Mitsubishi Electric is dedicated to bringing you the latest in solar electric technology. Their state of the art research and development facilities are constantly discovering new ways to improve PV module efficiency and performance to maximize the amount of electricity your solar system can produce. Modules with high efficiency not only make effective use of limited space, but also contribute to lowering cost by reducing the number of modules in use.
For the silver electrodes formed on the solar cell surface, we have succeeded in developing a composition and manufacturing process that excel in environmental resistance. This has paved the way to the industry-first introduction of mass-produced “solder-coatingless 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.
Adoption of an optimal BSF structure has broadly improved solar cell efficiency.
Use of anti-reflective coating shuts out solar rays that reflect off solar cells, thereby heightening cell efficiency
A unique new bus bar design dramatically improves module efficiency by reducing bus bar series resistance
Solar cell string pitch have been expanded, with back film reflected light mobilized to raise module efficiency.
The newly developed high reflectance back film improves module efficiency by increasing reflection power from 80%* to 90%*. (*evaluated by Mitsubishi Electric)
Use of glass that is cerium-free and high in transmittance has defined a new dimension in high efficiency, free of initial deterioration.
Mitsubishi Electric’s state-of-the-art production management system can provide the tightest tolerance of module output power (+/-3%) in the industry. This innovation can be expected to higher output power in your PV system by reducing module string losses.
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.
