It's almost 4 years in the making now, and can produce 850MW.

The Guardian reported that China's remote, 27-square-kilometre solar farm tops an ever-expanding roll call of supersized symbols that underline China’s determination to transform itself from climate villain to green superpower.

"Built at a cost of about 6bn yuan (£721.3m) and in almost constant expansion since construction began in 2013, Longyangxia now has the capacity to produce a massive 850MW of power – enough to supply up to 200,000 households – and stands on the front line of a global photovoltaic revolution being spearheaded by a country that is also the world’s greatest polluter," it said.
