The PV systems market has been rapidly expanding globally due to increasing environmental concerns, as seen in worldwide efforts to reduce carbon dioxide emissions to prevent global warming. The PV market of the USA, in particular, has been gaining greater momentum with the introduction of environmental initiatives within the new stimulus plan, and enhancements in government subsidies.

Mitsubishi Electric expects the USA market volume to surpass 1 GW by 2012, with stand-alone systems that power streetlights, traffic lights, water pumping systems for sprinklers and other equipment making up 20% of the demand. Meanwhile, countries in Asia and Africa with areas that lack power plants, power lines, and other infrastructure are promoting projects to install stand-alone PV systems in order to meet electricity needs. Mitsubishi Electric’s new lineup of PV modules for stand-alone systems consists of models with outputs from 115W to 130W. Compared to the company’s previous models, the new models have specifications more suitable for off-grid installation environments in the midlands of the USA and remote areas in developing countries.

Mitsubishi Electric will attempt to meet the diverse demands of various countries and usage patterns. Mitsubishi Electric plans to expand its annual production capacity to 600 megawatts in fiscal 2012 (April 1, 2011-March 31, 2012). The company has also enhanced its PV business by forming a new division, the Photovoltaic Systems Division, in the Living Environment & Digital Media Equipment Group as of April 1, 2009. Mitsubishi Electric will continue to promote PV systems worldwide, thus contributing not only to the prevention of global warming in developed countries, but also to enhance social infrastructure in developing countries. 

Main Features

1) Junction box dedicated to stand-alone PV systems makes installation easy and enhances safetyThe new models are equipped with a junction box dedicated to stand-alone PV systems, taking into consideration the remote installation environments that they are often used in. The lid does not separate from the box, and can stay open at a fixed angle, enabling easier cable installation. This junction box was first adopted in Mitsubishi Electric’s small-size PV modules announced August 27, 2008, with its patents pending.

A highly flame-retardant mica sheet has been added to the inside of the junction box lid, enhancing safety. In the rare event of fire caused by a faulty or incorrect connection when installed, the sheet will prevent flames from spreading outside the junction box. 2) Power voltage appropriate for stand-alone systemsThe modules each consist of 36 PV cells, and their operating voltages are suitable for a 12V rechargeable battery, which is most widely used in stand-alone PV systems. 3) Lead-free solder reduces negative impact on the environmentThese modules use solder containing zero lead (0g), minimizing negative impact on the environment.
