4 FAQs about The latest photovoltaic panel capacity expansion and transformation plan

How long has solar PV been deployed?

The pace of solar PV deployment in recent years has been unprecedented. While it took nearly 70 years – from the first commercialisation of solar cells in 1954 – to reach the first 1,000 GW (1 TW) of capacity, the second TW was added in just two years.

How much solar capacity did the world add in 2025?

In the first six months of 2025, the world added 380 GW of new solar capacity — 64% higher than during the same period in 2024, when 232 GW were installed. In 2024, it took until September for global solar capacity additions to surpass 350 GW, while in 2025, the milestone was reached in June.

How big is solar PV in 2024?

Global solar PV installations set another record in 2024, reaching 597 GW – a 33% increase over 2023, and 148 GW more the previous year (Fig. 1). Although the annual growth rate slowed compared to the exceptional 85% surge in 2023, it was still substantial enough to reinforce solar energy's leading dominance on global renewable energy expansion.

How much solar power will California generate in 2024?

In 2024, solar represented 13.7% of net summer capacity and 6.9% of annual generation. (36 GWac) will continue in 2025 (39 GWac) and remain at similar levels in 2026 (36 GWac). In 2024, 24 states and territories generated more than 5% of their electricity from solar, with California leading the way at 32.4%.
