Getting Solar on 100 Million American Rooftops #solaranalytics #pv

Farrell says that the “installed cost of solar has fallen 10% per year since 2006 and grid electricity prices have averaged a 2% annual increase in the last decade.” In his projections, he uses 7 percent annual decline for solar costs and 2 percent for electricity increases, which seems conservative but reasonable. Obviously either of those rates could change, but almost everything I’ve read and heard predicts rising electricity rates; the rate of solar cost decline is somewhat harder to predict. As a technophile, my money is on the cost of solar falling faster than expected.
