Fig. 4: Impact analyses of the energy consumption of photovoltaic panel supplies to the U.S.

Three cases in 2010, 2015, and 2020 are presented based on three types of crystalline silicon photovoltaic technologies: (a) single-crystalline silicon, (b) ribbon silicon, (c) multi-crystalline silicon. a–c represent the energy use for production across the entire supply chain for each trading partner. Seven scenarios in 2020, 2025, 2030, 2035, 2040, 2045, and 2050 are presented altogether in (d), with * indicating future scenarios.
