Solar power: Darkest before dawn

Solar power: Darkest before dawn  finds that underlying PV costs are likely to continue to drop as manufacturing capacity doubles over the next three to five years. Indeed, the cost of a typical commercial system could fall 40 percent by 2015 and an additional 30 percent by 2020, permitting companies to capture attractive margins while vigorously installing new capacity.

The research suggests that the overall solar market will continue to grow—even though subsidies are expected to dry up. This growth, over the next 20 years, will stem largely from demand based on viable stand-alone economics in five customer segments: off-grid, residential and commercial in areas with good and moderate sun conditions, isolated grids, peak capacity in growth markets, and new large-scale power plants.
