JA Solar 450W Solar Panel JAM54D41-LB Bifacial Full Black - 31-120184

The JA Solar 450W solar panel is a high-performance photovoltaic module designed to offer superior energy production and long-lasting reliability.
It combines advanced manufacturing technologies with modern and elegant aesthetics, making it a versatile and efficient solution for a wide variety of photovoltaic systems.

This board belongs to the Deep Blue 4.0 Pro series, a range designed for those looking for a premium module with high durability, with an extra output thanks to the double glass bifacial technology.
It is a very interesting option for demanding residential self-consumption as well as for commercial installations where you want to maximise the yield per square metre without sacrificing a neat image.

This model uses n-type technology and a half-cell design with 108 cells (6×18), which helps to improve panel behaviour in partial shadows and reduces internal losses.
Under conditions with an additional 10% of rear irradiance, this module can increase its effective power output significantly.

With a nominal power of 450 W and an efficiency of 22.5 %, this solar panel maximises energy production per square metre, reducing the number of modules required and optimising the space available on the roof.

Main features of the JA Solar 450W Solar Panel

Advanced technology

This solar panel uses N-type monocrystalline solar cells with bifacial technology, which allows energy to be captured from both the front and the back.

Its technology provides important advantages such as:

• Reduce light-induced degradation (LID), which improves production stability over time.
• Improve performance in low irradiance conditions or in installations with reflective surfaces.
• Better performance at high temperatures.
• Greater long-term production stability.

This bifacial technology allows light reflected from white roofs or light surfaces, gravel or reflective floors, elevated structures, and above-ground installations to be used.

Under favourable conditions, this can increase the effective power of the module with respect to its nominal value, improving the annual yield of the installation.

Design and aesthetics

The solar panel is constructed with high quality materials and a double glazed structure.

The Full Black configuration (both cells, frame and rear surface in black) not only provides a more uniform and unobtrusive appearance, but is also particularly valued for its durability and mechanical stability.

Its half-cell design (108 split cells) reduces internal resistance losses and improves performance in partial shade situations, increasing the overall efficiency of the module.

Thanks to its glass-glass construction of 1.6 mm + 1.6 mm, this plate provides a high level of protection:

• Increased mechanical strength
• Improved moisture and corrosion resistance
• Increased long-term structural stability
• Less degradation over the years.

In addition, the design and installation features an IP68-protected junction box, MC4-EVO2 compatible connectors, and 1200 mm cables for easy installation.

High power and efficiency

The JA Solar Panel is designed to provide a nominal output of 450 W, but as it is a bifacial module its actual output can increase when there is back irradiation.

Therefore, this 450W solar panel would be left with an approximate output of 486W, showing the extra potential in favourable locations.

It is also notable for its high energy efficiency of 22.5 %, which means that it converts a higher proportion of the available sunlight into useful electricity.
This allows more energy to be obtained per square metre installed, reducing the number of panels required and thus optimising both space and installation costs.

Optimised performance

This solar panel is designed to maintain its performance over a wide range of environmental conditions:

• Wide operating temperature range (-40º C to +85º C), This ensures that the solar panel can operate reliably in both cold and hot climates.
• Low temperature coefficient (-0.29 %/°C in power), This means that the power loss on hot days is lower compared to modules with older technologies, guaranteeing a stable output even in summer.

These attributes ensure that the plate maintains its efficiency even when conditions are not ideal, providing more stable and continuous production over time.

In addition, the 450W JA solar panel in installations with long strings allows a maximum system voltage of 1500 V DC, and a maximum series fuse of 30A.

Strength and durability

The solar panel is constructed with high quality materials and a double glazed structure, which increases the mechanical resistance to environmental loads (such as strong wind or snow) and improves the overall durability of the module.

Its resistance is 5400Pa for front loading and 2400PA for rear loading.
Therefore, these characteristics allow installation in demanding environments in complete safety.

In addition, the technology used reduces the degradation of the module over time (1% in the first year and 0.4% per year), which means that the actual production in year 30 of operation will still be significant.

This guarantees stable and predictable production for decades.
