Global share of solar power in electricity mix 2023, by country

In 2023, Luxembourg was the leading country in solar energy penetration, with solar power accounting for almost 24 percent of the country's electricity mix that year. Malta followed with a share of solar of more than 20 percent. On average, the share of electricity generation from solar energy worldwide was roughly 5.5 percent in 2023. In comparison with the previous year, figures increased by almost one percentage point. 

Solar energy generation worldwide

In total, solar energy production reached 1.3 petawatt hours in 2022, increasing by some 30 percent when compared to the previous year. Solar energy production was the highest in China, which generated over 584 terawatt hours of solar power in 2023. The United States was the country with the second-highest solar energy production that year, with some 238 terawatt hours generated. 

China’s solar photovoltaic industry

Aside for being the largest solar energy producer worldwide, China accounts for the largest production of solar energy components. In 2022, the country was responsible for almost 78 percent of the world's solar photovoltaic module production. Most of the largest solar component manufacturers worldwide are based in China. For instance, photovoltaic company LONGi was the leading solar ingot and wafer manufacturer worldwide, reaching a production output of 122 gigawatts in 2023.
