Competition and Market Share

Evergreen Solar is still a relatively small player in the solar market, and sells a technology type (String Ribbon) that is younger than most other solar power technologies. Other competitors, with 2005 market shares[1], include:

  • SunPower (SPWR) (insignificant in 2005) - One of the fastest growing solar companies, with one of the most efficient cells around
  • Sharp Electronics (24%) - The largest photovoltaic cell manufacturer in the world.
  • Suntech Power Holdings (4%) - A Chinese photovoltaic cell company that is muscling its way into world solar markets.
  • JA Solar Holdings, (insignificant in 2005) - A Chinese PV company that only sells monocrystalline solar cells; it lets its customers take care of building the modules and systems.
  • Solarfun Power Holdings (insignificant in 2005) - Another Chinese PV company that operates 90% in Europe and makes most of its money by selling modules, rather than individual cells.
  • Kyocera (8%) - A Japanese electronics company that is also a manufacturer of solar cells
  • Q-Cells (9%) - A privately owned, German solar manufacturer
  • First Solar (insignificant in 2005) - A thin cell solar panel manufacturer that uses cadmium telluride instead of silicon for its cells.
  • BP (5%), Mitsubishi (6%), and Sanyo (7%) - Not primarily photovoltaic cell manufacturers, but heavy market competitors nonetheless.
  • EMCORE (insignificant in 2005) - A Concentrated Photovoltaic System manufacturer that uses Gallium arsenide PV cells and got its start in the solar business making power cells for satellites.
  • Energy Conversion Devices - This company uses amorphous thin-film silicon in its ultra-thin, albeit low-efficiency solar cells.
