Pros
Young inspired team with some older folks to keep the lid screwed on. Elon Musk is a great leader for the company as are his cousins Lyndon and Peter Rives. It really is working for an industry visionary and it helps to be able to say you work for an Elon Musk company. Benefits are decent and work conditions are about what you find in any fast moving company now. Bummer I had to give up my old office. People have respect for the company in the industry and that is much better and easier than working for a company no one has heard about. We are changing the energy industry with new products and new technology. SolarCity leads. I think there are some good opportunities for growth in the company. There are some really smart people at the company and yet you don't have too many ego maniacs. That was the case at another large solar company I worked for.
Cons
The company is growing really fast which can cause you to lose your way, My sense is salaries are lower than other companies. It Is no longer a small company so you have the growth issues.
