Countries With the Most Solar Power: Ranked

China has by far the most installed solar power capacity in the world, with over 600 gigawatts (GW) — more than the rest of the world combined. It is followed by the United States (roughly 180 GW), India (about 90 GW), Japan (around 85 GW), and Germany (about 82 GW).

Introduction

Solar power has become the fastest-growing source of electricity on the planet, with global installed capacity surging past 1,500 GW in the mid-2020s. Falling panel prices, government incentives, and climate commitments have driven a boom in deployment on every continent. But the growth is highly concentrated: a handful of countries account for the overwhelming majority of the world's solar generation.

This guide ranks the countries with the most installed solar photovoltaic capacity. It also explains why China sits in a league of its own — dominating not only the amount of solar it has installed at home but also the manufacturing of the panels that power the rest of the world.

Top Countries by Installed Solar Capacity

The Global Leaders

• China: Over 600 GW of installed solar capacity, more than the rest of the world combined. China adds well over 200 GW of new solar in a single year, an amount that once would have taken the entire world a decade to install.
• United States: Roughly 180 GW installed, the second-largest total. Growth has been driven by utility-scale solar farms in states like California, Texas, and Florida, supported by federal tax credits.
• India: About 90 GW and rising rapidly. India has set some of the world's most ambitious renewable targets and hosts vast solar parks such as Bhadla in Rajasthan, one of the largest solar installations on Earth.
• Japan: Around 85 GW. With limited land, Japan has pioneered rooftop solar and floating solar farms on reservoirs.

Europe and the Southern Hemisphere

• Germany: About 82 GW, remarkable for a country with relatively little sunshine. Germany's early "Energiewende" policy made it an solar pioneer, and it still leads Europe in total capacity.
• Brazil: Roughly 40 GW and climbing fast, driven by both large solar farms and a boom in distributed rooftop generation across its sun-rich interior.
• Australia: Around 35 GW, with one of the highest rates of rooftop solar per person in the world. More than a third of Australian homes have panels on the roof.
• Spain: About 30 GW, benefiting from abundant sunshine and large utility-scale projects. Spain is also a leader in concentrated solar power that uses mirrors to generate heat.

Together these eight countries account for the large majority of global solar capacity. The gap between first place and the rest is enormous: China's total dwarfs even the combined capacity of the United States, India, and Japan.

Why China Dominates Solar

China's lead is about far more than installed panels. The country manufactures the great majority of the world's solar components, controlling roughly 80% or more of the global supply chain for polysilicon, wafers, cells, and finished modules. This manufacturing dominance drove down panel prices worldwide, which in turn accelerated adoption everywhere — including in China itself.

Massive state investment, cheap financing, and vast tracts of sunny land in western provinces such as Xinjiang and Qinghai allowed China to build gigawatt-scale solar farms at a pace no other country can match. As a result, China now leads simultaneously in solar manufacturing, new annual installations, and total installed capacity — a rare triple lead in a strategic industry.

Quick Questions

Which country has the most solar power?

China has the most installed solar capacity by a wide margin, with over 600 GW — more than the United States, India, Japan, and Germany combined. It also installs more new solar every year than the rest of the world put together.

Does the United States or India have more solar?

The United States has more, with roughly 180 GW of installed capacity compared with India's approximately 90 GW. However, India is growing faster in percentage terms and has set aggressive targets to expand its solar fleet.

Why does Germany have so much solar despite limited sunshine?

Germany was an early mover, using generous feed-in tariffs in the 2000s and 2010s to reward homeowners and businesses for installing panels. That policy built a huge base of capacity long before sunnier countries caught up, and Germany still leads Europe in total installed solar.
