In India:

“The Indian state of Gujarat has built the world’s largest solar photovoltaic power plant, a field of solar panels the size of Lower Manhattan. After only 14 months of preparation, they’ve just switched it on, adding 600 MW of power to the grid. That’s enough to power a medium-sized city’s worth of homes.”
