The Plan for Solar City to go Public with an IPO does will make good economic sense to an investor. From a practical standpoint Solar City apparently is looking for a way to convert their debt to equity and put the risk with the investors. My best guess is that there is a lot of high priced debt that will come due in the next two years and Solar City is looking for a way out. I could be wrong but my best gues is that the IPO will not be well recieved.
