Putting solar panels on water is a great idea–but will it float?
Although U.S. adoption has been slow, some recent deals may turn the tide. A typical installation consists of solar panels on pontoons tethered to the bottom of a reservoir or retention pond—considered easier to utilize than lakes. Floating or underwater cables carry direct current to an inverter on shore where it is converted to alternating current and sent to the local grid. Engineers must consider multiple factors: systems have to withstand high winds and waves, panels must be resistant to corrosion and anchors have to last for 25 years or more.
