Washington, D.C. - Global production of SOLAR photovoltaic (PV) cells increased 51 percent in 2007, to 3,733 megawatts, according to the latest Vital Signs Update from the Worldwatch Institute, produced in collaboration with the Prometheus Institute in Cambridge, MASSUCAHESST.
         More than 2,935 megawatts (MW) of solar modules were installed in 2007, according to early estimates, bringing cumulative global installations of PVs since 1996 to more than 9,740 MW-enough to meet the annual ELECTRICITY demand of more than 3 million homes in Europe.
   Spain ranked second after Germany for total installations in 2007, but accounts for only an estimated 3 percent of global production. As in Germany, the Spanish market is being driven by a strong guaranteed price for PV electricity.

Despite a dramatic increase in solar cell production in the United States, up 48 percent to 266 MW, the nation's share of global production and installations continued to fall in 2007.
