6 FAQs about [The gap between domestic and foreign solar cells]
What factors influence the cost of diffused solar PV manufacturing supply chains?
The factors that influence the cost of diffused solar PV manufacturing supply chains relative to concentrated ones in China and Southeast Asia are first labor cost and then interest burden. Here the interest burden represents a potential increase in the cost of capital for investment.
Why is international cooperation important for solar PV Manufacturing?
Consequently, states must cooperate to coordinate finance, subsidies, incentives, and trade barriers for solar PV manufacturing. This international cooperation is essential to diversify supply chains so that it will minimize increased costs, leverage scale, and increase innovation and resilience while reducing market uncertainty. Introduction
Can solar PV reduce supply chain dependencies?
Given the undergoing energy transition, any supply chain concentrated to this degree brings vulnerabilities from potential shocks. Like-minded countries consequently look to reduce the risks from such concentration. National governments have taken efforts to spur domestic manufacturing of solar PV to reduce supply chain dependencies.
What is the cost difference between concentrated and diffuse solar PV supply chains?
The cost difference (final module cost) between concentrated and diffuse solar PV supply chains is sensitive to labor costs, interest burden, and electricity cost. Costs are final module cost.
Are solar photovoltaics a cost-effective supply chain?
Absent subsidies, fully integrating domestic supply chains of solar photovoltaics will come at substantial cost to some economies (Figure 3). China and Southeast Asia remain the most cost competitive reflecting the current concentration of solar PV manufacturing in these regions.
Which country has the fastest growth in solar manufacturing capacity?
Source: Bruegel and Rhodium based on the Ember Electricity Dashboard. While Europe leads the US in deployment, growth in solar manufacturing capacity is far faster in the US. Investments in the PV manufacturing supply chain were largely on par in the EU and US in 2021 and the first half of 2022 (Figure 3).
