The installation is one of the barriers for the total triumph of the solar panels. China wants to fix it with “stickers”

by

Betting on the installation of solar panels is something that seems key in the Ride for decarbonization in which we are immersed. And the country that has proposed to dominate the production and sale Of these panels is China. Multitude of companies have risen to the ship of the production of photovoltaic panels, so much that a Price war that is not favoring To the industry itself. And in that wild competitiveness, betting on innovation is key. As a result, one of these companies has recently shown its new products. The objective: fill all the roofs of these flexible solar panels. The keys. That company is Polyshine Solar, a Shanghai -based company that has been focusing solar panels that can boast something very unique: being light. This is not easy, but at the opening of the World Smart Energy Week, held in Tokyo, the Chinese company has shown His new flexible panels. These panels stand out for three key features: their simple installation with an adhesive layer that allows a fast deployment, its flexibility to adapt to various surfaces and a weight 70% lower than conventional glass panels. Behind those happy lords are the panels “Paradigma change”. Although what attracts attention is the weight of the panel and a flexion radius that the company has affirmed that it is 0.5 meters, which define As a “paradigm change” in the energy transition is the ease of application of the panel. Thanks to this simplification of the installation by reducing the action to a process of “paste and generating electricity”, Polyshine Solar considers that it will be something that democratizes access to renewables. Characteristics. On the margin, these modules are available in several versions with powers that vary between 505 W and 535 W. The energy conversion efficiency is between 19 and 20.1% and the panels have dimensions of 2,246 x 1,185 x 2.5 mm and a weight of 7.5 kg. This combination of weight, flexibility and the ease of placing them, “eliminate installation barriers on curved surfaces or structures with low load capacity, without additional reconditioning costs,” Comment The company. Apart from the adhesive surface, you can also hang and hold with straps. Guarantees. Polyshine states that, after 25 years, their panels will maintain at least 84.8% of their output power. They have IP68 protection against water and dust thanks to an EVA encapsulated and can operate in a temperature range between -40 ° and 85 ° Celsius. For a few years, the company’s light panels have been placed In areas such as acoustic barriers for roads within cities, resisting vehicle vibrations. And challenges. Now, as well Comment The company, getting a reduction in weight is not easy and is something that is at odds with efficiency. Each 0.1% increase in lightness and flexibility represents a challenge because it is something that can affect energy production. To face this, these years have opted for highly transparent materials, and the fruits are modules that generate 2% more energy in the same conditions as similar products. They do not specify what these similar products are, but they do comment that, although 2% look little, when 1,000 m² of their panels are installed, there are additional 5,000 kWh per year. Beyond corporate discourse, this progress reflects a change of focus on industry: they not only seek Improve energy efficiencybut optimize weight and ease of installation for Accelerate the adoption of renewables.

If today we can see a planetary alignment it is because the entire orbit solar system in the same plane. And not by chance

