photovoltaic cells: Mitsubishi Electric photovoltaic modules

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

Eco-factory
Mitsubishi Electrics 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. In addition, we use recyclable steel pallets to transport our modules instead of wooden pallets that break and end up in landfills.

Five percent energy reduction during manufacturing
We have simplified our manufacturing methods in ways that 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.

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.

Solder-less Cells
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. Weve even achieved higher PV module conversion efficiency, taking advantage of the new products ability to more uniformly reflect the suns rays.

Lead-free solder
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.

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.
