Put solar panels in space has never been profitable, but there is something that motivates the current interest: its military use

by

The old idea of ​​collecting energy from the sun from space to transmit it uninterrupted to Earth has always collided with the huge costs and technological barriers that have prevented their deployment. Until now. A global interest. Governments and companies around the world seem to have a renewed interest in space solar energy. The drastic drop in launch costs, thanks to the emergence of reusable rockets such as Spacex, could have cleared the main economic obstacle from the equation. The necessary technology has also matured in parallel: solar panels are lighter and more efficient, and wireless energy transmission (microwave or laser) is more advanced. The same with robotics, which will be necessary to assemble the stations in orbit. The military factor. As with any renewable project, the energy transition and emission commitments are the engine of this new effort. But behind the recent interests of the Chinese government or the pentagon there is something else: the military potential of space solar energy. “The military utility of transmitting energy to land, aerial or maritime units is obvious,” He said to Spacenews Darpa’s tactical technology project manager Paul Jaffe. Transporting fuel to remote places with tank airplanes can be a usual practice, but “it is not a practical way to bring energy where we need it for defense purposes.” In addition to DARPA, who has conversations with space solar energy startups and invests in the development of long -distance wireless energy transmission, the United States Air Force and Navy are also in garlic. Pentagon projects. The Air Force Research Laboratory (AFR) actively develops space solar technology through its “Space Solar Incremental Demonstrations and Research” program. Its flagship mission “Arachne” will prove in orbit a sandwich panel that converts sunlight into radiofrequency energy to transmit it to a terrestrial receptor. Led by Northrop Grumman, it is scheduled for this year with the explicit objective of providing energy to the forces and reducing the dependence of fuel convoys, which are more vulnerable. For its part, the Naval Research Laboratory (NRL) integrated a module called PRAM into the X-37B secret space plane to prove the conversion of solar energy to microwave. Now the project is part of the space force. What can we expect. Military interest is an important catalyst, and possibly one of the motivations behind the gigantic project of the Chinese Academy of Space Technology (CASC), which will display its first satellites in low orbit by 2028 and in geostationary orbit for 2030. But in the coming years we will also see all kinds of commercial and space agencies, including the European Space Agency with its Solaris initiative, which focuses on viability studies. Despite these progress, the challenges are still considerable. The two major doubts are profitability, in the case of commercial efforts, which will compete with the renewable energies deployed on land, increasingly profitable despite their intermittency. And security, which depends on the fact that you are issued at distances of hundreds or tens of thousands of kilometers are very precise. Maybe let’s see some “fried” birds along the way.

Solar panels have been determined to conquer every building span

by

Self -consumption It has been growing As renewable energies have been integrated into the home. The fact of power Save on the Light Invoice has made more users decided to put solar panels on roof either balconies. However, it seems that converting a house into an energy generator does not know limits. Short. Canadian company Miterx has launched Solarrail, a system of solar railings with system BIPV (Building Integrated Photovoltaics) Designed, as the name implies, to integrate into architecture and generate energy. The integration of solar energy. This system is designed to integrate photovoltaic into the urban architecture and design, such as The company itself has detailed. In addition, its main advantage is that it takes advantage of the space of the boats of the balconies, transforming them into solar energy generators. Integrated panels. Miterx has launched Two versions of the Solarrail: a transparent version (60%) and an opaque. The panels are made up of bifacial solar cells, which allows to capture sunlight both in the front and in the rear. On the one hand, the transparent model has a power of 105 w, on the other hand, the opaque model reaches 390 W. In addition, the system includes support bars, and hidden wiring Solar rail | Miterx Heat is not concentrated. The installation of solar panels in urban areas, although it promotes energy self -consumption, can contribute to the increase in temperatures in cities. A study has demonstrated That these panels absorb up to 90% of solar energy, turning only 20% into electricity and releasing the rest as heat. However, this is when we talk about a solar panel on the railing, while we will have to wait as these integrated railings can avoid the phenomenon “Urban Heat Island”. So is it better than a solar balcony? BIPV systems avoid phenomena as mentioned above. In addition, in this case, as they are bifacial panels, they capture light from both sides, increased efficiency. However, integrated solar panels can affect the risk of fire, As a Norwegian study explains. The distance between the module and the solar balcony can reduce riskwhich does not happen with an integrated system. Forecasts. Solar energy is evolving beyond traditional roofs or balconies, with innovations such as solar railings. These solutions take advantage of the architecture space to continue growing. For its part, European regulations will require that from 2030 All new construction buildings are zero emissions. In this way, we will have to see how technological innovations in the energy sector will grow to comply with the guidelines.