by

Tonight we will have a chance to see one of the astronomical events of the year, The great planetary alignment: Seven planets (all the major planets of our solar system) will be visible in the night sky. To understand why this phenomenon and discover what it is and what is not, it is convenient to keep in mind some details about the dynamics of our solar system and its history. That is, the very story of the planets that accompany ours in the orbit around the sun. Ecliptic. The name of the phenomenon itself, Planetary alignmentindicates that it is an event in which the planets are arranged in a row. However, we must bear in mind that when we talk about this we do not talk about the planets forming a precise row in their orbital displacements as in textbooks, nothing is further from reality. The alignment of the planets refers to the fact that, at some point, these appear aligned in the night sky, that is, it is an apparent alignment from our terrestrial point of view that occurs around an imaginary line that crosses the night sky. This imaginary line is the ecliptic, but in reality it is much more than a line marked by the planets. And it is that most of the objects of our solar system move through it. Even the stars seem to move following the path that this brand. From the album to the planets. Strictly, the ecliptic It is defined as the imaginary plane that contains the orbit of the earth around the Sun. That is why this imaginary line is marked by the movement of our star in a daily transit by the celestial vault. However, due to the fact that the orbits of planets, satellites and asteroids of our solar system orbit in different planes, the ecliptic and its surroundings become the projection in the vault of the sky of an album, the disk formed by all this infinity of orbits of objects that rotate at different distances already varied speeds but practically always in similar planes. It is no accident that almost all the subject of our solar system is presented on this album. To understand the reason, we have to go behind in time, to the formation of our solar system, to the era in which around our star there were no planets, but a Protoplanetary disc. Return to the origins. The origin of the solar system is in a cloud of gas and matter that ended up concentrating. In doing so, Due to the conservation of angular momentumthe cloud was taking one more disk appearance, turning at the same time on itself. The center of that cloud continued to concentrate, until it reached critical mass and density for the formation of a star, the sun. The rest of the album was orbiting around the sun, now like a ringthe so -called protoplanetary disk. The dust also began to concentrate on different points of this album also due to gravity. Progressive clashes were giving rise to increasingly large concentrations, dust that became increasingly large rocks until planets and asteroids were formed, all still turning in the same direction in which millions of years ago revolved the protoplanetary disc and, before, the original cloud. The movement of the Earth. There is another factor that contributes to all objects from heaven to seem to scroll in unison and it is the fact that the Earth’s rotation axis is aligned with the axis of rotation of its orbital movement. This is more or less common, although there are exceptions such as Uranus. If we were on this planet, we would see night after night that the stars distant to us move from this to west normally, but the solar ecliptic would move very differently, a more exaggerated version of the solar movement given in the polar circles, with a seasonal cycle of days and nights. This implies that in summer, the ecliptic plane would be a circle in the celestial vault, something very different from what we perceive from Earth.

There is a spiral structure surrounding the solar system

by

Thousands of kilometers from our planet there are all kinds of mysteries to discover. Some we end up deciphering them, like that Strange television signal It takes years to solve, but others remain with that halo of singularity. In this group there is everything from Low intensity magnetarsuntil those radio bursts that we detect from time to time. And then there is Oort’s cloud, a fascinating region that has just revealed something surprising. A spiral in the confines. The edge of the solar system has long been a little explored, obvious border, since it is a vast and enigmatic territory full of ice cream that orbit at extreme distances. Over there, Oort’s clouda region that extends up to 100,000 astronomical units (UA) of the Sun, has been considered a simple sphere of debris Cosmic, but a recent computational study has placed it on the front page. The reason? An unexpected and fascinating structure has been revealed: A spiral structure similar to that of a miniature galaxy. The finding, directed by astronomer David Nesvorný of the Southwest Research Institute and Posted in The Astrophysical Journal After its diffusion on the ARXIV predimussion server, it reveals that the gravitational force of the Milky Way has shaped the internal Oort cloud in a spiral structure of 15,000 A diameter. This spiral, which has endured since the beginning of the solar system, Challenge the previous conceptions about the morphology of Oort’s own cloud and could redefine our understanding of the evolution of transneptunian objects. The composition of the Oort cloud. As far as we know, Oort’s cloud has traditionally divided into two regions. The external Oort cloud, located beyond 10,000 UA, is a spheroid of icy bodies that are weakly linked to the sun and suffers frequent gravitational disturbances of nearby stars. From this region come most of the long period comets, those who travel through the solar system in elliptical trajectories after being diverted by gravitational interactions. On the other hand, the internal Oort cloud is between 1,000 and 10,000 UA, and so far it was believed that it had a more stable and disk -shaped structure. Due to its proximity to the sun, the objects in this area They are more strongly linked to their gravity and are less susceptible to external star disturbances. However, the new computational models have revealed that their shape is not a uniform disc, but a spiral structure with twisted arms and an inclined disk about 30 degrees with respect to the ecliptic plane. The influence of the Milky Way. Apparently, the key to this unexpected morphology lies in the interaction of the internal Oort cloud with The so -called “galactic tide”a gravitational phenomenon generated by the Milky Way. This force, exerted by the gravitational attraction of the galactic center, nearby stars and possible black holes, especially affects the most distant regions of the solar system. He Model developed by Nesvorný And his team was prosecuted in NASA’s Pleiades Superordinateusing data on the formation of the solar system 4.6 billion years ago. During the simulation, the scientists introduced the gravitational influence of the Sun, the impact of galactic tide and interaction with the Milky Way. Results? It was found that The spiral was formed in the first hundred years after the creation of the Solar System and has remained stable since then, even resisting the nearby step of stars in the last millennia. Implications and challenges of finding. As the researchers say, one of the most surprising aspects of the study is that the spiral is not a temporary effect or a recent disturbance, but a permanent structure within the internal Oort cloud. Comparison with previous research suggests that this form has been present in multiple previous simulations, although it had not been identified so far. However, and this is underlined at work, confirming this structure through direct observations is little less than a monumental challenge. Reasons? The enormous distance and low luminosity of objects Oort’s cloud causes even the most advanced telescopes to be unable to detect them directly. In fact, most of the evidence of the Oort cloud comes from the study of long period comets, which limits the possibilities of characterizing its internal structure with precision. And despite these difficulties, scientists consider that this finding is A crucial step to understand the history of the Solar System. The spiral structure of the internal Oort cloud could provide clues about how the icy bodies in the confines of the solar system were formed and evolved, in addition to helping to understand the impact of the Milky Way in our cosmic neighborhood. A new horizon in exploration. No doubt, the discovery of this spiral structure in the internal Oort cloud challenges the traditional conception of the already enigmatic edge of the solar system, showing that The severity of the Milky Way has played a crucial role in its formation and evolution. The finding also reinforces the need to develop new methods of observation and space missions dedicated to exploring the regions farthest from the solar system. If you want also, it enhances the idea we already had, that Oort’s cloud is still an unexplored bordera cosmic file that retains the primitive history of the Solar System. As the researchers indicate, their study could reveal key information on the origin of comets, the dynamics of transneptunian bodies and the interaction of our planetary system with their galactic environment. Next to nothing. Image | DOLANH, NASA /ESA AND A. FEILD /SPACE TERESCOPE SCIENCE INSTITUTE In Xataka | For five years we have tried to decipher a television signal that came from the sky.

