Solar energy has come a long way since the first commercial silicon solar cell was purchased by the US in 1953.

In the 1970s, the oil crisis prompted a push for alternative energy, and the US allotted over $8 billion to solar research and development. However, the project was cancelled by President Reagan before it could make a significant impact.

Japan and Germany then stepped in and created a global market for solar technology. Germany's feed-in tariff program, which promised to pay power companies double the market price for renewable energy, made it a no-brainer for developers to build solar projects. As more panels were produced, the cost of generating electricity with solar continued to decrease, making it an unqualified success story.
