Sungrow Floating Power Plant

The world’s largest floating solar power plant is now online in China. Built by Sungrow, a supplier of PV inverter systems, the 40MW plant is now afloat in water four to 10 meters deep, and successfully linked to Huainan, China’s grid. The placement was chosen in large part because the area was previously the location of coal mining operations; and, as a result, the water there is now mineralized and mostly useless. The lake itself was only formed after years of mining operations, the surrounding land collapsed and created a cavity that was filled with rainwater.

Floating solar plants are advantageous because they put otherwise useless water and land to good use, and the water naturally cools the system and the ambient temperatures, improving generation and limiting long-term damage from heat.
