Sales of Solar Cells Take Off: Solar cell production has averaged 35% annual growth for the last five years with 2002 on the same track.  2001 saw 375 MW built, for a total of 1800 MW installed. "More than a million homes worldwide, mainly in villages in developing countries, now get their electricity from solar cells.. Solar cells currently cost around $3.50 per watt for crystalline cells, and $2 per watt for thin-film wafers, which are less efficient but can be integrated into building materials. Industry analysts note that between 1976 and 2000, each doubling of cumulative production resulted in a price drop of 20 percent. "  35% annual growth translates to cumulative doubling every 2.5 years, or halving costs every 8 years.  4:26:56 PM  permalink
