What is the global area of PV solar panels in 2022?

In the temporal analysis of global PV solar panels for 2019–2022, the global area of PV solar panels for each year 2019–2022 was first counted. In 2019 the global area of PV was 3831.6 km 2, and in 2022 the area of PV grows to 6469.8 km 2, the growth is 2638.2 km 2. The overall growth rate of PV solar panel area is more than 60%.

What are the classification results of PV solar panels?

Moreover, the classification results of the PV solar panels align closely with the actual characteristics of solar panel installations and PV arrays, accurately delineating the clear contours of solar panels and the gaps between contiguous solar panels.

What is the global installed capacity of photovoltaics in 2022?

According to the data provided by the International Energy Agency (IEA), the global new installed capacity of photovoltaics in 2022 was 133 GW, while the cumulative installed capacity reached 843.0 GW. In 2023, global installed renewable energy capacity additions are expected to increase by 50% compared to 2022.

What is the theoretical potential for PV power generation?

Theoretical potential for PV power generation is best characterized by the long-term distribution of solar resource, in other words, the ‘amount of fuel’ available for PV electricity generation at a given loca-tion.

What policy changes impacted solar PV growth in 2021 – 2022?

However, the following policy and target changes in 2021–2022 had an impact on solar PV growth. In June 2022, China released its 14th Five-Year Plan, which set a goal of 33% renewable electricity generation by 2025 (up from 29% in 2021), including an 18% target for wind and solar technologies .

What are the spatial distribution characteristics of PV solar panels in 2022?

From the spatial distribution characteristics of PV solar panels in 2022 (Fig. 7a), global PV is concentrated in the middle and low latitudes, and there is little PV distribution in high latitudes. Besides, PV solar panels are mostly distributed in densely populated areas of the world except Africa.
