Mitsubishi Electric Powers U.S. HQ With Its Own Solar Modules

Mitsubishi Electric US Inc. has installed a 369 kW solar PV system on the rooftop of its U.S. headquarters in Cypress, Calif. Mitsubishi Electric Corp. was founded in 1921 and manufactures a diverse line of products, including PV modules, automation equipment, escalators and elevators, and heating and cooling products.

The 1,380-module system was installed at its headquarters building, located within Warland Investment Co.’s Cypress Business Park, using Mitsubishi’s 690 Diamond Premium and 690 Diamond Pro modules. According to Mitsubishi, the system can save the company 85% in electric costs, which totals $2 million over the next 25 years. Based on current electricity usage, the system is expected to cover 90% of the Mitsubishi facility’s powers, allowing the system to pay for itself in less than five years.

The system was designed and installed by California-based installer Sun Integration. It includes 10 Yaskawa – Solectria Solar PVI 36TL transformerless, three-phase string inverters along with non-penetrating racking by PanelClaw. The company says the ballasted racking, combined with Mitsubishi Electric’s modules, was key to obtaining a quick approval of the installation by all parties, including building owner, Warland Investment Co.

“Mitsubishi Electric is pleased to contribute to the community and environment by producing clean energy with our own solar modules,” said Kiyoshi Furukawa, president and CEO of Mitsubishi Electric US Inc. “The system proves that businesses can be both environmentally and financially sustainable.”