Emirates financed a study to know if it can cause rain in the desert with solar farms. The answer is yes

by

As water It becomes a more precious resource than oila group of scientists has analyzed if solar farms can have an even more beneficial effect than generating energy with sunlight: making it rain in the desert, offering the communities most affected by drought water and renewable energy at the same time . Climate engineering against drought. Given the drama of its waning water resources, the United Arab Emirates government financed a study published by German researchers in Earth System Dynamics. The researchers proposed to create artificial heat islands by installing large black surfaces (ideally, solar panel farms) to enhance precipitation in arid areas. A promising result. The scientists simulated the impact of these surfaces with advanced models and obtained surprising results. A heat island of 20 km² induces an increase in rains 571,616 m³ a day. This could be translated into water supplies for about 31,000 people. Only with an area of ​​20 km². But the interesting thing about study is not its quantitative results, but the possibility of implementing these surfaces taking advantage of existing infrastructure, such as photovoltaic solar panels. This solution would not only address water scarcity but also contribute to renewable energy production. How it works. That a farm of solar panels can induce rain is not a very intuitive concept, but it is something that He has been studying for a while, particularly in the Sahara. These facilities, by absorbing heat with their dark panels, could create ascending currents that, under the right conditions, would trigger rain storms. When these farms exceed a certain size (about 15 km²), the heat absorbed by the panels, in contrast to the most reflective sand, significantly increases the convection currents necessary for cloud formation. Areas where we know is viable. For this process to work, a source of atmospheric humidity is needed. The models showed that the wet winds of great height from the Persian Gulf are enough, to the joy of Emirates. The researchers also identified other areas of the world where it could work, such as Namibia and the Peninsula of Baja California in Mexico. Some limitations. The initiative requires darker surfaces than those commonly produced by solar panel manufacturers. Some panels are even reflective to improve your thermal performance. However, the Construction of increasingly large solar farmsespecially in China, they open the door to try the idea in the real world. It won’t be simple, of course. The implementation of gigantic heat islands raises logistic, but also ecological and social challenges. For example, how would these surfaces affect local biodiversity? What would be the visual and social impact on nearby communities? You need more research and pilot tests to discover it. The case of Emirates. The United Arab Emirates government, which financed the study, is facing the shortage of two ways, mainly: desalination and sowing of clouds. The program of Cloud sowing through airplanes Plan about 300 missions every year, but like desalination, it is an expensive method with limitations. In this context, large solar farm surfaces are a promising alternative.

