Floating solar projects are popping up in all corners of the world, from Japan, the UK, Brazil, the U.S. and Australia.

There are a number of benefits to floating solar plants, aka "floatovoltaics." Compared to mounted panels, floating systems are naturally cooled by the bodies of water they sit on, therefore boosting power production efficiency. Many floating PV developers point out that the floatovoltaics shade the water, which reduces water evaporation and slow algae blooms.
“The efficiencies are what motivated us to look at this,” Rajesh Nellore, the chief executive of Infratech Industries, told the New York Times.
The Sydney-based company erected a floating solar system in Jamestown, South Australia that claims to generate 57 percent more energy than rooftop panels.
The plant floats on a wastewater facility in Jamestown and is the first part of a larger system that will cover five basins, the company says on its website. The system consists of raft supporting standard photovoltaic panels, which are specially coated to prevent corrosion, due to their close proximity to water.
Another plus of floating arrays is how it makes use of unused space. In the UK, a 6.3 megawatt floating solar project consisting of 23,000 solar panels sits on Walton-on-Thames' Queen Elizabeth II reservoir, an area that isn't used for any other purpose, The Guardian reported. The £6 million (about $8 million) project will help power local water treatment plants that provide clean drinking water to London and south-east England’s 10 million residents.
At roughly the size of eight soccer stadiums, the Thames Water floating solar array will briefly hold the title of world's largest floating solar facility before Japan’s mega-solar farm finishes in 2018, which will have a capacity of 13.7 megawatts. The New York Times noted that if everything goes as planned in the next two years, the 50,904 panels that will float atop the Yamakura Dam reservoir in Japan will generate an estimated 16,170 megawatt hours annually or enough electricity to power almost 5,000 homes.
The company behind Japan's massive solar plant, Kyocera TCL Solar, started construction in January this year and explained why floatovoltaics are ideal.
"With the decrease in tracts of land suitable for utility-scale solar power plants in Japan due to the rapid implementation of solar power, Kyocera TCL Solar has been developing floating solar power plants since 2014, which utilize Japan’s abundant water surfaces of reservoirs for agricultural and flood-control purposes," the company said in a press release.
Solar is also an increasingly attractive option for regions or countries that are going through drought. With Brazil's historic drought drying up its hydroelectric plants, the South American country is turning to solar power to diversify its energy mix to stave off a potential power crisis.
As EcoWatch reported last year, below-average rainfall in recent years have depleted the country's reservoirs, thus gutting the country's formerly plentiful supply of hydropower, which supplies more than three-quarters of Brazil's electricity, the U.S. Energy Information Administration states.
The nation announced last year it would commence pilot tests of a 350 megawatt floating solar farm located atop the Balbina hydroelectric plant in the Amazon.
“We are adding technological innovation, more transmission lines, diversifying our energy generation source, introducing solar energy in a more vigorous manner and combining solar energy with hydroelectric energy,” Mines and Energy Minister Eduardo Braga said last year.
According to PV Magazine, Brazil switched on the first 10 megawatt stage of its floating Ballina plant in March.
Another advantage of floating solar systems is that they can be hidden from public view, which is a factor that led the California nonprofit Sonoma Clean Power to pursue the technology, the New York Times reported.
“Sonoma County boasts some of the most beautiful rolling hills, and people don’t want to see them covered by solar panels,” Rebecca Simonson, a senior power analyst for the renewable energy developer, told the publication.
The Times reported that the company has signed purchasing agreements for floating solar arrays to be built on six treated water ponds in the county. The solar panels, Simonson said, would not be visible from the road.

Cabin fever is often associated with being cooped up on a rainy weekend or stuck inside during a winter blizzard.
In reality, though, it can actually occur anytime you feel isolated or disconnected from the outside world.
What is cabin fever?<p>In popular expressions, cabin fever is used to explain feeling bored or listless because you've been stuck inside for a few hours or days.

What can help you cope with cabin fever?<p>Because cabin fever isn't a recognized psychological condition, there's no standard "treatment." However, mental health professionals do recognize that the symptoms are very real.</p><p>The coping mechanism that works best for you will have a lot to do with your personal situation and the reason you're secluded in the first place.</p><p>Finding meaningful ways to engage your brain and occupy your time can help alleviate the distress and irritability that cabin fever brings.</p><p>The following ideas are a good place to start.</p>
When to get help<p>Cabin fever is often a fleeting feeling. You may feel irritable or frustrated for a few hours, but having a virtual chat with a friend or finding a task to distract your mind may help erase the frustrations you felt earlier.</p><p>Sometimes, however, the feelings may grow stronger, and no coping mechanisms may be able to successfully help you eliminate your feelings of isolation, sadness, or depression.</p><p>What's more, if your time indoors is prolonged by outside forces, like weather or extended shelter-in-place orders from your local government, feelings of <a href="https://www.healthline.com/health/anxiety" target="_blank">anxiety</a> and fear are valid.</p><p>In fact, anxiety may be at the root of some cabin fever symptoms. This may make symptoms worse.</p><p>If you feel that your symptoms are getting worse, consider reaching out to a mental health professional who can help you understand what you're experiencing. Together, you can identify ways to overcome the feelings and anxiety.</p><p>Of course, if you're in isolation or practicing social distancing, you'll need to look for alternative means for seeing a mental health expert.</p><p>Telehealth options may be available to connect you with your therapist if you already have one. If you don't, reach out to your doctor for recommendations about mental health specialists who can connect with you online.</p><p>If you don't want to talk to a therapist, <a href="https://www.healthline.com/health/depression/top-iphone-android-apps" target="_blank">smartphone apps for depression</a> may provide a complementary option for addressing your cabin fever symptoms.</p>
The bottom line<p>Isolation isn't a natural state for many people. We are, for the most part, social animals. We enjoy each other's company. That's what can make staying at home for extended periods of time difficult.</p><p>However, whether you're sheltering at home to avoid dangerous weather conditions or heeding the guidelines to help minimize the spread of a disease, staying at home is often an important thing we must do for ourselves and our communities.</p><p>If and when it's necessary, finding ways to engage your brain and occupy your time may help bat back cabin fever and the feelings of isolation and restlessness that often accompany it.</p>