The greatest enemy of Perovskita’s solar panels is heat. Some researchers have found a solution: titanium

by

The commercial viability of Perovskita solar panels is getting closer, thanks to the different solutions over time. However, there is still a big problem to solve to be able to install them, but a team of engineers has managed to solve using titanium. Short. Researchers from the Technological Institute of Georgia in the United States They have achieved That Perovskita’s solar cells are more stable and support high temperatures. The solution was to incorporate titanium into one of the layers. The problem. The incorporation of Perovskita panels to the market has been a challenge because they do not last long when they are exposed to high temperatures. The reason is in one of its internal layers, known as the hollow transport layer (HTL), which allows the movement of electricity within it. This layer, usually made of a material called spiro-feet, begins to crystallize and lose efficiency when the temperature exceeds 70ºC. The solution. The technique used In research is steam phase infiltration (VPI). In this process, the solar cell is exposed to a titanium gas in a low vacuum environment. This allows titanium oxide/hydroxide (Tiox) to integrate into the HTL layer of the solar cell. In this way, titanium acts as a thermal stabilizer, preventing it from crystallizing and ensuring that panel efficiency is not degraded by heat. As a result, solar cells have preserved more than 80% of their original efficiency after 200 hours of 75ºC tests. An alternative to silicon. The study of the study to continue working the Perovskita panels and not those of silicon has been for several reasons. On the one hand, a cost of costs and energy consumption because silicon cells are much more expensive than those of Perovskita. On the other hand, the study has been conducted with financing from the Office of Solar Energy Technologies of the Office of Energy Efficiency and Renewable Energy of the United States Energy Department, so alternatives have been sought for do not depend on Chinain a context of Tariff war. More solutions for Perovskitas. The American study is not the only one who is looking for alternatives in this line. An investigation in the United Kingdom has managed to go one step further developing a method that makes solar cells more resistant to external factors such as humidity, heat and physical wear. Forecasts Until now the technology developed by the American engineers group is in patent. Commercial implementation will be pending if researchers manage to find partners and the future of Solar energy in the United States.

The house that self -stated with its structure, copper and solar panels

by

Origami is Japanese art to bend a role to create figures without using scissors or glue. Through the precision in the folds in a simple sheet it is possible to design unique structures. Following this millenary art, architect Adrian James has managed to design a copper house, giving rise to his house Copper Bottom. On a hill, the house is erected with geometric folds that combine aesthetics and functionality. This house not only defies conventional standards with their metallic structure and lining, but also embodies a vision of the possibility of living in a power plant. Short. The architect Adrian James has designed a house that combines a bold design with energy efficiency. In fact, Copper Bottom It generates more energy than it consumes. Together with his wife, Sarah Shekleton, They decided to leave their home In the Oxford center to build a house in a hill. In addition, as an architect, I wanted to demonstrate How an avant -garde design could integrate sustainability and comfort. How a power plant? Located near the city’s green belt, on a hill, you can see the architectural style both Romanesque and Gothic so characteristic of the city. However, this green house, which took 13 months to build, differs a lot of these styles and functionality. The architect sought energy efficiency so the roof of Copper Bottom It has 37 solar panels, a 20 kWh battery and a air heat pump. The infrastructure of the house is recycled copper, which helps to isolate the sun in summer and allows the passage of heat in winter, in addition, the shape of the house also fulfills a function, thanks to its angular shape it blocks the sun in summer and lets the light pass in winter, avoiding overheating without the need for air conditioning; With its bucket shape, optimize thermal insulation and reduce the waste of materials. Energy community and self -consumption. So far we have always talked about Self -consumption and Energy Community Like two antagonists, one thing or the other. However, the design proposed by the British architect makes both conjugate, since the electricity surplus generated by solar panels can be injected into the electricity grid, benefiting other consumers. It should be noted that in summer, the house generates more energy than it consumes, and the surplus is injected into the electricity grid, which even allows them to receive payments for it. Economic impact. The construction cost of the house was approximately 1.25 million pounds sterling (around 1.55 million euros), a budget that covered both the land and the building. A fairly high price if you have the 37 solar panels and the heat pump. However, this energy self -sufficiency translates into significant savings in electricity and heating invoices, which makes the initial investment more viable in the long term. However, if we have to talk about an investment recovery, it is estimated that carbon debt It will be amortized between 10 to 15 yearsa period that depends on the efficiency of energy systems and the amount of energy that is injected into the network. In addition, the house not only reduces operating costs but can also generate additional income by selling energy surplus to the electricity grid, offering a long -term tangible economic recovery. But isn’t it dangerous? According to The architectthe structure of Insulating panels and recycled copper make it resistant and lasting. In addition, copper is not corrode over time, which means that the house will not need maintenance in decades.

