China is home to the world’s largest solar farm, which is so immense, it is visible from space. With around four million solar panels, Longyangxia Dam Solar Park has a capacity of 850 megawatts (MW) – pushing the country closer to its ambitious renewable energy goals. NASA recently shared satellite images of the solar park as seen from space – and they are admittedly impressive.

The award for world’s largest solar farm has switched hands rapidly in the last few years. In 2014, California’s 550 MW Topaz Solar Farm was the biggest, but a year later the state’s 579 MW Solar Star claimed victory. The next year, 2016, saw India’s 648 MW Kamuthi Solar Power Project topple the throne, only to be ousted by the Longyangxia Dam Solar Park this year.

NASA Earth Observatory’s satellite images of the Chinese solar park reveal immense growth over four years. By early January of this year, the Longyangxia Dam Solar Park, which is in the high desert of the Qinghai province, covered 10 square miles. China became the largest producer of solar power in the world after the country’s total installed capacity increased to around 77 gigawatts in 2016, even though other countries like the United States and Germany produce more solar energy per person.

Rapid progress has marked China’s renewable energy industry in recent years. According to Climate Central, drawing on preliminary 2016 data released by Greenpeace’s Energydesk, the country “installed the equivalent of one and a half soccer fields of solar panels every hour.” Such advancement means China could hit their 2020 renewable energy targets as soon as 2018.

NASA doesn’t expect the Longyangxia Dam Solar Park to retain the crown for long. The Mohammed bin Rashid al Maktoum Solar Park in Dubai is still growing – phase 3 will add 800 megawatts to the farm. And another solar farm planned for China’s Ningxia region in the northwest is slated to have a capacity of 2,000 MW.
