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.

The blackout in Spain has demonstrated which is the ideal means to inform in a crisis: the radio

by

In the minutes that followed the Broady in Spain and Portugal At 12:32 yesterday, millions of people They wondered The same: “What happened.” In other crises, television, newspapers and of course the Internet are the clear alternatives to find out what is happening, but yesterday that was not possible. Almost everything failed, but there was a means of communication that allowed us to keep us informed: the radio. Where is the FM radio of the mobiles. The fragility of our communications caused the radio to erect as a unique solution to keep us informed. The mobiles had support for FM radio years, but this feature has disappeared in all current models. In fact It went from being an extra desired to an exclusive function of cheaper models. Something older mobiles do have that function by connecting headphones (which bend as antenna), and that allowed those who still have any of those mobiles could be informed thanks to that functionat least while the mobile battery lasted. Some brands keep them in some models. Xiaomi is one of the manufacturers that still includes support for FM radio in some of its Redmi family models, but of course not all. He Xiaomi Redmi Note 14s or the Redmi 14c They are good examples. The normal thing is that in recent terminals we will not find that option, which we can enable in older mobiles (such as Little m5he Motorola G73 5g or the Samsung Galaxy M23 5g) and also in input range terminals and in less extended brands such as Doogee or Ulefone. Radio as informative lifeguards. Without light there was no television or wifi in houses and offices, and connect to the Internet It was an odyssey all day: Mobile lines, the only ones that could give a way out, worked irregularly … If they worked. And yet, the radio worked without apparent problems. Transistor to batteries. Meanwhile, those still kept a battery transistor at home could be informed thanks to the radio stations continued to broadcast during the blackout. These transistors became the salvation of many citizens, who either had radios in their homes or gathered in the streets around vehicles with analog radios or that could listen to the radio What other people had in the streets or on the terraces. They were also one of the products that They sold out more quickly in shops that remained active during the blackout. Why the stations continued to work. Augusto Molina and Héctor Zafra are respectively the technical director and the technical manager of the SER, and explained In a piece in this medium The way of proceeding in these emergency cases. The first thing they did was turn off monitors and all the teams that could be turned off to save to the fullest. That allowed maximizing the autonomy of emergency equipment that is used in these cases, and that were the key both in the SER chain and other stations. Electrogen equipment. These structure (motorogener) groups are machines that generate electricity through an internal combustion engine. They make use of fossil fuels (gasoline, diesel) and allow generating electricity while the fuel lasts. Are the teams that They are used in hospitals to maintain a good part of the essential services during this type of energy crisis. Several stations survived the blackout. National Radio of Spain kept for example emissions, such as They also did wave zero, the Cope chainthe aforementioned chain and other stations – although not all – and broadcasters who could continue to inform thanks to those emergency teams that were activated during the blackout. Radio as lifeguard in emergency situations. What happened yesterday has revealed the relevance of the radio as an ideal means of communication to emergencies. There have been numerous cases in the story in which that has become evident. In our country they stand out for example The coup d’etat of 23-F In Spain, in 11m or more recent attacks The Dana that ravaged the Valencian Community and that caused the majority of the electric laying. Transistors, both in one and another, allowed to remain informed.

In full blackout throughout Spain and confusion among the population, an alert system shone for its absence: Es-Alert

