Europe wants solar panels without forced labor. The only problem is that almost everyone comes from China

by

In the early 2000s, Europe was consecrated as The largest solar energy manufacturer worldwide. After more than two decades, that dominant position is a memory against the unstoppable advance of China, which has achieved that more than 80% of global production leaves its factories. A paradigm shift. China has a very particular look of seeing the world in the long term, thanks to that philosophy he has managed to position himself as a leader in solar energy. His method has managed to manufacture cheapest solar panels thanks to a subsidy strategy, vertical integration and almost absolute control of supply chains, such as has detailed Bloombergnef. Meanwhile, European manufacturers have had to compete with those priceswhich has triggered a wave of factor closures, bankruptcies and personnel reductions. Europe’s response. The old continent wants to make its own solar panels again, but motivated by an ethical and geopolitical pressure in the sector. According to Financial TimesThe scrutiny over the Xinjiang region, in China, has grown, which concentrates about 20 % of the world production of polysilicio and where various Western governments have denounced violations of human rights and forced labor against the Uigur population. Faced with this, countries like the United Kingdom have taken a firm position. In April, the British Government declared that your state energy company may not use solar panels linked to forced labor. This ethical trend could force European solar developers to rethink their supply chain and prioritize more transparent suppliers, even if they are less competitive in price. There are already measures underway. On the one hand, in a more ambitious attempt to recover part of its energy autonomy, the EU approved last year The Net Zero Industry Law. This regulation forces to consider not only the price, but also criteria such as the resilience of the supply chain, the environmental impact and the local origin by making public purchases of clean technologies. On the other hand, European products will be prioritized in tenders to equip hospitals, public buildings and other state infrastructure with solar energy. According to Solar Power Europe for Financial Timesthis regulation could create a market of up to 9 gigawatts of solar capacity for “resilient” products already in 2026. But the numbers do not lie. The distance with China is abysmal. Today, Chinese solar panels are sold at about $ 0.09 per watt, a radical decrease from the dollar per watt in 2012, According to Bloombergnef. European companies simply cannot compete in costs compared to the scale and efficiency of the Chinese model. There is something more background. Not only is it a matter of assembly, but strategic minerals. In a broader context, starting a mine can take up to 17 years since it is activated all protocols. Instead, China has been assuring its sources of lithium, rare earths, copper and silicon for 20 years. In this way, even with the new EU regulations working perfectly, the so -called “resilience market” would cover less than 14 % of the solar capacity added in Europe, According to Financial Times. And there would be no guarantees that these panels be produced by European manufacturers: they could come from India, South Korea or other countries that do not use materials of Chinese origin. Will it go through the hoop? Here the main question that arises is: Is Europe ready to assume the political economic cost of reindustrializing its solar sector? Or will it accept the dependence of a cheap but geopolitically complex supplier? For now, the measures seem insufficient to significantly alter the structure of the market. The European energy transition progresses, but does it mounted on Chinese panelseven when their governments promote technological and ethical sovereignty speeches in commerce. Europe has aroused a race that she helped to start. Recovering the lost terrain will be difficult. The sun does not expect, and China already closed the umbrella.

Do not get night on solar panels

by

Suppose you acquire the power to cancel the night in a certain place in the world; of reflecting sunlight from space to illuminate something concrete, so that it is made from day in a given area. What would you use it? Orbital reflect. A Californian startup wants to obtain this power to illuminate the photovoltaic panels in the hours close to dawn and sunset, when I miss its renewable energy, and when the energy companies could sell more. Orbital reflect has just received 20 million dollars in financing, which will use to deploy a constellation of satellites equipped with gigantic mirrors. Its objective is to reflect sunlight towards Earth on demand. The sun to the letter. The concept is simple: to increase the production of solar energy on the earth directing sunlight to the large photovoltaic plants of the soil before dawn and after sunset. Like the space solar stations, but without the complications of concentrating the energy in a laser or microwave beam, placing large mirrors in orbit would significantly expand the light time that a solar farm receives to generate electricity, solving one of the great Peros of solar energy: its intermittency. The company has already performed tests with a mirror in a hot air balloon at almost 3 km on a solar farm, generating 500 watts of energy per square meter of photovoltaic panel with approximately half of the brightness of the sun. A first demonstration. The first orbital reflect mission is scheduled for the spring of 2026. A demonstration satellite will test a 18 x 18 meter mirror made with mylar plastic tensioning to form a solid reflective surface. It is expected to reach a brightness of 0.1 lux, comparable to a full moon on a clear night. The mission aims to illuminate 10 iconic locations during the night to generate dissemination and public interest. An ambitious goal. The initial idea contemplates a constellation of 57 small satellites in a synchronous polar orbit with the sun, about 600 kilometers of altitude. They would provide about 30 additional minutes of sunlight to photovoltaic plants. In the long term, orbital reflects plans to launch a constellation of thousands of satellites with much larger reflectors, up to 55 x 55 meters. On this scale, the total luminosity of the constellation would be comparable to that of the sun at noon. Other applications. Although the impulse to solar energy is the final objective, the company has plans to generate short and medium term income with other applications. Since its foundation in 2021, the company has received more than 260,000 applications from 157 countries for its sunlight delivery service. Among future services, they offer the lighting of night construction projects, public events, disaster help efforts, and defense operations. “We want it to be as easy as possible: you enter a website, you tell us your GPS coordinates and we send you some sunlight after dusk,” explains the CEO of orbital reflect, Ben Nowack. Science fiction made reality. Image | Orbital reflect In Xataka | Space energy never worked. A military escalation in orbit is making it come true

