FOR IMMEDIATE RELEASE

RSF Social Finance Purchases $9 Million in Solar Bonds from SolarCity

Transaction sparks relationship between social enterprise and clean energy leaders

SAN FRANCISCO, July 23, 2015—RSF Social Finance (RSF) is pleased to announce that it has purchased $9 million in solar bonds from clean energy leader SolarCity, which launched its public bond offering (http://www.solarcity.com/newsroom/press/solarcity-launches-first-public-offering-solar-bonds) to individual consumers in October.

The investment in SolarCity solar bonds is a strong strategic match with RSF’s mission of transforming the way the world works with money. RSF is a San Francisco-based organization that lends money to path-breaking social enterprises, provides impact investing vehicles accessible to a wide range of investors, manages grant funds, and works to build a finance infrastructure that will allow social enterprises to thrive.

“RSF is proud to directly support SolarCity’s work in renewable energy,” said Don Shaffer, president and CEO of RSF. “This contributes to our goal of employing all our assets to create social and environmental benefits. It also is in line with our effort to democratize impact investing. Like RSF’s Social Investment Fund, SolarCity’s solar bonds are available to individual investors with a minimum $1,000 investment. We’re happy to add capital to a fund that offers this opportunity.”

“We’re extremely pleased to have RSF Social Finance join the growing number of investors—including both institutions and individuals—who are getting paid by the sun with SolarCity’s solar bonds,” said Tim Newell, SolarCity’s vice president of financial products. “RSF’s investment in solar bonds is the latest example of their leadership as an institution in defining the future of impact investing. We’re proud to help RSF and their investors achieve their mission.”

RSF favors investments with broad impact. Solar panels, in contrast with conventional natural gas, nuclear and coal power plants, require no water to produce electricity, create no air pollution, and emit no greenhouse gases. The solar industry is also a prodigious job creator—in 2014 it created jobs nearly 20 times faster than the overall U.S. economy (http://www.thesolarfoundation.org/press-release-solar-industry-creating-jobs-nearly-20-times-faster-than-overall-u-s-economy). SolarCity, the largest solar employer in the U.S., has added more than 6,000 jobs in the past year.

RSF purchased the majority of the bonds with its liquidity fund, a largely cash reserve that holds donor advised funds awaiting grant-making. Impact investors have limited options for investing these types of funds, so solar bonds are welcome option. RSF’s solar bond purchase will yield a weighted annual return of 2.61% and help diversify its investment portfolio.


“The solar bonds provide an opportunity for RSF and like-minded individuals and organizations to earn an attractive financial return while helping SolarCity expand its use of the sun’s clean energy to reduce our society’s dependence on fossil fuels for power generation,” said Joe Avenatti, RSF’s senior director of investments. “We look forward to exploring additional ways for our two organizations to work together.”