It was inaugurated in 2014 as the largest solar thermal energy plant in the world. Will close after setting fire to birds

by

The huge Ivanpah thermosolar energy plant, opened in 2014 in the Mojave desert, will close after just 11 years of operation. An accelerated end for its history of technical, economic and environmental problems. Context. The thermal concentration energy, once considered one of the most avant -garde technologies for clean electricity generation, is not going through its best moment. Especially in Nevada, where Crescent Dunes fiasco was already very popular. The concentration thermoso use thousands of mirrors, or “heliosteats”, which follow the trajectory of the sun to concentrate its light on central towers. In these towers, extreme heat is used to heat water and produce steam, which drives turbines connected to electric generators. The Ivanpah case. The Ivanpah plant was built with an investment of 1.6 billion dollars in loans from the United States Department of Energy and long -term contracts for important electrical companies. It was the world’s largest solar thermal energy Until the inauguration of Port Augusta In Australia. 11 years after its inauguration, the huge thermosolar has begun to close by not fulfilling its initial expectations. The lack of profitability condemned her. A succession of failures and complaints from environmental groups for their impact on wildlife accelerated their end. A complex technology. One of the main problems has been the difficulty of maintaining mirrors aligned precisely. Technology, which requires an exact monitoring of the sun, has proven unstable and unreliable in practice, says a CNN report. The maintenance of the complex mechanisms and the management of the turbines in turn generate high operating costs, which has made concentration thermosar loses competitiveness compared to other renewable technologies, especially photovoltaic solar, whose prices have collapsed. A Bird Incinerate Machine. Criticisms are not limited to technical aspects. The Ivanpah plant has been questioned for years for its environmental impact, especially in the wildlife of the desert. Environmental groups denounce the irreparable damage in the habitat of species such as desert turtle. But also The death of birds that are incinerated by intense rays concentrated by mirrors. A second Crescent dunes. The case of Crescent Dunes, also occurred in Nevada, reinforces this image of failure of the thermosolar energy. This project, which was intended to be one of the milestones in energy innovation and storage through molten salts, ended up becoming a multimillionaire waste. Developed By the Spanish group ACSpromised continuous production of electricity, even during the hours without light, thanks to the thermal storage in salts. In practice, Crescent Dunes never managed to deliver the amount of promised energy and ended up breaking due to engineering and management problems. In the shadow of the photovoltaic. In short, the rapid drop in photovoltaic technology and its lower impact on wildlife have obsolete concentration thermos. While solar panels have gained efficiency and reducing their installation and maintenance costs, thermosolar plants have lagged behind in terms of competitiveness, which has led to investors and electrical companies reconsidering their bets in this type of projects.

The owner of a Tesla Model and has filled his roof of solar panels to load “up to 100 km”. It is not a good idea

