Based on improvements in cell efficiencies and production economies of scale, today’s manufacturing cost per watt can range from as low as US$0.82 to $1.05. With a continuous progression of cost reduction inherent in production, supply chain and module technologies, the reality of mainstream global grid parity is close. In fact, continuing cost declines in PV power production are enabling unsubsidised markets to grow in emerging economies and in meeting the peak power demands being amplified with the decommissioning of old, polluting power stations. In the US we see homeowners seizing the initiative, one rooftop at a time, to break free of the wired world.
