your opinion is no better than anyone else's.

As far as I am concerned SPWRA and TSL are global leaders, CSIQ is also a respected player but your other choices are seriously flawed compared to SPWRA, TSL and CSIQ...JMHO...by the way you should check the facts, SPWR produces the most efficient and sophisticated solar systems in the world...its sales are nearing 2 billion...Richard Swanson, president and chief technical officer of SunPower Corporation, received The Economist's Energy and Environment Innovation Award for 2009.

Swanson is one of the world's most recognized leaders in the advancement of photovoltaics (PV) and a pioneer in commercializing cost-effective PV power systems. In 2006, he was honored with the prestigious Becquerel Prize for Outstanding Merits in Photovoltaics, and in 2002 he was presented with the William R. Cherry Award by the IEEE for outstanding contributions to the PV field.

TSL is closing in on a billion in sales...so dont knock success, it makes you look foolish... the stock market is beyond rational comprehension...you take your risks... I like investing in solar for America's energy independence and because I want clean energy period.
