Balcony power plants are trendy. The photovoltaic company Greenakku is now going one step further and has presented a solar system for garden fences. But how high is the energy yield?
In recent years, the prices for solar systems have fallen. The energy from the sun is now one of the most affordable forms of energy. So it’s no wonder that many homeowners are now buying a photovoltaic system. But what are the options if there is no space on the roof or balcony?
The solar company Greenakku now offers a solution. Because with a so-called fence PV set, property owners can turn their garden fence into a solar system. The requirement: The fence is in the sun and can bear the weight of the structure. Depending on the set, there are one or two solar panels for this.
Solar system for the garden fence from Greenakku
In addition, a micro inverter and the necessary mounting material are included in the scope of delivery. Basically, according to the manufacturer, installation works best with so-called double rod mat fences. On the other hand, if you have a different type of fence, you can also adapt the attachment with a little manual skill.
However, once screwed on, the panels cannot be easily removed again. As Greenakku reports, the fastening materials are theft-proof. Also worth mentioning: The solar system can only be attached vertically to the garden fence. Mounting in predefined angles is not possible.

Solar fence: Performance differs depending on the set selected
Once connected to the inverter, the system feeds the generated energy into the home network via a safety plug. The cheapest set starts at around 415 euros and contains a solar panel (335 watts peak) and an inverter (300 watts). There is a model with panels on both sides for around 435 euros, the output is then 390 watts peak.
If there are two panels (including two inverters), about 715 euros will be due. With the double-sided system it is around 800 euros. If you are interested, however, you should consider that the sets do not have a connection cable. However, this can be configured when ordering for 22 to 34 euros.
Even if an electrical installation belongs in the hands of experts, the cooperation of builders is required. After all, property owners know best how individual rooms should be designed. The purpose of a room and the furniture in it are decisive for the optimal electrical installation.
Floor plans and on-site inspections
An important basis for optimal planning of the electrical installation is a copy of the floor plan of the respective object. Builders mark the areas on this floor plan in which sockets, light switches, radio, television, hi-fi and EDP connections or lights are to be installed.
If there is already a standard plan for the electrical installation, it can be expanded according to your own wishes.
In addition to looking at the floor plan, it also makes sense to take a close look at the rooms again and mark all the preferred areas for connections. Homeowners should include connections for music systems, televisions, computers, floor lamps, or other electronic devices in this inspection from the start.
Experience has shown that far too few sockets are planned for the standard equipment of a house or apartment. There really isn’t too many sockets. In return, the annoyance is great if there is a lack of sockets afterwards. Based on standard equipment, home builders should plan for the following number of connections:
Kitchen: 10 – 15 connections, for example for refrigerator, microwave, dishwasher, oven and work sockets
Living room from 20 m²: 20 – 24 connections, for example for lamps, music systems, televisions and other electronic devices
Nursery: 8-11 ports
Bad: 4 connections. Two to the left and right of the bathroom mirror and two more at floor level
utility room: 8 connections, for example for dryers, washing machines and multiple work areas
Corridor or hallway: 3-5 connections, for example for vacuum cleaners or for charging electronic devices such as smartphones
Workspace: 8 – 10 connections, for example for technical devices such as printers, computers, scanners or telephones
Outside: 8 connections, for example for electrical garden equipment such as lawnmowers, refrigerators, radios or TV sets
For garages, basements or hobby workshops, devices with a higher voltage are often used. In this case, a so-called three-phase AC socket for 400 volts of power current is a good choice. A connection with a higher voltage is also particularly suitable for a sauna.
If you want to save money, you should try to find cheap electricians nearby. Experienced specialists generally know that safe electrical distribution must be divided into at least four fuse rows. Separate living areas such as bedrooms, living rooms, hallways, bathrooms or kitchens should each have their own circuit with a circuit breaker. It is just as important to separate light and socket circuits from each other.
In general, high-performance household appliances such as washing machines or dishwashers each require their own circuit.
A residual current circuit breaker is also used for overall protection. Experts recommend a special safety switch for the bathroom.
Third tip: Play it safe – with empty pipes
Laying electrical installation pipes under plaster is a good choice for renovations or new buildings. These empty pipes offer tenants or property owners the opportunity to expand the electrical installation as required.
Additionally laid pipes are well suited to subsequently lay a technical basis for connections for switches, sockets, light sources, alarm systems, video surveillance or intercoms. The empty pipes ensure that when the electrical installation is adjusted, the walls have to be completely broken up again.
Smoke detectors are lifesavers, saving people from suffocation or burns while they are sleeping, for example. A few seconds are enough for death to occur as a result of smoke inhalation. This scenario is avoided by smoke detectors that alarm in good time.
The smoke detector requirement for private living spaces applies nationwide in this country.
There are detailed regulations, for example, in the state building regulations of the individual federal states.
Fifth tip: Increased security with overvoltage and lightning protection
Experience shows that many people grossly overestimate the protective effect of tall buildings. It is a myth that lightning always strikes the highest point. The only effective protection against lightning damage is a professionally installed lightning protection system. Lightning strikes within a maximum radius of two kilometers reach other houses via cables and cause surge damage.
In order to prevent damage to sensitive devices such as televisions or computers, multi-stage lightning protection systems consisting of lightning and overvoltage protection offer a high level of security.
Permanently installed charging stations for mobile devices are very popular. USB charging sockets or a ramrod attached to the wall fit seamlessly into most room concepts.
In the meantime, even USB charging sockets are available, into which users can plug their own smartphone charging cable directly.
Another option are built-in charging docks, which are optimally adapted to the needs of mobile phone users.
Seventh tip: electrical installation for the outdoor area
Electricity in the garden increases comfort, provides light and at the same time makes work easier. For this reason, it makes sense to include this part of the electrical system in the planning right from the start. Paths and terraces have to be illuminated, pond pumps activated or electronic devices such as lawn mowers connected outside. For these and many other purposes, the external electrics are absolutely necessary. A circuit with a motion detector is recommended for all properties for which floor or wall lights make sense.
A control switch on the patio door is also advantageous for patio lighting. Incidentally, underground cables are particularly suitable for connecting electrical installations outdoors. In order to optimally determine the route of the underground cable, property owners should be aware of the areas in which power connections or lamps are required. If you lay empty pipes in the garden, you can later pull in additional cables if necessary.
Good electrical installation – it’s all a question of planning
Think about tomorrow today: This resolution saves real estate owners many hours of work. Good planning of the electrical installation is an important basis for benefiting from the advantages of a well-designed cable system for years to come.
An artificial intelligence based on ChatGPT should Zalando customers choose their clothes in the future. However, the beta version of the so-called new “Fashion Assistant” will initially only be available to a few customers.
Online fashion retailer Zalando has announced a new digital “Fashion Assistant”. The highlight: An artificial intelligence based on ChatGPT is supposed to help customers choose their clothes. According to Zalando, the AI tool should be available “this spring”. However, initially only as part of a test phase and for “a selected group” of customers.

