As stated in my post that initiated this thread, discussion of other solar companies should only be made in reference to how they might affect SolarCity and its shares. Otherwise there is a thread in this forum titled "Alternative Energy Investor Discussions". It was originally a SCTY thread but got hijacked by discussion of other solar companies and SCTY got drowned in the noise. That's the reason I initiated this new SCTY thread last March.
As I expressed in post's #903 & #905, I was holding off on reentering SCTY due to the possibility that some investors wanting to buy VSLR would sell some of their SCTY shares and depress SCTY's price. Apparently you would use new cash to buy VSLR. I can't quarrel with diversification, but keep in mind that yours is money that would not be used to support the SCTY price.
