The Lawrence Berkeley National Lab has released its “Tracking the Sun II: The Installed Cost of Photovoltaics in the US from 1998-2008” report. Among their findings is that the average cost of going solar in the US has declined by more than 30% between 1998 and 2008. They are crediting the government initiatives at the state and local level for the decrease in price and have also found that after a three year plateau, costs have decreased by 3.6% between 2007and 2008.