by

Yesterday we attend an unprecedented event in our country. From one moment to another and in a matter of five seconds, 60% of all energy vanisheddisappeared. The entire peninsula ran out of light. The reasons are unknown how it was unknown in certain points of Spain that the blackout had been general. The light fell, ergo the wifi. Telecommunications, mobile networks fell, and networks were saturated. Contact family and friends to know if they were fine was an odyssey, as was accessing to the media and social networks to inform themselves of the last hour. No one knew what was happening, its reach, the reasons or the state of the situation. In such a context, it is worth asking what happened to Es-alertthe emergency alert system. Who is-alert depends on. The Civil Protection alerts system was launched on February 22, 2023 and serves to send notices to all mobile phones within an affected area. It is integrated into the national alert network and, therefore, is managed by the Ministry of Interior through the National Center for Emergency Monitoring and Coordination (CENEM) of the General Directorate of Civil Protection. Notice example received through the ES-Alert system | Image: mobile xataka This system is known as “112 inverse” and is available in “any part of the Spanish territory with mobile telephony coverage, either 2G (GSM), 3G (UMTS), 4G (LTE) or 5G”, as They explained from Moncloa The day of its launch. Civil protection, meanwhile, exposes that “the ES-ALErt system is available to the Emergency Coordination Centers of the Autonomous Communities in the framework of the National Civil Protection System” and that these centers, together with the aforementioned CENEM, are the “responsible, within their area of ​​competence, to define and issue the alerts when the situation requires it.” In a nutshell, that competition falls to the Autonomous Communities. What situations is used? According to Moncloa, Es-Alert is designed for phenomena such as “floods, fires, adverse meteorological phenomena, volcanic or chemical accidents, among other emergencies.” The question is what happens to this system when there is no electricity, when telecommunications are falling and a very high percentage of the population has no coverage. A mobile will not receive the notice if it has no coverage or is in plane mode, although it will do so when you recover the signal The networks worked (a time). The mobile network remained active for a while thanks, in part, emergency generators. VodafoneMasorange and Telefónica They have confirmed that although the blackout had affected telecommunications services and the mobile network, part of the system had supply thanks to electric generators and batteries. Es -Elert depends on that infrastructure to work, the question is whether it would have been effective. Lights and shadows. While it is true that Es-Alert is practically agnostic to the device and the version of the operating system, its effectiveness depends on the fact that there is electricity and that the receiving phones have coverage. Assuming that the ES-Alert system was available (because as we already know, there was no electricity supply), the reality is that an important thickness of the population would not have received the warning at the time because it did not have coverage. They would have received it when recovering the signal in the event that the emergency remained active in the area, but there is no guarantees that, by then, the notice would have been useful. Image | Fré Sonneveld Social networks. Public entities and organizations, which They urged the user to save battery and limit the use of mobilethey made their official communications through social networks such as X. Access not only to this social network, but to the media that echoed this information, it was not always possible due to the lack of coverage and mobile data network. The always eternal radio. The best informed citizen yesterday was the one who had a ancient operational radio thanks to two AA batteries. The radio works independently that there is coverage, mobile network or wifi. Emergency equipment They do not communicate by Walkie-Talkies By custom, but because in a fire in which everything has fallen, the radio will continue to function. If the broadcaster and the receiving device work, there is communication, and that is what happened precisely yesterday. The radios continued to function and counting the last hour of the blackout, which shows that an invention of the late nineteenth century is still important in the middle of 2025.

Why the fall of telecommunications was so unequal during the blackout in Spain

by

Spain plunged yesterday into a unprecedented energy blackout. A complete fall of the national electricity grid that caused problems in essential services and, above all … communications. A few hours after the Energy zero throughout All Spanish territoryoperators such as Vodafone Spain kept active 70% of their mobile network. The question is how. How the network was kept alive. Despite the national blackout, Some operators like Vodafone They made their mobile network remain active thanks to reserve generators. Although popular perception may be that the network connection is a purely wireless technology, it depends completely on telephone stations (what we commonly know as antennas), some that need electricity to function. Before scenarios such as yesterday, all protocols were activated to keep them alive despite the disconnection with the national electricity grid. This was achieved thanks to two main actors: backup batteries and structure. Diesel and batteries. Groups such as Masmobic confirm Xataka that this maintenance of the network infrastructure was achieved thanks to its reserve generators located in the stations themselves, but also to displaced electrogen groups to each area. In Spain, the Low voltage electrotechnical regulation (REBT) It demands support systems in critical infrastructure. Image | Vodafone The autonomy of these systems is limited and variable. That a station can be fed for more or less time depends on the state of the batteries, the capacity of the generators and the logistics of the fuel supply. In the best case, structures can keep the service for 24-48 hours. If we talk about reserve batteries, autonomy usually ranges between two and eight hours. This is the main reason why Some networks continued to work after the blackout and also for which others began to fail after a few hours. A progressive fall. Vodafone managed to exceed 70% activity in the network at 3:00 p.m., maintaining autonomy in its network, datacentes and systems control centers. As the hours were advancing, the figure fell. At 23: 00h, mobile traffic fell to 60% with 50% of active nodes. Reason? After more than ten hours of blackout, some of the reserve batteries began to run out. Why I had no coverage and my neighbor yes. During the blackout, access to the mobile network was (and remains) variable, and this is due to several factors. The main is the difference in backup feed systems (SAI or generators) that have mobile phone antennas. Not all base stations have the same capacity to continue working without electricity supply: some have batteries with little autonomy, other generators that require fuel (diesel or gas), and their availability and maintenance vary. In the same way, Not all operators use the same infrastructure. Each company has its own (or rented) towers and nodes, which means that two mobiles can be connected to different antennas even being in the same area. Thus, it is possible that the antenna of your operator has stopped working before, while that of your neighbor – with another operator – remains active longer. The small operators. Vodafone proved to live up to 70% of the coverage, but smaller companies, with fewer nodes to connect and lower capacity to supply energy, faced a more complex situation. The so -called virtual mobile operators (OMV) “As Digi, Finetwork, Pepephone, Lowi, etc.,” do not have their own infrastructure. Instead, they rent access to the networks of the greats (Movistar, Orange or Vodafone). The immediate translation is that its operation depends completely on the conditions of the wholesale operator in each area. If the antenna to which a user of a secondary operator connects does not have sufficient support, or if your host network prioritizes other services, the user runs out of coverage more quickly and for longer. How long would they last before chaos. Telecommunications networks can survive without electricity supply for a limited time, but are not designed to resist prolonged blackouts. In the best of the scenarios, with well -supplied structures and batteries in good condition, some stations could be kept operational between 24 and 48 hours. Beyond that threshold, everything depends on the operator’s logistics capacity to replenish fuel. In that scenario, the first to run out of coverage would be users connected to secondary nodes or small operators, while critical or priority areas (hospitals, security forces, command centers) could maintain connection for longer thanks to emergency protocols.

