Technical FAQs 4

What will PV module prices be in 2024 to 2030?

Figure 4 presents PV module prices in various countries under global and national scenarios from 2024 to 2030. In the 2030 global scenario, PV module prices are projected to be 0.14 USD/W in the United States, 0.61CNY/W in China, 0.09 EUR/W in the EU, and 23.97 JPY/W in Japan.

How can R&D help reduce PV module cost?

R&D, both public and private, was a key driver of module cost reduction historically and can be valuable going forward in improving module efficiency and reducing materials use. Improvements to module efficiency in particular would help cut the per-watt cost of all cost components of PV modules (as well as PV systems).

What causes photovoltaics cost decline?

We model technology improvement to identify causes of photovoltaics (PV) cost decline. Improvements to module efficiency and materials costs were important. Since 2001, increasing plant size enabled economies of scale to reduce costs. Market-stimulating policies were responsible for a large share of PV's cost decline.

How do market-stimulating policies affect the cost of PV modules?

Market-stimulating policies have played a central role in driving down the costs of PV modules, with private R&D, economies of scale, and learning-by-doing together contributing an estimated 60% of the cost decline in PV modules between 1980 and 2012.
