Mitsubishi Electric is a worldwide leader in the development and production of energy generating systems that protect the environment. Decades of experience in electronics and electrical applications have facilitated the development of high performance photovoltaic system components. Mitsubishi Electric is one of the few module manufacturers that have applied new technology to utilize lead free solder in the stringing and soldering of their cells. This process saves over a kilogram of lead for modules with an output of 3.5 kWp.
