A common criticism of solar power is that ground-mounted arrays take land out of use for the duration of a system\u2019s lifespan. But rooftops and land aren\u2019t the only places solar can be installed \u2014 developers are now looking to water too.<\/p>\n

Floating solar arrays are a racking technology used more often outside of the United States, in countries like Japan that boast many man-made bodies of water suited for \u201cfloatovoltaics<\/a>.\u201d In 2017, the U.S. had only seven floating arrays, but they\u2019re now starting to gain momentum stateside, said Stetson Tchividjian, business development manager for D3Energy, a floating solar EPC and affiliate of floating rack manufacturer Ciel & Terre.<\/p>\n

\u201cThe last 12 months have been night and day,\u201d he said. \u201cWe\u2019ve seen a lot of traction. Projects all over the place are in negotiations and engineering phases. It\u2019s definitely picking up steam, to say the least.\u201d<\/p>\n

The National Renewable Energy Laboratory released a report<\/a> in December 2018 that found floating solar arrays could account for 10% of the nation’s energy needs if they were installed on just a quarter of the man-made lakes and ponds in the United States. \u201cMany of these eligible bodies of water are in water-stressed areas with high land acquisition costs and high electricity prices,\u201d the report reads. And it\u2019s much easier to get permitting to put solar on the water than land, Tchividjian said.<\/p>\n

Floating solar shares the same principles as traditional roof- or ground-mounted systems. The system is built in a modular fashion \u2014 the floats that hold the panels are assembled block by block on land, then rowed out into the water. It\u2019s anchored using traditional ground-mount means, like ballasts or helical piles, that are driven into or set upon the lake bed. Tchividjian said assembly and installation is straightforward, with the most important consideration being engineering. Floating solar systems need to work with rising and falling water levels, and in certain cases even rest in dry retention ponds. The wiring needs to be safely led from the array to land. The finished array can be accessed by boat.<\/p>\n

The upfront costs of installing floatovoltaics are higher than ground-mount systems, but the payoff can be a system that offers low O&M thanks to no landscaping requirements. Floating solar also benefits the water where it resides, providing shading to reduce evaporation and curb algae counts. While power production on individual sites might not be as high as ground-mounts, floating solar arrays are viable options for cities with little land or roof space.<\/p>\n

\u201cWe keep eating up all these hundreds of acres of land that\u2019s valuable, usually healthy farmland and things like that, for solar,\u201d Tchividjian said. \u201cYou fast-forward 10, 15 years from now, you\u2019re going to start having some pushback. This is high-quality land that we keep using and I think floating [solar] answers that question of being able to continue to go green and use bodies of water in spaces that we have no other use for.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"
