China ranks first with (205 GW).
According to the IEA's Renewables 2022 report, China has by far the world's biggest installed solar energy fleet, with 205 GW built in 2022.
In the same year, solar energy generated 223.8 terawatt hours (TWh) of power in the country.
Despite being the world's greatest emitter, the Chinese economy's massive energy demands can handle both the world's largest coal and renewable fleets.
Government subsidies boosted activity in the industry in the late 2010s, but commercial project subsidies are currently being taken out in favour of a competitive auction model.
The Huanghe Hydropower Hainan Solar Park (2.2 GW) in Qinghai province is China's largest single solar project.

The United States ranks 2nd with 76 GW.
In 2019, the United States has the world's second-largest installed solar capacity, totaling 76 GW and produced 93.1 TWh of power.
Solar installations in the United States are expected to reach over 419 GW over the next decade as the country ramps up its renewable energy initiatives and tries to totally decarbonize its electricity grid by 2035.
Utility-scale projects dominate the solar sector in the United States, with California, Texas, Florida, and Virginia among the most active states.
The renewable portfolio standards (RPS) law, which requires energy retailers to produce a percentage of power sourced from renewable sources, is a primary driver of development in the United States. Falling deployment costs and applicable tax subsidies have also fueled expansion in recent years.
Japan ranks third with 63.2 GW.
According to IEA data, Japan ranks third among nations with the biggest solar power capacity, with a fleet of 63.2 GW in 2019, generating 74.1 TWh of energy.
Alternative energy sources like as solar and other renewables have grown in popularity after the Fukushima nuclear accident in 2011, which caused the government to considerably reduce its nuclear energy efforts.
Japan has adopted feed-in-tariff (FiT) programmes to effectively incentivize the deployment of solar technology, although the solar PV industry is anticipated to decelerate significantly in the coming years.
According to the IEA, Japanese PV additions are likely to shrink beginning in 2022, owing to the phaseout of the generous FiT plan for large-scale projects and undersubscribed capacity in recent auctions.
Nonetheless, depending on government policy and cost reductions, installed solar power in Japan might reach 100 GW by 2025.
Germany ranks fourth with 49.2 GW.
Germany is Europe's solar deployment leader, with a national fleet of roughly 49.2 GW in 2019, providing 47.5 TWh of power.
Competitive auctions have helped the industry in recent years, and the German government has suggested raising its 2030 solar installation target to 100 GW as part of its goal of achieving a 65 percent renewables contribution in its energy mix by the end of the decade.
Small-scale, private installations are prevalent in Germany, with government support mechanisms such as reimbursement for surplus generation incentivizing them, while utility-scale projects are likely to rise in the coming years.
The 187-megawatt (MW) Weesow-Willmersdorf plant north of Berlin, created by German utility EnBW, is the country's biggest solar project to date.
India ranks fifth with 38 GW.
India has the world's fifth-largest installed solar capacity, with 38 GW built in 2019 and 54 TWh produced.
Over the next several decades, India's energy consumption is predicted to outpace that of any other area, and as the world's third-largest carbon emitter, policies are being devised to transition the country away from fossil fuels like coal and toward renewables.
Government plans include 450 GW of renewable energy capacity by 2030, with solar projected to play a key role.
Under current policy goals, the IEA forecasts solar to account for around 31% of India's energy mix by 2040, up from less than 4% now.
The agency attributes this turnaround to the "exceptional cost-competitiveness of solar" in India, which "out-competes current coal-fired electricity by 2030 even when combined with battery storage."
Nonetheless, transmission-grid constraints and land-acquisition problems will need to be overcome in the coming years to expedite the growth of India's solar power sector.
