Solar speedbump: Mountain or Mole Hill?

Last week saw the release of a report predicting that solar would see a serious speedbump in 2010, as the current shortage of polysilicon eases and solar cells flood the market. The report predicts difficulty for both thin-film players and the chrystalline silicon makers that depend on polysilicon as a key ingredient in their products. For green marketers in solar, this could mean that the window of opportunity is much smaller than previously thought.

This report looks at the supply side of the equation and sees doom for manufacture profits and gloom for their investors. I wonder, however, how much the report thoroughly investigated the demand side of the equation. There are a number of things that should increase solar demand in the coming years and may partially or substantially offset any increase in supply:

Improved storage capacity--one of the biggest technology bottlenecks to the adoption of all renewals has been battery and storage efficiency. That said, millions are being invested in battery companies right now, including A123, Lion Cells and Seeo, which will help in terms of power storage in applications like electric cars, solar and wind. If the storage gets better, then the demand and ROI will go up significantly.
Speaking of electric cars--one of the biggest contradictions in my mind is the use of an electric car charged on coal-generated electricity. What's the answer? Charging it with renewables. The use of solar combined with good battery technology and electric cars just makes too much sense. It also doesn't require substantial infrastructure overhauls like changing the types and locations of fueling stations. A solar implementation on a house, office building or even carports, would be a huge advantage.
Government support--next January will definitely see a change in the political climate for solar and other renewables. All three major presidential candidates have stated that they believe in renewable sources of energy and will commit more investment in areas like solar. This includes direct investment in R&D and other areas, but also better federal tax incentives and rebates. These rebates will allow solar companies to protect some of their margins as the supply of solar increases.

There is no doubt that solar is riding high right now because of the perfect storm of high demand, low supply and large sums of investment. It also makes sense that the market wil mature eventually and it will be a bit more commoditized. But to predict it is going to get there in two years is a bit silly IMHO, since we have just begun to scratch the surface of building integrated photovoltaics and other solar applications beyond the panels you see today.