Having solar panels at home sounds very good in case of national blackout. The problem is that they don’t work

by

The national blackout that Spain has suffered It has been historicalbut has also sown the doubt. While the vast majority of citizens ran out of light, in the street there was “life” in some supermarkets or marques that made the use of other renewable alternatives. Surely also, today more than ever many will ask about the need to have a solar installation in their home, which leads us to another question: how does a network of domestic panels work before a national blackout? Installation in normal conditions. Before talking about the case of a blackout as the one that occurred in Spain, it is convenient to explain the most basic of A “standard” installation In a typical home. In most cases, solar panels capture the radiation of the sun and generate what we call DC (DC). This current passes through an investor that converts it in turn in alternating current (CA), and that is precisely what we use in homes. In Spain and in almost all countries, most solar facilities are connected to the electricity network (known systems as on-Grid). This allows, on the one hand, to consume solar energy directly in the house. On the other, pour the surplus to the network (which entitles economic compensation, such as the net balance or Simplified compensation). Finally, of course, it allows you to receive electricity from the network when there is not enough solar generation (for example, at night or on cloudy days). The problem occurs when there is a situation like that occurred yesterday. Installation in blackouts. When you have a photovoltaic installation in the house of only panels and there is a blackout, something contradictory but very important happens: even if you have solar panels working, the sky is sunny and the beginning of the day, your house is also It is left without electricity. As? Yes, this occurs by security regulations (for example, in Europe under the standard VDE 0126-1-1 and similar), all solar investors connected to the network must detect the loss of tension and turn off immediately, is what is called Anti-Isla protection. The reason? The reason for this “cut” is to protect network maintenance technicians: if there were thousands of houses by sending electricity to a supposedly “dead” network, it could be lethal for workers They are at that time repairing the failure. Therefore, if you have only solar panels connected to the network, you cannot use electricity during a blackout. Your solar panels are automatically disconnected. There is no more. The solution: batteries. If you also have batteries, the thing changes, although here the situation varies depending on the type of investor and configuration you have. If you have hybrid investors (solar + battery), there are modern investors that already allow to continue operating in what is called Island or back-up mode. This means that when they detect a blackout, they are physically disconnected from the network and come to feed only your house using solar energy and energy stored in your batteries. In addition, there are also systems for backup investors (The so-called back-up inverters), where a separate system is used that can feed a specific part of the house (for example, fridge, essential lights or internet). One More Thing. But even so, for this to work you need lithium or lead batteries properly sizeda hybrid investor compatible with operation in island mode or an inverter with backup function (Back-UP), a automatic cutting system that separates your home from the public network in case of blackout guaranteeing safety, and finally an electrical panel prepared to isolate non-essential loads (for example, it makes no sense to keep the electric oven or air conditioning on if the energy is limited). In any case and to place all this in perspective in the Spanish landscape, only 33% of facilities Current domestic lots in Spain include batteries. This means that most households with solar panels would continue to suffer electric cuts during a blackout like the one that occurred yesterday. The reasons are very varied, but the extra cost of investment of them after the solar installation (already large) is key. The promise of self -supply. All this leads to a final question: Is it possible to be self -sufficient (energetically) in Spain? The short response is no. The promise of solar self -supply on the peninsula is based on taking advantage of the high solar radiation (Spain receives on average between 1,600 and 2,000 kWh/m²/year) to generate clean energy and reduce dependence on the electricity grid, especially in single -family homes. Thanks to photovoltaic self -consumption and the Price drop Of the solar panels (more than 80% have fallen in the last decade), today it is technically possible to cover between 60% and 80% of the annual consumption of an average house in Spain only with solar energy, and in some cases, almost 100% If appropriate storage batteries are installed (although with the network hitch). The problem. However, self -supply has important limits: solar production is intermittent (there is no generation of night and lowers a lot in winter or cloudy days), the batteries remain expensive (between 4,000 and 9,000 euros a complete domestic installation) and its capacity only allows a few hours or days of autonomy without network. Plus: We already said it, the current legislation requires that the systems connected to the network be disconnected in blackouts if they are not equipped to function in Isla mode, which implies that, without a specific design (and of large disbursement), even with solar panels, you could run out of electricity in general cuts.

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.
