-type” mean and why does it matter?
N-type refers to a solar cell base material that is often chosen for strong efficiency and long-term performance characteristics. Many buyers prefer N-type modules when they want premium technology and reliable output over time.
2) What is a bifacial solar panel?
A bifacial panel can generate electricity from both the front and the rear side. The rear side captures reflected sunlight (albedo) from the ground or nearby surfaces, which can increase total energy production depending on installation conditions.
3) Will I always get extra power from bifacial panels?
Not always. Rear-side gain depends on factors like mounting height, tilt, spacing, and the reflectivity of the surface below (light roofs, concrete, gravel typically help). Ground-mount and canopy installs tend to benefit the most.
4) What does “108 half-cell (HC)” mean?
Half-cell designs reduce internal resistance and power loss. They can also help the panel maintain better output under partial shading compared to older full-cell designs.
5) Is this panel suitable for rooftop residential solar?
Yes. It’s a strong choice for residential rooftop systems—especially if you want higher wattage per panel and a clean black appearance. Your installer should confirm layout and inverter/string sizing for your specific system.
