Can Elon Musk bring solar power to developing countries?

From Europe to Australia, New York to California, solar power is becoming more of a common source for energy. The benefits of renewable energy are many but the drawback has always been financial; it’s simply too expensive to expect solar power to be the bulk provider of worldwide energy for now… or is it? If Tesla’s Elon Musk has his way, one of his other companies, Solar City, will be providing affordable solar power to everyone, everywhere.
