The use of solar panels is something more and more common and that is seen in more countries as the years progress. Solar energy is one of the most popular ways to produce clean energy, since it uses an unlimited and natural resource such as sunlight. In fact, it is very common to see some of these structures in the middle of the road when we are doing a trip. However, do you know that there are solar panel farms that float in the middle of the water?
These structures are not as popular as the typical terrains where solar panels are found on land, but they may even offer better performance.
Higher performance than conventional solar farms
Solar panels can be installed in the middle of a lake, a reservoir or even the sea. It is a good alternative in the event that there is no land on the ground large and firm enough to install this system.
Although the sea can also be used to place them, the ideal options are lakes or reservoirs, since they are freshwater. In addition, in them the water is always calm (not like in the sea) and the risk of erosion by salinity is eliminated.
The performance of floating solar panels can be even higher than that of conventional solar farms. This is due to the temperature reached by the modules. Solar panels reduce their performance as the temperature increases, but, if they are placed in water, this helps them to regulate their temperature and offer energy in a more efficient way.
To install these floating structures, floats are used that are connected to each other by cables that provide greater strength.
Clean and efficient energy
Therefore, its installation does not require the use of heavy machinery but, on the contrary, a much simpler and easier to handle structure. It also has a lower impact on the environment since by saving the use of different vehicles and machinery, there is no noise pollution or emissions from the use of said vehicles.
Many countries use these floating structures to produce electricity from sunlight. In our country, the Arroyo de San Serván plant (Badajoz) stands out, where there are about 1,500 solar panels floating throughout an area that occupies about 6,000 square meters.
A couple of months ago, Singapore also turned to the use of this technology by installing more than 120,000 solar panels across 45 hectares of land. With them, electricity is supplied to five water treatment plants in the country.
However, China is home to the world’s largest floating solar farm, which has the capacity to supply electricity to 15,000 households in Anhui province. In total, there are up to 166,000 solar panels supplying power.
