MONOCRYSTALLINE

Solar Power Systems

Mitsubishi Electric's philosophy for manufacturing photovoltaic products comes from three unwavering basic principles: advanced technologies, the highest quality, and long-term reliability. We integrate all of our photovoltaic product development and manufacturing operations at our own facilities in Japan.

Supply Electricity to Remote Communities

At Mitsubishi Electric Asia, we provides design, installation, testing and commissioning services to potential customers in Asia. In additional to promoting clean electrical power, the provision of electric supply to remote communities is also one of the goals. Mitsubishi Electric photovoltaics modules are widely used by rural communities in Cambodia, Laos, Indonesia, Malaysia, Philippines, Thailand, Vietnam and others.

Features

Technology
Mitsubishi Electric is constantly pursuing the latest in technological innovations and adapting the newest breakthroughs into our photovoltaic products.

 

Selective Emitter
In a standard doping process, silicon wafers are doped with phosphorus to create a P/N junction. The level of doping concentration was a trade-off between conductivity with the cell electrodes and carrier charge recombination. Higher concentration levels leads to higher conductivity, but more carrier charge losses, and vice versa. As a solution, Mitsubishi Electric has introduced a new selective emitter process in which only the area in contact with the electrodes is doped with high concentrations to maintain both high conductivity and low carrier charge losses. This improvement has resulted in an increase in cell output of approximately 5%.



4 Busbar Cell
Through an industry-leading innovation of integrating 4 busbars into each cell, internal electrical resistance is reduced, boosting cell output by 3%*. This is possible because the distances between the busbars are shorter and less current flows through each smaller electrode where resistance is the highest.



Lead-free Solder
Mitsubishi Electric was the first Japanese manufacture to introduce (and still use) 100% lead-free solder in the inter-cell connections as another initiative contributing to environmental protection


Quality
Total quality from design to manufacturing ensures optimal performance and safety of our products in the real world.

 

Taguchi Method
Mitsubishi Electric takes pride in researching, designing, manufacturing and assembling all of our photovoltaic products from the cell to the module in our own facilities located in Japan. By taking total control, we can optimize each step of the production process to ensure the highest quality of our products.

 

Production from the Cell to Module
By reducing the area of each cell and connecting them in a parallel formation, the amount of electrical current carried by each busbar is reduced by half. This results in the decreased of electrical resistance within the busbars and an increase in overall efficiency of about 2.5%.



Highly Automated Production Line
From assembly to inspections, our module lines are highly automated with our own factory automation equipment developed in-house. For example, using ccd camera imaging to align busbars for soldering or to detect mispositioned cells in an array, the high precision machines ensure an unsurpassed level of production uniformity and the ability to conduct greater quality inspections than traditional manual methods.





Reliability
Building upon almost a century of manufacturing experience since our founding in 1921, we know how to make our products last. Rest assured that we will be there for our customers in the long term.

 

Improved Frame
Our classic hollowless L-frame design has been improved with a smarter protection bar insert. As a result, the strength of the new frame has increased by approximately double that of the previous L-frame. In addition, modules can now be installed by clipping the shorter sides, simplifying system design and installation.

 

Double Corrosion-resistant Frame Coating
The highly durable aluminum frame is treated with two separate corrosion-resistant coatings for excellent durability and a beautiful finish. Even the individual screws have double anti-corrosive coatings for lasting protection.



4 Busbar Cell Strength
The 4 busbar cell has a more uniform tab stress dispersion than cells with fewer busbars. Because the stress peaks of the cell are lower, it is less prone to cracking.



Internal Testing Standards
At Mitsubishi Electric, our philosophy is to make products that will last. As PV modules are no exception, we have tested our monocrystalline modules with very rigorous internal testing, using strict parameters that are well above than those required by international standards. Only after we have confirmed the reliability of the module's design is it allowed to be introduced into mass production.



Installable in Areas with High Salt Concentration
Normally, high salt content in the air (in areas such as next to the ocean) can do serious damage to the structural integrity of a PV module, and can also pose an electrical safety hazard by causing corrosion. However, due to the intelligent design and high quality of the materials used, our modules can be safely installed in such areas with high salt concentration in the air*.

*Excluding areas in which the module comes into direct contact with salt water.