by

He Solar car It’s like gold for the electric car. There, all wishes will be fulfilled: we will load our cars free of charge. End of the bonds of electric and oil forever. But we are so far from getting something like the gold appears in our lives. Different companies have proposed to experiment with the solar car and even sell their own models. Toyota, with the PRIusit filled the roof of it so that its plates would help the electrical components of the car. Mercedes, in his EQXX visionhe has played with the same idea. And, despite everything, from Sttutgart to Silverstone, a trip in which they toured more than 1,200 kilometersthey barely managed to extend the autonomy of the vehicle in less than 50 kilometers. But the Marketing From a solar car is very far. In the PRIus He contributed little. The Mercedes is a prototype designed to look for the limits of efficiency, both in aerodynamics and in chemistry of its batteries and consumption of its engines, so it is not too representative either. The 3.57 kWh recovered by the solar panels yielded much more in a vehicle of these characteristics than in a street car. Sono Zion, one of the most advanced projects, He ended up canceling. Those responsible for Lightyear, who said they were able to travel for free 70 kilometers daily with their solar car, have also ended by Lower the blind. In fact, since the vehicle was announced in 2019, its managers did not stop lowering expectations and, with them, the number of kilometers per year that the car could travel thanks to its solar panels. But all this has been no impediment to the owner of a Tesla Model and that ensures in Reddit having made your electric SUV a much more efficient vehicle thanks to some solar panels distributed along the ceiling. Figures that, of course, you have to take with tweezers. Putting it in quarantine As he has counted in a thread of Redditthis owner of a tesla model and ensures that he has designed a system of Foldable solar panels that allow you to load every day between 30 and 100 kilometers a day. In the presentation of his project, the user explains that the panels are folding and installed on the roof baca. He assures that in this first version, the panels stand out about 27 centimeters from the ceiling of the vehicle but that, in a new version in which he is working, he will reduce the height to about 15 centimeters, improve the flush and create a carbon fiber support To lighten the set. In total, the Tesla Model and can carry in the future, always according to the user, 4,000 W packaged On the roof, which once deployed can recover part of solar energy, transform it into electricity and recharge the car while it is parked. But many doubts arise here. First, he assures that He is working So that the solar energy is transformed into electric and goes directly to the car battery so, we understand, for now the energy is stored in a battery that subsequently recharges the vehicle. The other great doubt that arises is about the true efficiency of the whole. In 2019Toyota created a prototype of the PRIus that filled the entire roof, the rear window and the hood of the solar panel car. A surface that generated 860 W. With them, Toyota said he could travel some 45 extra kilometersbut they were based on the Japanese homologation cycle, much more lax than Europeans. In the case of Tesla Model and, the weight of the panels touches the maximum of 75 kg that in the United States can move on the ceiling, so it will irremediably affect consumption. First of all, those 75 kg of weight, which is more or less like going with one more person in the car. And, much more critical, for the impact on automobile aerodynamics, which would be very damaged. The creator says that he has not calculated the latter but believes that consumption worsens at 10%. All this has led some Work reviewers To affirm that the car can barely travel a little more than 40 kilometers under real circulation conditions. That without entering into the impact that the solar panels have on the dynamics of the vehicle and the march comfort, because it must be difficult to ignore the generated noise.

The biggest problem of Perovskita’s solar panels was its durability. China has just resolved it

by

The University of Beijing has just presented the most forceful advance of Perovskita cells in terms of durability, so far the greatest weak point of technology that promises to conquer solar panels. The news. A team of researchers has designed a Perovskita cell with a 24%efficiency, similar to that of the best silicon solar panels, than maintains 99% of its performance after 1,100 hours of operation at extreme temperatures. The context. Perovskita cells are The most promising technology to generate solar energy at low cost. Perovskitas have a crystalline structure that absorbs sunlight in a very efficient waybut unlike silicon cells, they can be manufactured through simple processes, with cheaper materials, and in flexible films. There are already commercial solar panels of Perovskita and have begun to be installed on a large scale, especially in complicated lands of Chinabut their least stability and durability prevents them from competing with silicon in other facilities, even when they are manufactured in tandem with the semiconductor to improve their performance. The problem. One of the key components of Perovskita cells, the formamidinium and lead iodide (FAPBI₃), is difficult to stabilize at room temperature and tend to degrade when it is exposed to sunlight for long periods. Which, for a solar panel, is … inopportune. FAPBI₃ degradation causes Perovskita solar cells to lose efficiency rapidly (they convert less amount of light into electricity) and are not viable to compete with silicon panels, which last 30 years. The solution. To overcome this obstacle, a laboratory from the University of Beijing has invented A new “intercalation-decalation” technique of iodinewhich consists of inserting iodine atoms into the structure of the FAPBI₃ to help better organize its components, and then eliminate the excess iodine during the heating process. The key is to facilitate the formation of lead and iodine blocks, whose atoms are joined by sharing corners in the structure of Perovskita. By favoring this configuration, the mobility of the ions is reduced that, otherwise, would contribute to the degradation of the material over time. Iodine acts as a stabilizer that improves the internal cohesion of the cell. The results. This method allowed researchers to obtain a high quality Perovskita movie, without waste that may compromise their performance. The cells that developed have an energy conversion efficiency of 24%: almost a quarter of the solar energy that affects them is transformed into electricity. But the most important thing is that they maintained 99% of their initial performance after operating for more than 1,100 hours at about 85 ° C, which is a very encouraging indicative of its durability and potential long -term use. As for lead. Lead concerns its toxicity, but today it is an essential component in the Perovskita formula: it contributes significantly to its ability to absorb light and turn it into electricity, so that commercially viable cells contain lead. However, solutions are also being investigated To eliminate it. Goodbye to defects. In addition to the one at hand, other laboratories are explored complementary solutions to eliminate defects, such as the integration of molybdenum disulfide layers (MOS₂) In the structure of the cells, which act as physical and chemical barriers, blocking the migration of those defective ions that can deteriorate performance. Both the technique of iodine and that of the MOS₂ point to the same: achieve a pure and stable perovskita that can work optimally and lasting. And convert the “great promise” of solar panels into a commercial reality. Image | Huansun In Xataka | In 2009, Perovskita’s solar panels wasted 97% of energy. Now they are ready to conquer the industry

