Satellite images from NASA show the sprawling growth of Longyangxia Dam Solar Park, the largest solar farm in the world.The solar farm holds 4 million panels and has an 850-megawatt capacity.

In China’s Qinghai Province, 4 million solar panels are visible from space, soaking up sunlight. The panels are part of the largest solar farm in the world, Longyangxia Dam Solar Park, which NASA has chronicled in satellite images.

The complex has grown rapidly since its creation in 2013 when it started as a cluster of panels, as seen in an early NASA image.

, which pushed the country ahead of other leading producers of solar energy, according to a release from NASA. By Jan. 5, its panels spanned across 10 square miles in Qinghai province.

Currently, –enough to power about 140,000 American homes, according to Live Science.

and halt the growth of its annual greenhouse gas emissions by 2030 under the Paris Climate Agreement, Business Insider reported. Last year, the nation invested $103 billion in renewable energy.

“for the next few years, or foreven longer,” Hong Kong Polytechnic University renewable energy professor Yang Hongxing told the South China Morning Post. “The low cost of building photovoltaic modules (solar panels) in China is the country’s main advantage. Many modules in the U.S. and Europe are made in China.”

A project planned for China’s Ningxia region will likely bump Longyangxia to the second-largest solar park in the world, NASA also said. The proposed park will have a capacity of 2,000 megawatts when it is completed.
