Exhibit 99.1

August 1, 2016

Team,

I’m excited to announce, along with Don Kendall and Nancy Pfund, the special committee of our board of directors, an exciting new chapter in our company’s history. Today on our blog we announced that SolarCity entered an agreement to combine with Tesla in a transaction that will create the world’s only integrated provider of clean energy, storage and transportation. I believe this combination helps us accomplish our primary goal—to accelerate the adoption of clean energy and create the most compelling energy company in the 21st century. The future of humanity depends on the transition to clean energy, and we have a significant role to play.

In ten short years, we’ve created the number one solar power provider in America. Now, as we move to introduce a range of new product offerings that will revolutionize the aesthetics, affordability and performance of solar power and battery storage, we are aligning with what I consider to be the most innovative manufacturer and product developer in the world. Together, we are well positioned to lead the world into a new era of cleaner, more sustainable energy generation, distribution and consumption.

We believe that this transaction represents the next and best step forward for our company.

All-Company Meeting and Next Steps

While we are announcing this combination today, we don’t expect the transaction to be completed for several months. The completion of the transaction is subject to the approval of the shareholders of both companies. Until the transaction is completed, SolarCity and Tesla will continue to operate as independent companies, as we always have. To be clear, that means it’s business as usual at SolarCity. The best way you can help is by focusing on your daily responsibilities to help us deliver a fantastic customer experience as we provide more affordable, clean energy.

I know many of you will have questions about next steps. We will be scheduling a special edition of SolarCity LIVE to discuss the announcement and answer questions. Look for a separate email invitation with dial-in instructions later today.

How to Handle Questions from Those Outside the Company

As you have seen, there has been significant media interest in our company recently, and today’s announcement will only serve to increase that. It remains important that we do not comment on the transaction with anyone outside of the company, or in social media or other public forums. Any questions from the media should be immediately directed to Jonathan Bass at press@solarcity.com. Any questions from the financial community should be immediately directed to Aaron Chew at investors@solarcity.com.

Today is an exciting day, and your hard work and commitment have helped make it possible. It’s because of you that we’re the leading solar power provider in the nation, and poised to become the most important energy company in the world.

Sincerely,
