Solar PV continues to dominate global renewables growth, though at a slower rate

Recent policy changes are expected to affect the pace at which solar PV capacity is added annually through the end of this decade. Even so, low costs, faster permitting and broad social acceptance are set to continue to drive the accelerating adoption of solar PV. As a result, capacity is set to more than double between 2025 and 2030 compared with the 2019 to 2024 period.

A growing share of variable renewable sources such as solar also comes with challenges. Curtailment levels and instances of negative electricity prices have been increasing in many markets. A rapid increase in power system flexibility and grid investment is necessary to integrate future growth securely and cost-effectively.
