Photovoltaic energy storage foreign trade knowledge

Why is international trade important for PV cells?

Through the interaction of spatial patterns of PV cells international trade flow, the associations among regions have been strengthened and the development opportunities of PV industry have been expanded. This will also intensify the level of competition.

Why is the global solar PV product trade important?

The global solar PV product trade plays an important role in facilitating PV product production and utilization and in mitigating climate change. Traded solar cells and modules in 2017 could generate 2325.25 TWh of electricity over their 30-year lifetimes.

What is the spatial structure of PV cells international trade?

Nodes (countries and regions) and routes (trade flows) are two major metrics for the spatial structure of the PV cells international trade. Demand and supply of PV cells take place in each individual node. Consequently, the interactions amongst nodes are responsible for the formation of routes.

Does solar PV have a trade pattern in East Asia?

Yang et al. (2017) displayed changes in solar PV’s core-periphery hierarchical trade patterns in East Asia. Based on previous results, Guan et al. (2020) proposed functional trade patterns, the optimal trade patterns measured and determined by network motifs, to estimate the potential PV trade flows effectively.

Why are global PV trade activities growing?

Meanwhile, on account of the PV industry's uneven resource distribution and inconsistent production capacity across regions, as well as the necessity to cope with turbulences in energy markets, global PV trade activities have also experienced tremendous growth in recent years (Algieri et al. 2011; Guan et al. 2016; Guan and An 2017).

What is the global PV trade based on?

The data on global PV trade used in this paper comes from the BACI-CEPII 2 Database, covering 251 global economies from 1996 to 2019. According to the division of the PV industry, the upstream is composed of crystalline silicon raw materials and the preparation of silicon rods and silicon wafers.
