4 FAQs about Solar product support production

What is the solar PV supply chain?

The solar PV supply chain is one of the most geographically concentrated supply chains globally, as China dominates raw material mining and refining and manufactures over 90% of critical inputs such as polysilicon, ingots and wafers.

How can the solar PV industry support growing demand?

Annual investment levels need to double throughout the supply chain. Critical sectors such as polysilicon, ingots and wafers would attract the majority of investment to support growing demand. The solar PV industry could create 1 300 manufacturing jobs for each gigawatt of production capacity.

What are conversion factors in solar PV supply chain?

Conversion factors between segments in PV supply chain, stocks of modules, lead time for manufacturing investment by region and product, and job creation of the manufacturing by product are collected from the Special Report for Solar PV Global Supply Chain from IEA 4.

How has technology changed the solar PV supply chain?

Technological innovation throughout the solar PV supply chain has increased the conversion efficiency of solar cells, reduced material usage and improved energy efficiency per module. Since 2010, solar PV cells have become nearly 60% more efficient and generation costs have fallen almost 80%.
