Solar Energy Statistics 2025

As we step into 2025, the solar energy landscape is more dynamic than ever, reflecting significant growth and technological advancements.

Here’s a snapshot of the current state of solar power:

Solar Energy Statistics

Global Installed Capacity

The world is set to add more than 5,500 gigawatts (GW) of new renewable energy capacity between 2024 and 2030, with solar photovoltaic (PV) accounting for a substantial portion of these additions. 

Solar Power Generation

In 2022, power generation from solar PV increased by a record 270 terawatt-hours (TWh), up by 26% from 2021. Solar PV accounted for 4.5% of total global electricity generation, marking its position as the third-largest renewable electricity technology behind hydropower and wind. 

U.S. Solar Market Growth

In the United States, solar power generation is projected to skyrocket by 75%, from 163 billion kilowatt-hours (kWh) in 2023 to an impressive 286 billion kWh by 2025.

Renewable Energy Expansion

In 2025, renewables-based electricity generation is set to overtake coal-fired generation. This milestone underscores the accelerating pace of the energy transition and reflects the growing reliance on renewable energy sources like solar, wind, and hydropower.

Technological Advancements

The global solar PV manufacturing capacity is expected to reach almost 1,000 GW in 2024, adequate to meet annual IEA Net Zero by 2050 demand of almost 650 GW in 2030. 

Solar Installations in the UK

Britain’s largest solar farm plan, Botley West in Oxfordshire, is set to install over two million solar panels by 2027, generating 840 megawatts (MW) of electricity and powering 330,000 homes. 

Key Takeaways:

• Grid Stability: The rapid expansion of solar installations necessitates advancements in grid infrastructure to maintain stability and accommodate the influx of renewable energy sources.
• Battery Storage: Integrating battery storage systems is becoming increasingly vital to store excess solar energy and ensure a reliable power supply during non-sunny periods.
• Environmental Impact: The shift towards solar energy significantly reduces greenhouse gas emissions, contributing to a cleaner and more sustainable environment.
• Energy Transitions: Businesses and governments worldwide are accelerating their energy transitions, investing in solar farms and other renewable projects to meet climate goals.
• Average Cost: The average cost of solar panel installations continues to decline, making solar power more accessible to a broader audience.

In conclusion, 2025 marks a pivotal year for solar energy, with unprecedented growth in installed capacity and technological advancements. As solar power becomes increasingly integral to global energy strategies, continued investment and innovation are essential to harness its full potential.
