The cost of risk mitigation-Diversifying the global solar PV supply chain

In a recent issue of Nature, Helveston et al. estimate cost savings to users of photovoltaic modules arising from the concentration of manufacturing in China. However, concentration presents a supply chain risk, and there are plans to diversify this with domestic production. Are the resultant higher costs worth it?
