SolarCity (NASDAQ:SCTY.DL) has been on a tear this year and is expecting to grow installations as much as 90% next year.

For investors still looking for exposure to solar without the risk posed by SolarCity, SunPower (NASDAQ:SPWR) and First Solar (NASDAQ:FSLR) may be worth a look. Both are profitable and in a more diverse set of markets than SolarCity. Find out more in the video below.
