Finding PV's Next Big Cost Reductions

Comment on Renewable Energy News Article

Cost is one of the biggest barriers to bringing solar to scale. Tremendous strides have been made to date -- module prices have come down 50-70% in the past two years alone. Where are the next cost reductions going to come from?
(...) even without a radical breakthrough, there are plenty of cost reduction opportunities in today's technology. Both balance of systems (BOS) and silicon raw material supply offer promising paths to lower costs.(...) [N]ear-term reductions of more than 50% by simply scaling and implementing current best-practices. That alone would reduce total BOS costs to around $0.60 to $0.90/W for large rooftop or ground-mounted installations.
