If investors merely went by labels in making buy-sell decisions, SolarCity would have been doomed by its name. Companies involved in solar energy have been toxic on Wall Street of late. The culprit has been cheap solar panels from China that have whacked established manufacturers, like First Solar, and rendered stillborn well funded startups, including Solyndra (now bankrupt) and Miasole (recently sold on the cheap). SolarCity has thrived because it buys solar panels and then installs them for its mostly residential customer base in 14 states.
