innovative solution for a cleaner tomorrow

Mitsubishi

Mitsubishi Electric has been in the solar electric field since its infancy in the 70s, when they made the first solar panels to provide power to satellites. They continue to lead the industry with their photovoltaic modules, designed for both commercial and residential grid-tie applications. Mitsubishi solar panels offer both high performance and reliability and meet the requirements of international quality standards. (UL 1703, IEC 61215, TÜV Safety Class II).

Mitsubishi Electric has perfected a manufacturing process that limits the use of harmful lead solder by using silver electrodes on the surface of their solar panels. This proprietary technology makes their panels especially weather resistant. It also allows panels to uniformly reflect the sun’s rays, improving cell efficiency. Solar panels with high efficiency make the best use of limited space, and lower costs by reducing the number of modules needed. Their newest panels boast an efficiency rating of 16.2 percent.

  • Warranty: First 10 years at 90% output / 25 years at 80% output

Superior Technology

Half-cut Cell

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%.

Cells are cut with a special process using a high-precision laser to maintain the integrity of the cell.

By using half-cut cells, the electrical current ( i ) flowing in each busbar is halved. Therefore, the amount of internal losses in a half-cut module is 1/4 of a full sized cell module.

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.

Newly Re-designed Junction Box

Our field-proven high safety junction box has been re-designed and optimized for use with monocrystalline cells. 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.

Anti-reflective Glass

An anti-reflective coating has been added to the glass of our modules. It improves the light transmittance of the glass by reducing the amount of reflection on the surface. This improvement has led to a module output increase of 2%. Furthermore, Mitsubishi Electric modules use a non-porous type of anti-reflective coating, which is more resistant to the adhesion of dust than porous types.

Anti-reflective Glass

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.
