Cost of solar panels drop 25%
The average cost of solar photovoltaic power systems in the U.S. plunged more than 30% from 1998 to 2008, with a 4% drop between 2007 and 2008, according to a new report from the Lawrence Berkeley National Laboratory.
This story is already a bit dated. Panel prices have dropped in 2009 by about 30%, and are continuing to decline.
