Global Solar Hits 2 Terawatts: Record 585–600 GW Installed in 2024
The world installed approximately 585–600 GW of new solar PV in 2024, a 30–33% increase over 2023 and the largest annual addition of any energy technology in history. This pushed cumulative global solar capacity past 2 terawatts (2,000 GW) for the first time. Multiple independent monitoring bodies — IEA, IRENA, IEA-PVPS, Ember, and SolarPower Europe — all confirm this as a record-breaking year for solar deployment. Solar generation also exceeded 10% of global electricity supply in 2024 for the first time.
Findings
- Global solar PV installations reached approximately 585–600 GW in 2024, up 30–33% from 2023 — the largest single-year addition ever recorded for any energy technology.
- Total worldwide solar capacity crossed 2 terawatts (2,000 GW) for the first time, a milestone no other power source has reached in so short a time frame.
- Solar generation surpassed 10% of global electricity supply in 2024 for the first time, adding a record 474 TWh of generation year-over-year.
- Minor numeric spread across sources (452–602 GW) reflects methodology differences — grid-connection timing versus physical installation, off-grid inclusion — not factual disagreement about the record-breaking trend.
