Polycrystaline Premium 230W

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.

*Approximate improvement compared to a standard 2 busbar cell.

Quad-layer protective Junction Box

As one of the most critical parts of the module in terms of safety, our junction box features a waterproof, flame-resistant 4 layer barrier of protection. Combined with highly heat-resistant diodes, efficient heat-sink, and secured intertwining tab connections, our junction boxes boast a top-class level of safety.

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, while the expanded light reflection effects with the solderless status improve cell efficiency.

Fine Grid Electrodes

Mitsubishi Electric have developed fine grid electrodes for the solar cell manufacturing process, an advance that has effectively expanded the solar cell light receiving area to realize high-efficiency cells.

Cerium-free/High-transmittance Glass

Through using glass that is cerium-free and high in transmittance we have defined a new dimension in high efficiency, free of initial deterioration.

High power in actual use (Paired module average exceeds nominal value

Working to ensure that factory-shipment test values exceed the nominal output power for each carton (two modules per carton) means these efforts combine to realize high power generation performance in actual use.

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.

High Snow Load

Our modules have been designed to withstand harsh environmental conditions, such as in areas with high snowfall. The high structural strength of the modules has passed the IEC 61215 static loading test at 5400Pa.
