What is the national photovoltaic power generation in 2021?

In 2021, the national photovoltaic power generation will reach 325.9 billion kWh, an increase of 64.8 billion kWh compared to 2020, a year-on-year increase of 24.82%, accounting for about 4% of the country’s total annual power generation. The national photovoltaic power generation and growth rate from 2016 to 2021 are shown in Figure 2 [ 8 ].

What is photovoltaic power generation?

Photovoltaic power generation is one of the most important and basic sources of renewable energy. Photovoltaic power generation is a technology that directly converts light energy into electrical energy by utilizing the photovoltaic effect of the semiconductor interface. The main components are controllers, inverters and solar panels (components).

What is solar photovoltaic (PV) & how does it work?

As a result of this industrial revolution, solar photovoltaic (PV) systems have drawn much attention as a power generation source for varying applications, including the main utility-grid power supply. There has been tremendous growth in both on- and off-grid solar PV installations in the last few years.

How much solar power will be generated each year?

This figure increased to 66.2 TWh in 2016 and 118.2 TWh in 2017 and accounted for 1.1% and 1.8% of the total power generated, respectively. In this study, we assume the annual solar PV power generation will not be less than 2% of the total power generation, and the cap will increase by 0.2% annually.

How much solar power will be generated by 2050?

Solar PV power generation capacity is projected to reach 7000 TWh by 2050 . PV power generation is highly dependent on uncontrolled weather and environmental conditions, such as module temperature, solar irradiance, wind speed, wind pressure and direction, atmospheric temperature, humidity, etc.

When will the solar PV power development target for 2050 be achieved?

The solar PV power development target for 2050 will be achieved in 2048, two years ahead of the schedule. The development trend will be maintained before 2040, but the a big vibration of the installed capacity appears after 2041. The target of 1300 GW will be achieved in 2048, with an average new increased capacity of 108 GW from 2041 to 2048.