85,000 people jumping to the rhythm of Catholic slogans in cyber are just one more piece of the Hakuna Puzzle complex

by

The figure of Pope Francis Vartebra the origin and also the last milestone of Hakuna’s musical faction. It is at the origin of this Catholic youth movement founded in 2013 in Madrid by the priest José Pedro Manglano, in response to the mood of Pope Francis during the World Youth Day (WYD) of Rio de Janeiro. There the Pope encouraged young people to “make mess”, and Hakuna has taken it to the letter, riding a very notorious cyber this Saturday. Not only music. The growth of movement has been exponential. He was born as a group of related young people in part to Opus Dei, who met in San Josemaría de Aravaca, but soon began to attract other young people. He started as an association of faithful, many of them lay, who gathered privately, but soon began to extend, first in Spain, and since 2018, internationally: Hakuna is currently in more than twenty countries and more than 70 cities around the world. But above all, music. No one escapes that this is the nucleus of Hakuna’s appeal: music always was part of Hakuna’s initial meetings, which in 2015 take shape like a first album. It is the second, ‘My poor mad’, which gives them a greater impact. Since 2022, Hakuna Group Music has experienced exorbitant growth, reaching milestones such as its concerts in the Vistalegre Palace or Wizink Center (17,000 tickets and SOLD OUT In a few hours) and add millions of listeners in social networks and Spotify, where on more than one occasion they have come to be In the most listened to top. Many people. The group is, again, organized and directed by Manglano, and there are no visible heads or stars in it: there are some forty artists of which up to twenty can get to the stage simultaneously. There are no leaders or leaders and the songs are composed collectively, following the slogan “we live what we sing and sing what we live.” His carefree style and away from strict orthodoxy is what has become hits to songs like ‘Hurricane‘, popular even out of religious environments, and already with 11 million views On YouTube. The resurrection party. This is the name that received an act organized by the Catholic Association of Propagandists (ACDP), which would commemorate the resurrection of Jesus with which Holy Week concludes, but which also became improvised chosen the newly deceased Pope Francis. Hakuna sang his theme ‘Mercy ‘according to them one of the Pope’s favorites, and were accompanied by artists related to the Catholic faith such as Beret, DJ Octopus, always like this or Cali & El Dandee. The event, which is already for its third edition, congregated more than 85,000 people. Party and prayer. Related to that purpose of “making mess” proposed by the Pope and that appears very clear on the official Hakuna website, no doubt what congregates 85,000 people in cyber on a Saturday is that feeling Catholic is not at odds with the party. This is corroborated by the many immersion chronicles in the phenomenon they have carried out newspapers such as Independientewhere statements of faithful who follow Hakuna are collected even on trips in different countries, and where what the songs help to immerse themselves in the Catholic faith, the accessible and direct of the songs, and how that fits, in its own way, in its own way, with a beer after a concert of the group is underlined. The musical arm. The Hakuna phenomenon is so extraordinary that it has become examined in Papers Academic who inquire into their role as a secular organization and as a reinforcement of a collective identity. In this studyentitled ‘The Hakuna Movement: Organizational Structure and Strategies for the Re -Christianization of Youth in Spain’, the authors talk about how the spiritualization of the leisure in recent years (and Events like Soul Week) It has a lot to do with Hakuna’s success. The viralization of the music band has given context to the movement, creating concepts such as “revolutionary chosen” or “pringado”, which is what the same call themselves Hakuners and that are present at the ‘Qaos’ album of 2022. More pop gospel. Hakuna Group Music are not the only examples of this new wave of Catholic evangelizers through pop music. Much more common in Latin America, with singers such as Athenas or veteran Martín Valverde, groups such as The desert voicewith seven members of which three are priests. Luis Poveda He is also a priest and singer -songwriter, and Wheat 133 They are linked to the missionary NGO Jatari and youth evangelization. And there are many more, with names such as Ain Karem, Álvaro Fraile, Olivo outbreaks, Jesús Cabello, Luis Alfredo Díaz or Maite López.

