Despite the rapid decline in the cost of solar photovoltaic (PV) systems in the past five years, even recent academic research suggests that the cost of generating PV electricity remains too high for PV to make a meaningful contribution to the generation of grid electricity in developing...

The photovoltaic (PV) power industry has grown rapidly in recent years, and associated with that growth has been a decline in costs. There are indications that PV has already reached cost-parity with power off the grid in some markets and projections that it will attain such grid parity in many...
