All models made in Japan
Mitsubishi Electric Quality
All of our photovoltaic modules, from the cell to
the module, are made in our own factories in
Japan
Highly automated production lines ensure a
stable level of high quality for every module
Cells are matched for uniformity before module
assembly
Each pair of modules is selected to have a higher
average output power than the nominal value
