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.

Difficult Times Ahead for Solar Inverter Suppliers As Supply Exceeds Demand

IMS Market Research - Press
According to a new report from IMS Research, inverter capacity will be ramped past 30 GW this year and inverter production may exceed actual demand by more than 2 GW in Q4’10 leading to large inventory build. This effect reverses the earlier inverter shortage seen in the first half of 2010 and is set to impact the industry as it heads for a major slowdown in demand in Q1.
