As of 2016, there were 60 solar panel farms in operation worldwide. It would take 10 solar farms to power every home in California, 142,000 to power the entire world. Remember, when the automobile was introduced, not everyone immediately transitioned, they still rode their horses and buggies for quite a while. It takes time, but in the next 5 years I have no doubt that solar technology will be recognized as the most viable energy source available. It is and will be a main source of power and empowerment to the nearly 8 billion humans who inhabit this planet.
