High-Performance 120 Watt Polycrystalline Solar Module with Junction Box
PV-MF120EC4

Mitsubishi Electric’s photovoltaic modules are engineered for extended use in environments with extreme temperatures and harsh weather conditions. These panels utilize polycrystalline technology and are known for their high reliability, high-efficiency, and low environmental impact. All Mitsubishi solar panels feature a 25-year limited warranty on power output and are designed to deliver you trouble-free electricity for years to come.

Features:

• Designed for both commercial and domestic applications suitable for both grid-connected and stand-alone systems, the module offers both high performance and reliability.
• The polycrustalline photovoltaic module is manufactured to the strict engineering guidelines, ensuring all modules meet the requirements of international quality standards.
UL 1703/IEC 61215/TÜV Safety Class II
• High power output is achieved using 150mm square polycrystalline silicon cells, thereby achieving greater output due to the high comerage area of the individual cells. Each cell string is protected bu sheets of ethylene vinyl acetate (EVA) and laminated between a weatherproof backing film and a highly transmissive, highly impact-resistant, tempered glass and light can be effectively converted to electricity by using an anti-reflection coating.
• The clear anodized aluminum alloy frames are robust and corrosion resistant.
• Bypass diode minimizes power decrease caused by shade.
• Frame holes make installation flexible.

Solder-free Cells

The silver electrodes formed on the solar cell surface excel in environmental resistance. This has paved the way to the industry-first introduction of mass-produced “solder-coating less cells” — which, as the name suggests, require no solder coating. This removes lead which is harmful to the human body, while the expanded light reflection effects with the solderless status improve cell efficiency.

Mitsubishi Electric has 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.

High Efficiency

This solar panel's efficiency is 13% using polycrystalline silicon 150mm square solar cells, 36 in series. This module will work well with battery back up systems and utility grid-tie systems.

High Power Output in Actual Use

Mitsubishi Electric determines the output measurement of photovoltaic modules by using calibrated modules at JRC, a leading European testing institute. We also exercise meticulous controls on the production line, working to ensure that factory-shipment test values exceed the nominal output power for each carton (two modules per carton). These efforts combine to realize high power generation performance in actual use.

Eco-Friendly

Mitsubishi Electric photovoltaic modules reflect a proactive approach to environmental regulations, and the determination to supply outstanding environmentally-friendly products. As a large-scale manufacturer with a keen awareness of our responsibility to the environment, Mitsubishi Electric is committed to the development of cleaner, more efficient manufacturing methods, and actively takes a leadership role. For example, in January 2003 we became the first among Japanese crystalline silicon photovoltaic cell manufacturers to begin volume production of solder-less cells and modules with lead-free solder.

Lead-Free Solder Solar Panel

Mitsubishi Electric has made a commitment to protect the environment. We are proud to be the first photovoltaic (PV) manufacturer to use lead-free solder in our modules. While traditional lead-solder modules use about 860 grams of lead, Mitsubishi Electric modules have 0 grams of lead. Using newly developed silver electrodes that offer superior weatherproofing, Mitsubishi Electric has perfected a technology for producing photovoltaic cells that does not require solder coatings. 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. Traditionally, lead-solder coating has been required to ensure that PV modules are weatherproof and remain moisture-resistant for years on end. By developing environmentally friendly composite materials and manufacturing processes for silver electrodes used on the surface of crystalline silicon photovoltaic cells, Mitsubishi Electric has succeeded in producing cells that do not require a solder coating.

Five percent energy reduction during manufacturing

Mitsubishi's simplified manufacturing methods create a better product while increasing productivity. Reliable, lead-free fabrication techniques that do not use solder coating improve the power efficiency of each individual cell. They also reduce work steps to provide for greater manufacturing yield. Overall, this realizes a five percent reduction in energy use during the manufacturing process.

New Steel Pallet and Other Environmental Standards

Mitsubishi Electric's photovoltaic product manufacturing plant is certified under the ISO 14001 environmental standard, and also features comprehensive water-conservation and recycling measures. We are advancing production operations with meticulous care for the environment. Recyclable steel pallets are used to transport solar modules instead of wooden pallets that break and end up in landfills.

Mitsubishi Electric understands that the key to protecting our planet while improving our lives is to use clean renewable energy, the way nature intended.
