ver the past decade, the title of the “largest solar farm in the world” has changed hands frequently. As the global demand for renewable energy surges, countries are racing to expand their solar capacity, pushing the limits of what was once thought possible.
In 2014, the Topaz Solar Farm in California held the title with a 550-megawatt (MW) facility. Just a year later, Solar Star, another California-based solar project, surpassed it with a capacity of 579 MW. By 2016, India took the lead with the Kamuthi Solar Power Project in Tamil Nadu, boasting 648 MW of capacity.
Then, in February 2017, China claimed the top spot with the Longyangxia Dam Solar Park, a massive solar installation with a staggering 850 MW of capacity.
Located in Qinghai province, China, the Longyangxia Dam Solar Park has seen rapid expansion. Satellite images captured by the Operational Land Imager (OLI) on Landsat 8 showcase its dramatic growth over just four years. By January 5, 2017, the solar panels covered an impressive 27 square kilometers (10 square miles). Reports from that time indicate that the site housed nearly 4 million solar panels.
This expansion aligns with China’s aggressive push into solar energy. In 2016 alone, China doubled its total installed solar capacity to reach 77 gigawatts (GW). This propelled the country far ahead of other leading solar energy producers such as Germany, Japan, and the United States, solidifying China’s position as the world’s largest solar power producer.
However, despite this rapid expansion, some other nations still generate more solar power per capita.
While Longyangxia Dam Solar Park held the title of the world’s largest solar farm in 2017, its reign was unlikely to last long. Reports indicated that a new project in China’s Ningxia region—with a planned capacity of 2,000 MW—would soon surpass it.
This continuous growth in solar energy infrastructure highlights the global shift toward renewable energy sources. As countries invest in larger and more efficient solar farms, the competition for the title of largest solar farm in the world will likely remain a temporary distinction.
The Longyangxia Dam Solar Park represents a significant milestone in the transition to renewable energy. With the rapid expansion of solar power worldwide, the future of clean energy looks increasingly bright. As new projects emerge, pushing the boundaries of scale and efficiency, solar power continues to play a crucial role in the fight against climate change.
