With the announcement that it intends to build the world’s largest solar power plant, China is rapidly evolving into the world’s largest market for solar energy. And with heavy government backing, Chinese solar companies are quickly becoming global leaders.

By sucking the air out of energy prices and sapping private investment, the financial crisis submarined solar energy last fall. But a silver lining has emerged around the dark cloud that has blanketed the sector for so long.

Solar energy was given a boost last week after $18 billion in tax credits for clean energy were tacked on to the bailout bill to ease its passage through Congress.

Since then, however, concerns of oversupply have whacked solar stocks. This prompted Goldman Sachs (NYSE:GS) to downgrade several solar companies to a “sell”.

J. Cristoph Amberger says the current financial crisis will hurt investment in solar power. He recommends investors sell their positions while they still can.
