A lot of cross currents in the solar patch the past week; to reiterate I like the "sector" in terms of long term growth (US and China have yet to begin to scratch the surface of ultimate demand) but find investing in the sector a high risk game akin to gambling. Most of these stocks are populated by day trading types whose holding period is akin to... well, I suppose HAL9000. They are scary to short as well, because at any moment if oil pops the solar stocks can jump 15% in a session.

I called for a major purge in the group a few years back (Jan 3, 2008: The Long Term in Solar) as far too much capacity has come online and would prefer to see this space consolidated down to a handful of industry giants. Then it should become easier to invest in.

Speaking of glut, according to Digitimes, there is a potential that half of existing solar manufacturers might be gone by the end of 2010. That would actually be a good step for the long term in my eyes.

• As many as 50% of the more than 200 solar manufacturers, mired in red ink with current selling prices above US$2.00 per watt, may not survive, The Information Network stated.
• The market research firm recently noted massive inventory buildup and huge overcapacity were having a serious impact on the solar panel industry and manufacturers, and Dr. Robert Castellano, president of The Information Network has now pointed out that inventory is averaging 122 days in 2009 versus 71 days in 2008. Capacity utilization dropped to 27.9% in 2009 from 48.0% in 2008.

Those are some scary numbers. Capacity continues to increase because Chinese entrants continue to be born.

• A key reason is increased supply from China, which added an additional 1GW of capacity.
• The price per watt has now dropped to US$1.80 for polysilicon-based products, which is lower than the US$1.85 level The Information Network previously thought the industry would see at the end of 2009. By way of comparison, the average selling price in the third quarter of 2008 was US$4.05 per watt.

So naturally when a supply glut happens what do you do? Throw out the economics playbook - you build even more.

• The Information Network doesn't expect other industry players to back down from increased competition from China. Other makers are expected to increase their capacities despite the low utilization rates in order to reach economies of scale and better compete against the Chinese. The market research firm expects the industry to see a 25.7% capacity utilization rate and 133 days inventory in 2010.

This is the war to the bottom; many casualties will be taken.

Speaking of additional capacity ....

First Solar (FSLR) put on a large reversal yesterday after it was announced that the world's largest solar field would be located in China. But not to worry, the US shall be the leader in green energy jobs.
