Large Photovoltaic Solar Power Player

I am curious on who is the largest companies. The issue or challenge seems to be in measuring it. Is it by power produced, revenue, number of employees, or ?

In no particular order:

• REC. - Norwegian company. Claims to be #1
• First Solar - Helped by Walton family.
• SunTech - Claims to be #3
• Kyocera - Large Japanese Solar producer. Large factory in San Diego.
  
• Sharp - Developed first usable photovoltaic module from Silicon.
• Sanyo - Large Japanese Solar producer. Large factory in San Diego.
• BP Solar - Large player who has been around a while.
  
• Siemens Solar Industries - Bought Arco Solar in 1990. Also one of the largest solar producers.
  
• Solar World - Formerly Shell Solar
• Sun Power - TJ Rogers with Cypress Semiconductor helped the company.
• Q-Cells - Start up.
• Evergreen Solar - Start up
