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.

30-year power warranty.

High Efficiency

Benefit from square mono cells and high-density

technology, the efficiency of Vertex can reach

up to 21%.

High Power

Maximum expected power : 500W+.

High Power Generation

Excellent temperature coefficient and low irradiation

performance.

5% - 30% of additional power generation brought by

the back side.

Integration of Innovative Technologies

MBB (Multi-Bus bar):

Multiple bus bars match large size wafer perfectly

High-density encapsulation technology:

Minimized space between cells to improve

module efficiency by 0.2-0.3%

The largest wafer size:

Largest silicon ingot technology from semiconductor industry

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.