This is the situation of trains in Spain after the blackout

by

Lost trains in the middle of nowhere (No chance of rescue three of them still at night), all completely stopped nearby services and the large cities collapsed in traffic shot at the lack of mobility in the suburban. The blackout that the April 28, 2025 In Spain he left us without trains and still, despite having recovered almost the entire electricity grid, the rail service continues to present some holes. This is what we know, what works, what does not work and how much we hope to return to normal. Half -gas trains With the generalized blackout yesterday, the Spanish rail system was completely stopped. To shelter travelers, the main Spanish train stations remained open at night although even this was not enough since Some people were out of them covered all capacity. Cercanías services With Renfe’s last update at eight in the morning, the situation is as follows. Lines that work normally or partially: The Cercanías de Asturias and Cantabria lines work normally. Madrid Cercanías: 50% planned service in all lines and in the C5 recovered between Humanes and Atocha and the sections between Pinto and Aranjuez and Guadalajara-Alcalá de Henares, which will not circulate from the beginning. Valencia Cercanías: 100% planned service in C2 lines from Valencia to Xàtiva and C6, without tension in the C1 in the section between chair and gandía. Suspended services: Rodalies in Catalonia The nearby Alicante, Zaragoza, Cádiz, Sevilla, Malaga, Bilbao and San Sebastián do not work. Medium and long distance and high speed services The following services do not work: Avant and Media Distance Services in Andalusia Medium distance and Alvia services in Extremadura High performance services of Ourense-Santiago de Compostela-Coruña and Vigo-Santiago de Compostela-Coruña. Avant service from Toledo Connections between Medina del Campo and Salamanca Metric width between Ferrol – Ortigueira and León – Guard. The following high -speed and long distance lines are working since the beginning of the service: Madrid-Barcelona. Madrid-Valencia/Murcia/Alicante. Madrid-País Vasco. Madrid-algeciras. Malaga-Granada Madrid-Asturias Madrid-Santander Madrid-Córdoba Madrid-Seville Lines that should recover normality throughout the day: Lines without service and without forecast to recover them until new notice: Madrid-Huelva. Madrid-Badajoz. Madrid-Cádiz. Madrid-Galicia. Madrid-Salamanca. Madrid-Logroño. Barcelona-Aliante (Euromed). Basque-Barcelona country. Renfe points out that affected travelers can request the return of the ticket or the change without cost in the Renfe sales channels. To make a trip, the passenger will be able to go to the stations and look for a way to comply with one of the available squares. Metro services As for the operation of trains in the Metro network of the big cities, the situation is as follows: Private services Iro has announced that has recovered normality in the services provided in the corridors of Madrid-Valencia and Madrid-Barcelona.

