Suniva is the only crystalline solar Solar Companies in the US which has been able to survive and thrive in recent times.Sunpower too has resurrected itself through strategic JVs and acquisitions.The main reason for the decline of the US solar companies has been the severe competition from the low cost Chinese Solar Industry.This has made companies like Energy Conversion Devices and Evergreen Solar shut down US factories and look towards Mexico and China to build low cost factories.However Suniva has managed to face all these competitive threats quite successfully and is looking to expand capacity in the US by building a 400 MW factory.The company even refused a DOE Loan Guarantee saying that the terms were too onerous.The company has manged to raise more then $130 million in equity and has won contracts to supply high efficiency solar cells to the Asian companies which is a first.Suniva differentiates itself through its technology which allows the production of high efficiency monocrystalline solar cells at lower cost.Note Sunpower makes the highest efficiency cells in the world in the range of 22-24% but its cost structure is too high.Suniva is looking to challenge the Taiwanese Cell Producers by marrying higher efficiency with lower cost.
