Solar City did pull permits to install solar panels on my house but they never did the install. I had a terrible experience with them. They never kept in contact with me on when they were planning on starting the project. I started the process with them in August 2016, and by January 2017, the project had not even begun. I had to call them every time I wanted to find out what was going on rather them calling me to provide me with updates. I finally called the project off in the middle of January and went with a different company. I would not recommend Solar City.