Huawei plans to advise Nvidia in China. It has a new GPU for theory that in theory is extremely powerful

by

Huawei is putting all the meat on the grill to absorb so much share in the Chinese GPU market for artificial intelligence (AI) as I can. And it is that the entry into force of the last US sanctions package is compromising with all probability Nvidia leadership in China. The US Department of Commerce It has imposed restrictions to the export to the country led by Xi Jinping of The H20 GPUand this in practice means that this chip presumably will not reach the Chinese clients of Nvidia. This last company has announced that this ban will cause a hole in its accounts of 5,500 million dollars Due to the commitments linked to the H20 GPU that had already acquired the reserves of this chip that it will not finally satisfy. Some of the Chinese companies that have bought large amounts from the H20 chip to NVIDIA and who presumably planned to continue doing them are Tencent, Alibaba or Bytedance, but at the current situation they will have to resort to an alternative. And Huawei has put it on a tray. The GPU Ascend 910D aspires to snatch the leadership in performance from Nvidia Huawei reacted immediately to US sanctions. And is that just a few hours after the entry into force of the new regulation of the Department of Commerce He presented his chip for the ascend 920a solution that is clearly destined to occupy in the Chinese market the gaps that the NVIDIA H20 GPU is going to leave. This proposal will enter large -scale production during the second half of 2025 using 6 NM integration technology that have presumably developed elbow with Huawei elbow and SMIC. Until now Huawei wanted to get his hardware to dominate the inference processes in AI However, this is not the only asset that Huawei has to increase its market share both in China and beyond its country of origin. And is that, According to Reutersthis company is preparing to start the testing and validation phase of a new GPU for AI: The Ascend 910D chip. Unlike the GPU Ascend 920 that, as we have seen, presumably aspires to compete with the NVIDIA H20 chip, the GPU Ascend 910D seeks to overcome the performance of the chip NVIDIA H100. If this movement is confirmed, already priori this information is reliable, it will be evident that Huawei will have chosen to fight in all hardware market segments for the nvidia. Until now this Chinese company wanted to get its hardware dominate the inference processes in AIand not the training of the models, as Georgios Zacharopoulos, a senior researcher of AI who works on the acceleration of inference in the Huawei laboratory in Zurich (Switzerland) points out in this statement. “The training is important, but it only happens a few times. Huawei focuses mainly on inference, which will ultimately give us access to more customers,” says Zacharopoulos. Inference is broadly the computational process carried out by language models with the purpose of Generate the answers which correspond to the requests they receive. In any case, the information we have reflects that the GPU Ascend 910D will allow Huawei to compete with the chips for the most advanced NVIDIA both in inference and in training.

The Ministry recalled the existence of paid permits

by

Spain has lived a Unpublished day in its historyafter him Mass blackout which kept the entire Iberian Peninsula including Portugal. The incident forced a good part of public transport services, as well as at the close of many companies before the lack of electricity supply and possible security problems. Given this unpublished event, the Ministry of Labor and Social Economy issued several communications through its profile in the social network X in which it remembered the workers: “The Government guarantees the protection of working people in the face of electricity supply problems. Blooded permits are available for affected workers.” Remunerated permits by force majeure As happened with the DANA or other adverse phenomena, the ministry reminds the workers that the Workers Statute It provides special coverage for cases classified as force majeure, preventing companies from retaliation in the form of layoffs or salary sales for this reason. In article 37.3 section G, which addresses the regulations on weekly rest, parties and permits, the statute of the workers establis Imminent, including those derived from a catastrophe or adverse meteorological phenomenon. “ As they remembered from the Ministry, they are covered by the permission paid for causes of force majeure: Because the official recommendations of not moving if it is not strictly necessary given the serious traffic incidents that left streets and roads without light signaling and the great traffic jams that this caused, this article of the Statute of the Workers is applied. In addition, the regulations also collect the assumption of doing the work remotely provided that the networks allow their development, something that could not always be carried out before the fall and saturation suffered by the entire communication network throughout yesterday’s day, and The impossibility of feeding computers. Although most of the services have already been restored with the return of the electricity supply, the official communications warn that, during the day today, Incidents can still be registered In the different services, so it is possible that, in some cases, today they can also benefit from that paid permit when it is not possible to move to the workplace. However, despite the incidents in transport that may remain to be resolved in transport, communication networks remain operational, so the remote work option is viable when possible.