Floating solar energy seemed all advantages. Until someone has occurred to him if it is

by

Earth is no longer the limit for solar energy. From The Acts of India until The Swiss Alps reservoirsgoing through more and more swamps in the Iberian Peninsula. Floating solar panels begin to cover all types of bodies of water with advantages that go beyond the generation of electricity, such as stop water evaporation in the areas most whipped by drought. The other effects of floating solar energy. Something we have less studied is how floating solar panels affect the ecosystem of some bodies of water, particularly small ponds and lagoons. A Recent Study of Cornell University It has analyzed the environmental consequences of covering these smaller bodies of water with floating solar energy and the conclusion is unexpected: they can significantly increase the emission of greenhouse gases of the organisms that inhabit the pond. The experiment. To carry out your research, scientists They installed photovoltaic panels on three experimental ponds In the Experimental Cornell Pond Facity. In total, they covered 70% of their surface. On the other hand, they left ponds exposed as control groups for the experiment. In this way, they managed to observe the changes and the evolution of the ponds in which they had installed floating solar energy by comparing them directly with other similar ponds without panels. The results. Although it was thought that floating solar energy has an environmental impact less than other energy sources, the results showed that it can generate counterproductive effects. Specifically, the researchers registered a significant increase in methane concentrations and carbon dioxide dissolved in the water, which raised greenhouse gas emissions of semi -covered ponds almost 27% compared to the unbreaking ponds Solar In addition, they observed a considerable decrease in the availability of dissolved oxygen, which can affect aquatic life and alter ecological processes such as decomposition and microbial activity. The conclusion. Although part of the gases were more slowly released due to the lower amount of water exposed to the sun, the largest concentration in the form of bubbles ended up increasing the total amount of emissions. These findings are especially relevant in the context of the energy transition, since many floating solar energy facilities are carried out in small lakes and ponds without taking into account how they affect the ecosystem. Here is the complicated part. If we compare the greenhouse gas emission trace per kilowatt generated time, floating solar energy remains more favorable than fossil fuel -based technologies. But the study shows that we still do not know very well how these rapid changes in the energy industry are affecting certain ecosystems. You have to continue investigating.

A Spanish startup has found a way to put solar panels in less than three hours: with a container

