Honda flipped the switch on a new solar energy system at the American Honda Motor Co., Inc. campus in Torrance, California, one of the largest solar arrays on a commercial building in Southern California, and at 2 MWdc, one of Honda’s largest on-site renewable energy installations anywhere in the world. The new solar array expands Honda’s ongoing commitment to reduce its environmental footprint by developing and implementing renewable energy projects throughout its operations. A time-lapse video of the solar rooftop installation is available at https://youtu.be/2OFqnhWpN0I.
Honda’s new solar array features more than 6,000 panels and is expected to generate approximately 3,000 MWh annually. It will offset roughly 30% of the purchased electricity for the entire American Honda Torrance campus. Solar energy also will provide 100% of the electric vehicle charging energy in the parking lot to the south of the solar rooftop system. A Honda-developed cloud-based energy management system can control electric vehicle charging to match solar generation at the 60 EV charging stations to maximize the amount of solar energy used to charge the vehicles.
The solar array on American Honda’s Torrance campus is connected in parallel to three large lithium ion batteries that improve the integration of renewable energy with the electric grid, smoothing out the abrupt changes in power generation that occur, for example, when a cloud covers the sun. The batteries—a 500 kW / 1,000 kWh and two 100 kW / 200 kWh batteries – also even out the buildings’ power usage and reduce demand charges, resulting in significant utility cost savings.
“Installing the solar and battery system on Honda’s Torrance campus is a win-win-win solution that will help Honda reach its renewable energy goals, save money and reduce CO2 emissions,” said Ryan Harty, manager of connected and environmental business development and engineering at American Honda. “Charging electric vehicles with sunshine is also very satisfying for our associates. The transition to renewable energy and electric transportation go hand-in-hand.”
Increasing the use of renewable energy to meet Honda’s operational power needs
Honda is targeting a 50% reduction in its total company CO2 emissions on a global basis by 2050, compared to the year 2000. To help reach this goal and advance the company toward its vision of creating a carbon-free society, Honda is implementing renewable energy projects throughout its operations.
Recently, Honda partnered with the Bosch Building Grid Technology (BGT) group to deploy a low-cost, high efficiency, commercial-scale direct-current (DC) microgrid platform at the American Honda parts distribution center in Chino, Calif. The DC microgrid enables the distribution center to use and store 300kW of DC connected solar power directly without exporting it to the electric grid. The DC microgrid powers LED lighting, ventilation fans, forklift charging, and other loads in the facility. The microgrid uses a 546kWh lithium ion battery to provide reliable power to the loads, resilience during power outages, increased energy efficiency, and optimized renewable energy utilization. From both an electrical load perspective and by facility square footage the installation is the largest commercial-scale DC microgrid in North America. The Chino facility is also home to an existing 1.0MW solar array, completed in 2016, that provides more than 1,400 MWh of solar energy every year. Combined with the new DC microgrid, Honda expects that 100% of the electricity used by the Chino distribution center will be generated from on-site solar power, meeting the State of California’s 2030 Zero Net Energy Commercial Building goal.
In 2015, Honda installed a 1.1-MW rooftop solar array at its 400,000 square-foot parts distribution center in Windsor Locks, Connecticut. The array of nearly 5,000 high-efficiency photovoltaic panels generates approximately 1,400 MWh of energy annually, meeting more than half of the site’s total electricity needs.
In addition to solar energy, Honda is the first U.S. automaker to derive a significant amount of power directly from on-site wind turbines. Two wind turbines at Honda’s transmission plant in Russells Point, Ohio supply approximately 10 percent of the plant’s electricity. Based on their location and actual wind speeds, combined output from both wind turbines is estimated at 10,000 MWh per year.

Honda commitment to the environment
Based on its vision of “Blue Skies for our Children,” Honda is working to advance technologies that address society’s environmental and energy concerns. Honda is targeting a 50 percent reduction in its total company CO2 emissions on a global basis by 2050, compared to 2000 levels. The company also strives for significant growth in electrified vehicle sales, beginning with the hydrogen-powered Clarity Fuel Cell vehicle launched in 2016, followed by a new Clarity Electric and Clarity Plug-In Hybrid in 2017.
Honda also is endeavoring to reduce the environmental impact of its products throughout their life cycles, including the reduction of energy use and emissions from its production, distribution and sales. This includes the Honda Environmental Leadership Award Program.
