Growth of photovoltaic floating plant.
When we think of solar panels or photovoltaic panels, the first thing that comes to mind are the typical installations that are on top of the roofs of houses or even the photovoltaic fields; but in recent years, a new modality that is floating solar panels is emerging. And what is this? Very simple, the installation of a photovoltaic field in the water.
These facilities are usually carried out on surfaces of artificial waters such as irrigation canals, reservoirs or even treatment plants.
One of the latest installations that has caught our attention has been Huainan, in China.
It is the largest floating photovoltaic plants in the world and is located in the old mining area that sank as a result of excessive activity.
The lake that there is now has been formed over the years with rain and thanks to the large reservoir have been installed a total of 166,000 photovoltaic panels that float along 13 islets and occupy an area of 140 hectares.
This type of aquatic solar fields has a number of very interesting advantages:
- The reduction of water evaporation that normally occurs in reservoirs or lakes.
- Save space for planting, that is, normally this type of photovoltaic fields are usually implanted in areas of land that can be used for the planting of any product, so if these installations of photovoltaic systems are transferred to the water they can be followed taking advantage of the fields for cultivation.
- Increase the efficiency of photovoltaic panels, thanks to the effect of cooling, getting them not to heat up so much.
One of the main drawbacks of the installation of these large equipment is that a large initial investment is needed, because the materials used are not the same as those used when installing a photovoltaic field on the ground, this is mainly due to to that the materials must be special to support the corrosion and in addition due to his little accessibility the maintenance also will suppose a greater cost.
Undoubtedly there are some countries that are more pioneers than others, this time the main countries that have started to take off in this modality have been the United Kingdom, Japan and China.
Another relevant fact is that Japan is home to 45 of the 70 largest floating photovoltaic plants in the world.
Finally, we would like to point out that Spain is currently interested in these plantations, and have managed to install one in the town of Lorca, Murcia, more specifically on the raft of Huerto Chico.
This solar park has 1480 photovoltaic panels and have a power of 90 Kw.
