Chile tests floating solar panels to power mine, save water

An island of solar panels floats in a pond at the Los Bronces mining plant, about 65 kilometers (approximately 40 miles) from Santiago, Chile, Thursday, March 14, 2019. The island of solar panels could give purpose to mine refuse in Chile by using them to generate clean energy and reduce water evaporation.(AP Photo / Esteban Felix)

The 1,200-square-foot array of solar panels was inaugurated Thursday by Chilean Mining Minister Baldo Prokurica. Officials said that if the test is successful, the $250,000 plant could be expanded to cover 40 hectares, or nearly 100 acres. (AP Photo/Esteban Felix)

Los Bronces is about 3,500 meters (11,500 feet) above sea level. In 2018, the mine produced 370,000 tons of fine copper and 2,421 tons of molybdenum. (AP Photo / Esteban Felix)

If the yearlong experiment works as planned, the solar panel island could be expanded and new ones could be installed at other mining ponds. Experts say there are approximately 800 such ponds in Chile. (AP Photo / Esteban Felix)

The array floats in the middle of a pond that is used to contain the refuse from mining, known as tailings, and it is expected that the island's shadow will lower the water temperature and reduce evaporation by 80 percent.
