Mitsubishi Electric Solar Panels -- High Efficiency & Durability These modules are engineered for extended use in environments with harsh weather conditions and extreme temperatures. Utilizing polysilicon technology, these Mitsubishi photovoltaic modules are known for their high reliability and high-efficiency. They even have a lower environmental impact than other solar panels. Warranty25-year limited warranty on power output. These panels are designed to deliver you trouble-free electricity for years to come. Download Warranty details. Exciting new technology- Solder-free Cells Mitsubishi has developed a composition and manufacturing processes that excels at environmental resistance and efficiency, regarding the silver electrodes formed on the surface of the solar cells. This has paved the way to the industry-first introduction of mass-produced “solder-coatingless cells”.  As the name suggests, these special cells require no solder coating. This eliminates lead, which is harmful to the human body, while the expanded light reflection, with the solderless status, improves cell efficiency..Back to Top

Features & Attributes

  • Dimensions (LxWxH): 25.4 × 2.2 × 56.1 inches
  • Weight: 25.4 lbs
  • Lead contents: 0 g*. A new form of photovoltaic power generation, even friendlier to the environment.
  • Previously, the total amount of lead used in the photovoltaic modules required providing power to single residence (using a 3kw system) was around 864 g. The new lead-free solder modules use no lead whatsoever.
  • lead volume used in soldered parts
  • No solder coating required for cells-for higher PV module conversion efficiency. Using newly developed silver electrodes that offer superior weatherproofing, We've even achieved higher PV module conversion efficiency, taking advantage of the new product's ability to more uniformly reflect the sun's rays.
  • Designed for both commercial and domestic applications suitable for both grid connected and stand-alone systems, the module offers high both performance and reliability.
  • The polycrystalline photovoltaic module is manufactured to the strict engineering guidelines, ensuring all modules meet the requirements of international quality standards.
  • UL 1703/IEC 61215/TUV Safety Class II
  • High power output is achieved using 150mm square polycrystalline silicon cells, thereby achieving greater output due to the high coverage area of the individual cells. Each cell string is protected by sheets of ethylene vinyl acetate (EVA) and laminated between a weatherproof backing film and a highly transmissive, highly transmissive, highly impact- resistant, tempered glass and light can be efficiently converted to electricity by using an anti-reflection coating.
  • The clear anodized aluminium alloy frames are robust and corrosion resistant.
  • Bypass diode minimizes power decrease caused by shade.
  • MPN: MF120EC4

About Mitsubishi

Mitsubishi solar panels

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 both for 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 13.7 percent.

Further environmentally friendly innovation has reduced the energy it takes to produce their panels.

TECH TIP: The 170-watt and larger modules are designed for use in high-voltage grid-tie applications, but can be used in large industrial and off-grid applications for battery charging with the appropriate MPPT charge controller.)