by

Installing and disassembling a solar panel seems arduous work that requires a lot of time, and in part it is so. However, a Spanish startup has arrived to reduce that time in less than three hours. Short. The photovoltaic solar generator company Nomad Solar Energy has launched A set of photovoltaic solar panels connected inside a container, which can be easily deployed with folding support and wheels that fit the ground. Thanks to its assembly “Plug & Play”, This system can be installed in any environment and, in case of extreme climatic conditions, protect within a container. The product, known as Nomad Energy Box, has achieved 15 million euros of Tilt Capital Partners financing for its international expansion and the development of new products. Location. The set of solar panels, which unfolds like an accordion, It has been designed to be versatile and functional in a wide variety of environments. Its ability to deploy quickly makes it ideal for emergency situations or areas with limited access to electrical infrastructure. So it can be installed in humanitarian, military, construction, remote camps, islands out of network or mining sites. In addition, its robust design and easy transport make it an attractive option for regions with extreme climatic conditions or complicated terrain. Available in two versions. Nomad Energy Box is available at 42.78 KWP and 106.72 kWP, both with High Efficiency Solar Panels and Huawei investors. In addition, they have CSC certification (Container Safety Convention) to guarantee the quality and safety of the container, ensuring their resistance to transport and storage in extreme conditions. Within the system there are three types of models. The first is the network connection, the standard installation that requires the investor to be always connected to the network. Then, the batteries that complement the system with energy storage for later consumption during the night or on cloudy days. Finally, the Total Island mode, that is, without connection to the network that allows the interconnection of several units to increase the available power. Not to stretch. Solar panels are progressing towards new forms, integrating into everyday objects like jackets, umbrellas or even Parasols for cars. There are also portable photovoltaic cells that you can carry with you for its size. For its part, a new study in Japan has achieved that a photovoltaic cell can be extended without cracking, as well as An investigation in Australia where we can see solar panel candles. The opening of the possibilities of solar energy in different environments is only the beginning of a constant technology.

France has thousands of kilometers of unused train tracks. So you are covering them with solar panels

by

Solar panels and wind turbines have placed us in a complicated decision: aesthetics or generating electricity? Beyond Impact on living beings of the environment in which these renewable projects are installed, it is undeniable that They have a huge visual impact. That’s why, New transparent solar panels for windows or hide them on roads They sound like a great idea. In Switzerland they have developed a project for Place solar panels on the train tracksand now France has copied the idea. Invisible panels. With the name of ‘Solveig Project’, the French rail operator SNCF It has developed, through its Arep subsidiary, a project to create a solar plant that can be deployed on the roads that the company controls. They explode about 32,000 kilometers of lines, so, if the project is successful, the potential is huge. The idea is simple, but ingenious: take advantage of the rails to install solar panels, while batteries and investors are stored in modular containers. For now, Solveig is a pilot project that has started with the installation of eight solar panels at the Achères Technical Center, where they will be tested for six months. Facilities. Having a storage solution such as containers, which include investors and batteries, it is possible for the company to transport these assets as far as it is needed. It also facilitates their installation. As Comment the Director of Innovation of AREP to PV Magazine, the development of a photovoltaic panel transport system through ISO containersas well as its installation on the roads, “it facilitates both the deployment of the panels and the reversibility of the installation.” The operation does not require a complex installation, since a mechanical arm is responsible for downloading the panels, which are subsequently fixed to the tracks to prevent the wind from moving them. And, being temporary, does not require foundations. In addition, the containers are modular and the rail infrastructure is not compromised. Self -consumption. The idea is that this solar solution feeds the internal consumption needs of SNFC, as well as local uses around the facilities. The potential is gigantic, but, although AREP considers that it is possible to export this solution to both Europe and the rest of the world, we must wait to see the results of the pilot project. In addition, the idea would be to implement this system in out -of -service railways, all to add energy to the network that operates SNCF, since 80% of the national trains of the same work with electricity. In addition, he has the commitment To deploy 1,000 MW for 2030, and fill the panel tracks would be a good support. Next steps. The following steps of the Solveig project will focus on improving system efficiency and reducing costs to make it viable on a large scale. Although there is still no definite calendar for industrialization, the potential is evident: SNCF has more than 113,800 hectares of operational land that could become authentic solar parks over rails. In short, if the project gives good results, it is only a matter of time before more countries are uploaded to this new “train” of renewable energy. And, speaking of Switzerland, they are very committed to not shaving their green fields and, apart from the panels on the train tracks, also They are installing them on road walls. We just hope this experiment Do not leave like the one on the solar roadalso in France. Images | SNCF, Arep In Xataka | The bats of Spain live times of uncertainty.
