World Sales of Solar Cells Jump 32 Percent
"World production of solar cells—which convert sunlight directly into electricity—soared to 742 megawatts (MW) in 2003, a jump of 32 percent in just one year. With solar cell production growing by 27 percent annually over the past five years, cumulative world production now stands at 3,145 MW, enough to meet the electricity needs of more than a million homes. This extraordinary growth is driven to some degree by improvements in materials and technology, but primarily by market introduction programs and government incentives."
