Not necessarily actually. It may, and would in the short run, increase
the production costs of solar units. That is what has happened over
the past couple of years as solar demand has moderately accelerated.
The high quality silicon needed for most types of solar panels has
been in short supply and the price of it has gone up dramatically.
Along with the cost of panels. As part of past jobs,  I used to
analyze the relative cost-effectivness of power plants, renewables and
end-use effficiency (aka dmand-side managment -- compact flueroescents
being an example of such). 15-20 years ago, it was clear that if the
cost of natural gas (the fuel of a majority of new and proposed power
plants) doubled, photovoltaics would be more cost-effective. But in
just the last five years natural gas has nearly tripled in price. yet,
solar is still not competitive -- without incentives. Why -- the
increased demand on soalr has increased the demand of high purity
silicon -- and its price has gone way up. 

Thus an immediate large scale- gov't induced renewables plan (see
adjacent post) where wind and solar saturations hit 20-60% of all
homes and businesses in 5 years) could cause solar PV panels  to
sky-rocket in price -- short run. 

But it would accelerate research on other PV methods (using lower
grade silicon, or gallium arsenide) or other solar technologies --
hydrogen conversion, solar heat turb ines, etc. long-run, prices could
hit  increased lows as massive research, spurred by very strong,
sustained and high price signals, began to payoff with new technologies.
