Over the weekend, the New York Times noted that the solar power “craze” is partly responsible for Wall Street’s recent good times. The Times used the example of solar giant SolarCity, which has seen a sevenfold increase in its share price to $59.27 since it went public, but this could just be starters for the US solar industry. An international research team based at North Carolina State University has come up with a simple way to increase the efficiency of organic solar cells by more than 30 percent, leading to lower costs and a much bigger market.
That’s great news for companies like SolarCity. The company – another brainchild of Tesla creator Elon Musk – packages and installs solar systems, so it’s not subject to the kind of downward global pricing pressures that doomed US manufacturers like Solyndra.
In fact, down works good for SolarCity’s business model. Solar cells account for about half the cost of a fully installed and connected solar system, so a major drop in the cost of solar cells will have a significant impact on overall costs. That gives SolarCity and other solar packagers another opportunity to offer their systems at more competitive prices, and nudge conventional fuels out of the market.
