Short answer, not in the short term. From the Green, Inc. blog of the NY Times:

The stimulus package, while welcome, may not be a quick fix for the struggling wind and solar industries, experts say.
“Unfortunately, the tight debt markets will still keep many projects from moving forward immediately.”
— Craig Mataczynski, R.E.S. Americas
The package is loaded with tax credit provisions that both industries have long sought — including a three-year extension of the production tax credit for wind, and an option of converting tax credits from both industries into direct cash. In theory, that means the federal government could end up footing the bill for 30 percent of the cost of a wind farm or solar array.
Despite the boost from the government, experts say that the financing markets are still so frozen that the stimulus provisions may not immediately restart the industries, which grew rapidly in the last few years but were forced to lay off workers and cut back projects after the banking crisis hit.
“Unfortunately, the tight debt markets will still keep many projects from moving forward immediately,” said Craig Mataczynski, president of Renewable Energy Systems Americas, a wind developer, in an e-mail message. “When the debt market thaws a little we could see a number of new projects move forward.”
Keith Martin, a lawyer with Chadbourne & Parke, said in an e-mail message that while the stimulus “can only help,” there are a few unknowns, such as how rapidly the Department of Energy can gear up a crucial loan guarantee program that would aid renewable energy projects — a matter on which the Department’s history is not promising.
