Solar Basics: What is a floating solar array?

welcome to solar basics I'm Kelsey

floating solar or floating photovoltaics is a solar array that floats upon a body
of water the solar panels are placed on a buoyant structure to keep them above
the water's surface and are usually located on relatively calmer bodies of
water such as ponds lakes and man-made reservoirs one of the greatest
advantages of floating solar is that it doesn't occupy land that could be used
for other purposes and eliminates the need for vegetation and tree removal the
water has a cooling effect on the equipment which is good for efficiency
as high temperatures decrease solar panel performance these installations do
come with some disadvantages though they're more costly than land based
solutions due to specialized equipment being needed
although costs are expected to drop with further developments and technology also
the majority of floating solar arrays are larger in scale making them suitable
for communities utility companies and municipalities but not ideal for
individual households despite these challenges floating solar is on the rise
it's worldwide operational capacity was only 10 megawatts in late 2014 but that
figure increased 100 times reaching 1.1 gigawatts by September 2018 floating
solar has blown up in Asia but is still in its infancy in the United States
Sealand Tera built its largest us floating installation yet in 2019 a 4.4
megawatt project on a New Jersey water storage apartment floating solar is an
exciting new prospect that further expands the possibilities for solar
power in the United States more on solar mounting read our story online and stay
