The current status of photovoltaic energy storage capacity development at home and abroad

Which countries have the most solar PV installed capacity in 2022?

In 2022, the most significant expansion in the solar PV market occurred in China, the US, and India, with increments of 86.1 GW, 17.8 GW, and 13.5 GW, respectively (IRENA, 2023). Fig. 2 shows the contribution of each continent in the world's solar PV installed capacity in 2018, followed by 2030 and 2050 based on IRENA’s REmap analysis.

What was the global PV production capacity in 2023?

Accessed March 21, 2024 ; EIA “Annual Energy Outlook 2023.” Accessed March 21, 2024. At the end of 2023, global PV manufacturing capacity was between 650 and 750 GW. 30%-40% of polysilicon, cell, and module manufacturing capacity came online in 2023. In 2023, global PV production was between 400 and 500 GW.

Where does solar PV development take place in the world?

Rapid solar PV development has occurred in other areas since 2013, particularly in China. In 2017, China became the largest solar PV market, outperforming Europe, with approximately 1/3 of the world’s installed capacity. The world's cumulative installed solar PV power capacity passed 1046 GW in 2022 (IRENA, 2023).

What is the global LCOE for solar PV technology?

The presented data indicates that the global weighted-average LCOE for solar PV technology was approximately 0.05 USD/kWh in 2022, projected to further decrease to a range of 0.014–0.05 USD/kWh by 2050. Currently, CSP technology has the highest LCOE at 0.118 USD/kWh among renewables.

Is solar energy a future energy resource?

The utilization of renewable energy as a future energy resource is drawing significant attention worldwide. The contribution of solar energy (including concentrating solar power (CSP) and solar photovoltaic (PV) power) to global electricity production, as one form of renewable energy sources, is generally still low, at 3.6%.

How much does solar PV cost?

3.2. Solar PV total installed costs Fig. 3 shows the variation of the global weighted-average total installed cost of solar PV projects since 2014, followed by 2050. It is seen that the global weighted-average total installed cost of solar PV projects reduced by about 67% from 2652 USD/kW in 2014 to 876 USD/kW in 2022.
