Global energy structure and PV development trends
Source: IRENA Roadmap to 2050
According to IRENA:
Photovoltaic power will lead the
global energy revolution. Global solar
capacity will reach 8.5 TW by 2050.

LCOE Trend
The LCOE for solar PV is already competitive
now compared to all fossil fuel generation
sources and will be fully competitive in a few
years.
The global weighted average
LCOE of utility-scale PV
plants is estimated to have
fallen by 77% between 2010
and 2018.

Size (” / mm)
At present, the variety of wafer sizes in the photovoltaic industry leads to difficulty on module selection for customers.
The 210mm will be the ultimate size for the photovoltaic industry in the next 5 – 10 years.
