I'm living in Tucson, Arizona the past 12 years, and there's certainly a lot of houses with solar panels... But there's also a lot of dust in the air because... well... this is the Southwest Desert, and any wind over 4-or-5 MPH will carry the dirt with ease... So, I'd imagine solar panels from Southern California to the High Plains Texas Desert will have concerns with dirty panels lowering efficiency...
It will fail just like it did in the 70's, the only difference between panels of today and the 70's is cost of manufacturing, their output is almost the same per square foot. There is a wind farm (Ocotillo wind farm) that it seems like every other month they have to shut them down, blade throw, fire, blade flexing to much and striking the tower and collapsing. Each time they all go off line until the investigation to the failure is determined, there is rarely a time when the wind is in the ideal conditions to use them, it's either not enough, or to much wind.
