A Legacy of Solar Power Technology
With 90 years of electronics manufacturing expertise and more than 40 years’ experience as a manufacturer of solar power technology, Mitsubishi Electric is one of the most established solar providers in the industry. Mitsubishi Electric US, Inc. is an affiliate of Mitsubishi Electric Corporation, a $40 billion company that invests $2 billion in R&D annually, including innovations in solar technology. Our photovoltaic (PV) modules are backed by the stability of a recognized, global leader in the solar industry.

Mitsubishi Electric’s solar modules are made with 100% lead-free solder to protect the environment and human health. Lead is a heavy metal and is classified as an environmental hazard. It is a material strictly governed by EPA regulations. Mitsubishi Electric pioneered volume production of solar modules with 100% lead-free solder in Japan in 2003. All of Mitsubishi Electric’s solar module product lines avoid the use of lead solder. By contrast, a traditional 50 cell solar module contains 48 grams of lead, while a 580 kW DC photovoltaic array would contain approximately 150kg of lead.
Lead is a poisonous neurotoxin. Even low levels of lead in blood have been shown to affect IQ, ability to pay attention, and academic achievement. The effects of lead exposure cannot be corrected. According to the Center for Disease Control, lead concentration greater than 5 micrograms per decimeter of blood in children is cause for concern.
Lead cannot be removed from a PV module at the product’s end-of-life, therefore it is better to avoid use of lead solder in the manufacturing process. Lead-free solder eliminates leeching or recycling concerns now and in the future. Mitsubishi Electric instead uses silver in its solder, which in addition to not having the toxicity concerns of lead, increases the performance of the module. Lead absorbs radiation, while silver used in Mitsubishi Electric’s solder reflects radiation uniformly to the cell. The silver paste also makes the cell more resistant to moisture.
Our modules are made in solar-powered, ISO 14001-certified factories, which are managed using comprehensive water conservation and recycling measures. Mitsubishi Electric’s Environmental Vision for 2021 includes robust targets for waste reduction, recycling, and decreasing carbon emissions from product production and usage, on which we report annually. While fewer than five Mitsubishi Electric modules per million are returned due to panel malfunction, Mitsubishi Electric US occasionally receives modules damaged during installation. We recycle damaged modules, and encourage our authorized dealers to do the same.
Through the leadership of Mitsubishi Electric US, Inc.’s headquarters Green Team, we have implemented measures to track and reduce office resource use, increase recycling, and adopt re-usable and biodegradable materials. The Green Team also hosts an environmental speaker series to raise employee awareness of sustainability topics, incentivizes employees for environmentally-friendly behavior, and sponsors regular community outreach activities that involve our employees and products.
