I am not familiar with CSUN...
I currently own CSIQ, STP, CSOL and WFR. SPWR was my biggest holding in my PF till it ran up and i sold. Looking to reenter but it is a choppy market and tough to know when and where to jump. Have a special wall in the house to beat my head against for not buying TIM and FSLR, and may buy those 2 as well.
should note that FSLR and TIM have both been reccomended by analyists on BNN in the last couple days.
