The solar industry in the United States can be broken into sectors focusing on residential rooftop installations, mid-sized commercial installations and large ground mounted projects that are essentially power plants. There are over 9,000 solar companies in the U.S. spread across every state, and the industry employs 250,000 Americans as of 2018. Interestingly, for comparison, there are 50,000 coal mining jobs.
Although there are more residential solar installers than solar farm companies, the large farm projects account for over half of the total solar Megawatts constructed annually. Solar farm companies are said to be in the ‘utility-scale market’ and can be loosely categorized as manufacturers, construction companies and developers.
