Global production of photovoltaic panels increased by 51% in 2007, according to the Worldwatch Institute. In the U.S., the overall share of the total global production fell, despite an increase of 48%. This points to the fact that photovoltaics are growing faster in other countries than in the United States.
Worldwatch Institute saw that the price of PV declined slightly in 2007. For more information on the study, visit www.worldwath.org/node/5449
