Where are solar panels made? [Top 9 countries, 2026]
Wondering where solar panels are manufactured? We run through the nine countries that dominate solar panel production, from Canada to Taiwan.
The world's largest solar panel manufacturer is Tongwei Solar (TW-Solar), which was founded in China in 2009. China's control over the solar industry goes beyond just manufacturing and extends to the entire supply chain, including the production of almost 80% of the silicon needed for solar panels.
Like many manufactured goods, a single solar panel (or “module”) is made of multiple parts that are manufactured by separate companies located all over the world using raw materials from even more parts of the world.
The largest solar panel manufacturer in Vietnam is Trina Solar, a Chinese company founded in 1997, with a production capacity of 1GW. As of 2023, Vietnam had an installed solar capacity of just over 17GW, representing a remarkable growth from just 8MW in 2018.
By contrast, U.S.-based manufacturers produced 4.4 GW of solar PV modules. Imported modules came primarily from Asia, especially Malaysia, Vietnam, Thailand, and South Korea. China, whose imports are the subject of much political controversy, accounted for merely 1% of module imports to the U.S. at the end of 2020.
