Our focus for this list was PV modules/solar cell manufacturers, solar mounting system suppliers, solar glass and component manufacturers, cell manufacturing equipment companies, and utility-scale project developers. An average company in this list will have sales of around $9 million and 90 employees.

The list was compiled by reviewing various trade journals to identify the top players in the U.S. solar market. We reviewed the company’s website, press releases, and news events to determine whether the company is, in fact, directly in the solar business.

Why Solar?
The solar industry in the U.S. has become one of the strongest job creators in the country. With over 17,000 direct jobs added in 2009, and a further 14,000 estimated to be added in 2010, it is one of the few industries to grow during the great recession of 2008-2009.
According to Solar Energy Industry Association, at year-end 2009, the U.S. had 2,108 megawatts (MW) of installed solar electric capacity. This included about 1,676 MW of photovoltaics (PV), 432 MW of utility-scale concentrating solar power, and at least 24,000 MWTh (megawatts thermal equivalent) of solar water heating, cooling, and solar pool heating systems. Installations have been on the rise since 2005 when the solar industry took off in the country. The chart below shows the growth of solar electric installations in the U.S.

Further proof that the solar industry is one of the most active sectors is given by an analysis of Conway Data. Conway tracks new and expanded project announcements globally and is one of the most commonly used sources to track project activity.
A total of 30 new projects and 17 expansions of solar product manufacturing facilities were recorded by Conway Data in 2009. These projects resulted in $4.6 billion in investment and created approximately 8,000 new jobs. The chart below shows the growth of solar projects in the U.S. since 2003.
Along with the number of projects, the number of jobs created by the industry has also increased dramatically over the last seven years. While there were just four projects creating 635 jobs in 2003 in the country, in 2009 there were 47 projects creating around 8,000 jobs. The chart below shows the progression of jobs created by the solar industry in the U.S.
