Higher Cell Efficiency
4 Busbar Cell
Through an industry-leading innovation of integrating four busbars into each cell, internal electrical resistance is reduced, boosting cell output by 3%.
Because the distance between bus bars are shorter, the flow of electricity faces less resistance along the electrodes.
Thinner Tab Strings
Although the number of tab strings have increased from two to four, the widths of the tab strings have been narrowed, thereby allowing the same surface area exposed to light.
Higher Module Output
Highly Reflective Back Film
Use of a highly reflective back film in combination with a high cell pitch allows more light to be reflected onto the cells, contributing to higher efficiency.
The backfilm is also designed to be a highly effective moisture barrier for long lifetime protection.
Cerium-free High-transparency Glass
Our modules utilize high-transparency, cerium-free glass to achieve high efficiency and uncompromising strength.
New I-frame Design/Protection Bar
Building upon our already track-proven standard frame, the newly refined I-frame boasts a increase in strength by approximately twofold.
4 Busbar Cell Stress Resistance
The increased number of Busbars per cell enable a more uniform dispersion of stress on the tab. As a result, cells are more durable than before.
Improved Junction Box
The junction box is one of the most critical parts of a module in terms of safety. Safety was given the number one priority when designing our junction box. Newly redesigned junction box features multiple layers of protection against water and other risks.
The new I-frame has grooves for gripping, enabling easier handling of the module. It is especially convenient when stacking multiple modules at the installation site, or when lifting the module from a flat surface such as the ground.
Mitsubishi Electric was the first Japanese company to mass produce lead-free solder modules, making our modules even friendlier to the environment.