Filling a Tesla Cybertruck with solar panels only costs $ 10,000. Its owners now have 7.5 kilometers extra of autonomy

by

We said when the Cybertruck tesla was presented than the larger and more disruptive electric car of Elon Musk’s company arrived with a Important overpricing and with less autonomy of the fiancee. Since then, sales have grown at an irregular pace. For a time it earned him to become The best -selling luxury vehicle In the United States but a few months later he found that they were not going to be able to continue selling the electric pick-up above $ 100,000 for an indefinite time. What is clear is that Tesla Cybertruck has become something like an “image vehicle.” It is not a purchase based on rationality Well, it is not the most comfortable car and, Not much less, the most capable outside the asphalt. It is a purchase that aligns the driver with the most outgoing facet of Elon Musk’s products. Part of the interest raised by Tesla Cybertruck is in its ability to adapt, supposedly, to any circumstance. His facet has been highlighted to spend a few days in the field (although his finishes to camperize the model Leave much to be desired) and has unleashed the imagination of the owners to the point of transforming it into A tower with wheels and metrallet. And with that last purpose, that of carrying out something unexpected, a company has proposed to increase the autonomy of electric car based on putting solar panels distributed throughout the body. It doesn’t seem the best idea. An extra ridiculous at a very high price The transformation of this tesla cybertruck It could be seen live During the past Ces of Las Vegas. There, the company Sunflare Solar presented the electric pick-up wrapped in flexible solar panels that aim to expand the completely electric autonomy of this electric car. Or, rather, we should say that the case may be free of charge for a few kilometers. Few, if we take into account the price of the transformation and the results that are presented in the best conditions. According to the company’s accounts, collected by Electreck, Sunflare aloner promises to be able to travel a few extra kilometers daily for the modest price of $ 10,000. They believe that with their flexible panels distributed throughout the body can be obtained up to 1.5 kW extra daily. Assuming a consumption of 20 kWh/100 km, we would be talking about just 7.5 kilometers. The figure is far from what Elon Musk who before launching his Tesla Cybertruck mentioned that it would be offered with the option of adding solar panels on the roof that would deliver up to 25 kilometers of extra autonomy. Something that, obviously, has not occurred. Who could make sense for? Well, we could imagine that if we want to camp using the Tesla Cybertruck for our trip we can always use the vehicle to feed different devices. In that case, 1.5 kWh of extra power will always be of great help since we will not be draining the battery at all. In fact, to the company that has presented this option specialized in the use of solar panels in the roofs of the homes but, also, On the ceiling of camperized vehiclesFor example. Of course, we must bear in mind that we are talking about an “improvement” that costs $ 10,000. And, to this we must add that the electric car was sold as a kind of vehicle to the proof of any damage. Its body, of steel, is designed to not suffer with the blows and cover the entire body of solar panels is to buy all the ballots to leave us good money if someone brushes our vehicle. The effectiveness of solar panels in vehicles is a pending task. At the moment, no one has managed to get a good enough performance for it to deserve to invest in technology. Manufacturers like Mercedes continues to study their possibilities But, until now, everything has remained in an auxiliary element for feed electrical devices of the vehicle without increasing consumption so the profit is minimal.

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.

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

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.
