Solar Means Business: Top Commercial Solar Customers in the U.S.
Solar energy is being deployed on a massive scale by the most iconic brands and best-managed companies in the U.S. in order to help lower operating costs and increase profits. The Solar Energy Industries Association (SEIA) and the Vote Solar Initiative (Vote Solar) have unveiled a report naming the companies using solar on their facilities in the U.S., ranked by cumulative solar energy capacity.
U.S. Companies Deploy Solar Energy from Coast to Coast

What do Walmart, Costco, IKEA, McGraw Hill, Johnson & Johnson and FedEx have in common? They know a smart investment when they see one, and are all adopting solar energy in a big way. From the largest corporations to small businesses, U.S. companies are installing solar energy to take control of their energy costs and improve their bottom line. As of mid-‐2012, businesses as well as non-‐profit organizations and governments across the United States have deployed more than 2,300 megawatts (MW)1 of solar electric (photovoltaic or PV) systems on more than 24,000 individual facilities—and this number is growing rapidly; during the first half of 2012, over 3,600 non-‐residential PV systems came online, an average of one every 72 minutes. 2
The rapidly falling cost of solar energy has made solar an increasingly appealing investment for American businesses. Between the second quarter of 2011 and the second quarter of 2012, the average price of a completed commercial PV system fell by nearly 14 percent.3 The economics of PV have become so attractive that many of the best managed corporations, which are synonymous with low cost and efficiency, are adopting solar energy on a massive scale across the U.S.
This report, prepared by the Solar Energy Industries Association (SEIA) and the Vote Solar Initiative (Vote Solar), highlights those companies that have deployed the most solar energy capacity at their facilities for onsite consumption. In total, the 42 companies analyzed for this report have deployed at least 321MW of PV capacity at more than 750 locations in at least 26 states and Puerto Rico. The 20 companies with the highest installed capacity have deployed at least 279 MW, enough to supply all the electricity needs of 46,500 American households. These solar leaders include some of America’s most iconic brands and biggest businesses.
In addition to installed capacity, this report also ranks companies by the number of operating installations as well as the geographic diversity of their solar deployment.

Solar Value Proposition
Energy can make up a significant portion of a business’s operating costs. Companies are installing solar at record rates because it reduces operation expenses, improves their bottom line, and allows them to focus resources on their core business strategies.
The price of solar energy systems has dropped rapidly over the past 5 years. In some places, it is more cost-‐effective to deploy solar than buy electricity from the local utility. And no matter where the company is located, solar provides predictably priced electricity for 20 to 30 years. This hedge against utility price volatility is highly valuable to businesses that are focused on managing long-‐term budgets. Combined with innovative financing options that further reduce upfront costs, solar has a new value proposition that makes business sense for major companies nationwide.
Companies across the country have made enormous investments in solar to manage their operating costs. The list above ranks the top 20 of these companies by the installed capacity, or the maximum power potential measured in kilowatts (kW, 1,000 kW = 1 MW), of all of their on‐site solar installations.
Some companies have high energy demand at a single facility and build one or two large systems to meet that need. Others have dozens or hundreds of stores and facilities that could benefit from solar. The rankings above list the Top 20 companies by the number of solar installations at company locations. Those at the top of this list have made repeated decisions to go solar, building off of earlier successes.
Solar Leaders by Percent of Stores
Top Companies by Geographic Diversity
While companies with facilities in California and the Southwest have certainly taken advantage of the ample solar resources and effective solar policies, corporations have gone beyond those well-‐ known solar markets with installations all across the country. Many corporations have solar energy systems in diverse states including Michigan, Wisconsin and Massachusetts, which is a strong indication that solar energy can make business sense in all U.S. climates. This list ranks the top companies by the number of states in which they have deployed PV at their facilities.
The companies ranked here and many more continue to expand their investments in solar energy at a rapid pace. Companies such as Apple, which has a 20 MW system under construction at a datacenter in North Carolina, have announced plans for major solar deployment. Others such as General Motors have decided to enter the solar business themselves.
Businesses as well as other large energy consumers like non‐profits, schools and public agencies are expected to add 7,000 megawatts of additional PV systems over the next five years. That’s enough to replace seven retiring coal power plants.
The Solar Energy Industries Association (SEIA) and the Vote Solar Initiative (Vote Solar) set out to rank the top corporate users of solar energy in the U.S. To do this, SEIA and Vote Solar combed public databases and contacted company representatives to collect data on their use of PV systems.4 While researchers made every effort to collect detailed, complete and accurate data, not every company responded to surveys, and public databases do not capture all installations. Furthermore, new systems are installed every day. In the first half of 2012 alone, over 3,600 individual non-‐residential systems came online in the U.S. Ultimately, SEIA and Vote Solar believe this is an accurate portrayal of the leading corporate users of solar energy in the U.S., but reserve the right to make adjustments as new data becomes available.
SEIA and Vote Solar only counted on-‐site PV systems that supplied power directly to company facilities. This does not include utility PV power plants that sell wholesale electricity. While some companies buy solar renewable energy credits (SRECs) from solar power generated off-‐site, this report does not consider such transactions due to limitations in data collection and verification. Likewise, SRECs produced by many onsite PV systems are sold to utilities or other buyers; while companies that sell their SRECs do not retain the environmental attributes of the system, such systems are still counted for the purposes of this report as the decision to deploy an onsite solar system is an essential step in solar energy development.
Many important companies have made massive investments in helping others go solar. Bank of America, Merrill Lynch, Google and others have provided billions of dollars in financing for solar energy systems in the U.S. While these investments are big business and central to the development of the solar energy industry, they are not the focus of this report.
These rankings only include PV systems that were operational as of mid-‐August 2012.
