SolarCity is an American provider of energy services, headquartered in San Mateo, California. Among its primary services, the company designs, finances, and installs solar power systems. The company had 9,051 employees as of December 2014.[2]

SolarCity has grown to meet the rapidly growing installation of solar photovoltaic systems in the United States. The overall U.S. market has grown from 440 megawatts (MW) of solar panels installed in 2009 to 6,200 MW installed in 2014.[3][4]

SolarCity is one of the founding members of The Alliance for Solar Choice, or TASC, which is a rooftop photovoltaic power station solar advocacy organization.[5]

SolarCity was founded in July 2006 by brothers Peter and Lyndon Rive,[6] based on a suggestion for a solar company concept from their cousin, Elon Musk, who is the chairman and helped start the company. SolarCity has been the leading provider of residential solar power in California since 2007, its first full year of operation, according to the database kept by the California Solar Initiative[7] and was the number one residential solar installer in the U.S. in 2013, according to GTM Research.[8] In 2013, Solar Power World magazine listed SolarCity as the No. 2 overall solar installation company in the U.S.[9]

In October 2014, SolarCity announced it would be offering up to $200 million in solar bonds to launch a new online website to buy the debt, the first registered public offering of such bonds in the United States.[10]


SolarCity is headquartered in San Mateo, California, but the company uses a distributed service model in which it provides installation from local operations centers.

Products, services and technologies[edit]

Solar leasing[edit]

In 2008, SolarCity entered the solar leasing market with a new solar lease option for homeowners.[11] SolarCity's solar lease can allow some homeowners, by adopting solar power, to pay less each month than they previously paid for electricity from the utility company.[12][13]

Commercial solar[edit]

In May 2008, the company completed what was, at the time, the largest commercial solar installation in San Jose on the North Campus of eBay. That July, SolarCity completed what was then the largest commercial solar installation in San Francisco, for British Motors, consisting of 1,606 solar photovoltaic panels.[14][15] SolarCity introduced new financing options for businesses in 2009[16] and has built multiple solar projects for other large organizations including Walmart,[17][18] Intel,[19] and the U.S. military.[20] On March 21, 2013 SolarCity announced that it would open a new location in Nevada in cooperation with state government.[21]

Electric vehicle chargers[edit]

SolarCity entered the electric car charging business by buying the SolSource Energy business of Clean Fuel Connections, Inc., which was reported to be finalized in 2009[22] and has also announced a partnership with Rabobank to make electric car charging available for free to owners of Tesla Motors' vehicles traveling on U.S. Route 101 in California between San Francisco and Los Angeles. Other cars that can make use of the same charging technology are welcome.[23] In 2011, the company announced it would install electric car chargers that could charge a wide range of EVs in all of its service territories.[24][25]

Energy efficiency evaluations and retrofits[edit]

In 2010, SolarCity acquired Building Solutions, a home energy audit firm, and began to offer energy efficiency evaluations and upgrades.[26] SolarCity worked with Admiral's Bank of Boston in March 2012 to make a new loan available to finance energy efficiency improvements [27] and expanded its energy efficiency services to the east coast.[28]

SolarStrong project[edit]

SolarStrong is SolarCity's five-year plan to build more than $1 billion in solar photovoltaic projects for privatized military housing communities across the United States, announced in late 2011.[29] SolarCity plans to work with the country's leading privatized military housing developers to install, own and operate rooftop solar installations and provide solar electricity at a lower cost than utility power. SolarStrong is ultimately expected to create up to 300 megawatts of solar generation capacity that could provide power to as many as 120,000 military housing units, which would make it the largest residential photovoltaic project in American history if completed. In November 2011, SolarCity and Bank of America Merrill Lynch announced that they have agreed to terms on initial debt financing for SolarStrong.[30]

Energy storage[edit]

Tesla Motors and Panasonic will open a battery factory in Nevada in 2017, and plan to make a battery storage device called Powerwall that stores solar power for use as a battery backup. The device will be sold to companies including SolarCity.[31][32] SolarCity is running a pilot project in 500 California houses, using 10-kilowatt-hour battery packs.[33][34]

Installation technology[edit]

SolarCity provides technologies for mounting solar panels on rooftops developed by Zep Solar, which it acquired in 2013.[35] Zep is best known for inventing a system that allows PV installers to "snap together" panels on the roof more quickly than other installation approaches to shorten installation time.[36] Zep Solar's technology eliminates the need for mounting rails on many roof types.[37]


Solar City has sued Salt River Project, an electric utility, for violation of the Sherman Antitrust Act. This is in response to Salt River imposing a peak demand based charge on residential customers who also have solar panels.[38]

Project financing and the Google Fund[edit]

SolarCity partners with banks, large corporations, and the asset-backed[39] market to create project finance funds to finance its lease and PPA (Power Purchase Agreement) options. SolarCity's financing partners have included Bank of America, Merrill Lynch, Citi, Morgan Stanley, National Bank of Arizona and U.S. Bancorp, among others.[40][full citation needed] Among SolarCity's more well-known financing partnerships was a $280 million fund created with Google to finance residential solar installations in June 2011. The Google Fund was the largest fund of its kind in the U.S., and Google's largest investment in clean energy.[41]

Recently, securitization has been proposed and used to accelerate development of solar photovoltaic projects by providing access to capital.[42][43] SolarCity offered the first U.S. asset-backed security in the solar industry in 2013.[44]


In June 2014, SolarCity announced plans to build a new manufacturing facility in Buffalo, New York, in coordination with the SUNY Polytechnic Institute after acquiring Silevo, a maker of high-efficiency solar modules. With a planned capacity of one gigawatt of solar panels annually, the new plant would be the largest solar plant in the U.S. and would compete head-to-head with Chinese manufacturers.[45] Groundbreaking for the project occurred in September 2014 with a target completion date of early 2016.[46]

The facility is expected to be the largest of its kind in the Western Hemisphere.[47][48]
