🛠️ The majority of solar panel manufacturers are based in China
China produces 86% of the world’s solar panels each year, according to Germany’s Fraunhofer Institute for Solar Energy Systems.
In comparison, Europe and North America each produce around 2%.
It therefore makes sense that six of the world's seven largest solar manufacturers are also based in China.
🏭 The largest solar panel manufacturer is TW-Solar, followed by JA Solar
Tongwei Solar (TW-Solar) is the largest solar panel manufacturer in the world.
TW-Solar shipped a whopping 38.1GW of solar modules in 2022, doubling Trina Solar's shipments and achieving an annual revenue of USD $20.57 billion (£16.2 billion).
The company employs over 50,000 staff around the globe and is the world's largest in-house polycrystalline silicon producer. It also plans to double its annual production capacity of 80GWp to 150GWp by 2025.
💷 TW-Solar is the only solar panel company on the Fortune Global 500 list
In August 2023, Tongwei Group made history as the first solar PV company on the Fortune Global 500 list.
It's still the only solar company on the global list, as of March 2024.
🍁 Canadian Solar is the only company outside of China to make the list
The sixth largest solar manufacturer in terms of shipments is Canadian Solar Inc. – the only solar PV module manufacturer on this list with headquarters based outside of China.
With over 20,000 employees in at least 30 countries, Canadian Solar operates large manufacturing facilities in both Canada and China, as well as Indonesia, Vietnam and Brazil.
Solar power is currently the world’s third largest renewable electricity technology after hydropower and wind (International Energy Agency, 2024), and it's ultimately powered by solar panel manufacturers.
From Asia to North America and everywhere in between, these manufacturers aren't just driving technological innovation but also shaping the future of clean energy worldwide
This article will explore the achievements and contributions of the top seven industry giants in the solar photovoltaic (PV) world.
What are the world’s seven largest solar manufacturers?
The National Renewable Energy Laboratory’s Spring 2023 Solar Industry Update Report sets out the details of the world’s largest solar panel manufacturers.
We've outlined them below, in ascending order, based on the manufacturers' number of solar shipments in 2022.
These shipments are measured in gigawatt-peak (GWp), which is a unit that tells us the peak power output of a solar PV device under standard test conditions. One gigawatt (GW) is equal to 1 billion watts (W), or 1 million kilowatts (kW).
7. Trina Solar
