Munich-based Phoenix Solar AG, a German photovoltaic system installer, has committed $615 million (450 million Euros) to purchasing Solyndra's cylindrical solar cells as a core part of its future rooftop installation business. Why? "We see significant cost-savings," says chief technology officer Manfred Bächler. "We simply do not need any supporting structures or ballasts or roof penetrations," because, unlike traditional flat solar panels, the new round kind don't need any help to keep grounded when the wind blows.
In addition, the ability of the solar cylinders to collect direct, diffuse and sunlight reflected from the rooftop—as well as the ability to lay panels of them horizontal to the roof itself means more electricity can be made from a given rooftop. Further, the solar cylinders keep cooler overall, which enhances the performance of the system, Bächler says.

The U.S. electric grid is so old and outdated it can't handle the influx of wind power and other intermittent renewable resources. Integrating such sources requires adapting a system that is finely tuned to balance the amount of electricity being used with the amount of electricity being generated with fickle winds.
But there is an even more pressing problem, according to this article in the New York Times: the grid isn't big enough. The wind tends to blow strongest in places, such as North and South Dakota, that are far from where people live and use electricity. And no one wants to spend the millions of dollars it would take to put in a new transmission line (not to mention the legal headache of getting all those rights of way).