Artificial intelligence is currently on everyone’s lips, mainly due to the success of ChatGPT. But how do tech companies train their systems? That has the Washington Post researches and analyzes which websites make AI software appear intelligent.
The topic of artificial intelligence has increasingly come into focus due to the success of the AI software ChatGPT. According to estimates, the market with AI in the areas of hardware, software and IT services could be worth around 554.3 billion US dollars in 2024. In 2021, the number was still around 380 billion US dollars.
But what is behind artificial intelligence like ChatGPT and Co. and how are they trained? That has the Washington Post analyzed in a research and scrutinized which websites make AI software appear intelligent.
With which websites does artificial intelligence train?
For their research, the Washington Post “high-quality English-speaking AIs” analyzed. These are trained as so-called “large language models” with the help of websites.
analyzed the Washington Post including Google’s T5 and Facebook’s LLaMA. This analysis is based on Google’s C4 data set, which contains the content of 15 million websites.
How do ChatGPT and Co. learn?
Since AI systems cannot think for themselves, they have to be trained beforehand. Once they have absorbed enough information, they can imitate speech and, for example, conduct conversations or answer complex questions.
Of course, it depends on what information the respective artificial intelligence was previously fed with. Because that’s the only way she can work later.
In the meantime, however, technology companies often try to keep this secret. So does the ChatGPT mother OpenAI. Because the company does not disclose which data sets its AI software uses to train.
The AI analysis of the Washington Post
For the analysis of the websites, the Washington Post collaborated with the Allen Institute for AI. First, the 15 million websites were categorized. Websites that were no longer categorizable or available were excluded from the analysis.
The remaining ten million websites has die Post sorted by how many tokens occur in their data set. This can be individual words or entire phrases.
The websites examined came mainly from the fields of journalism, entertainment, software development or medicine. The websites patents.google.com, a listing of all patents worldwide, and the online encyclopedia Wikipedia are in the first two places.
But dubious websites have also made it to the top. According to research by the Washington Post at least 27 websites identified by the US government as pirate and counterfeit markets.
Questionable content also makes it into the training for artificial intelligence
But not only serious content makes it into the training data of the AI systems. Because although Google and Co. filter the data in advance, racist or radical websites also make it into the list.
Business websites appear most frequently in the analysis. At 16 percent, this category accounts for the majority of AI training sites.
Websites on the subject of technology follow in second place, while journalistic content takes third place. News houses such as nytimes.com, theguardian.com and forbes.com can be found among the first places.

According to the Washington Post above all, that no permission is obtained for the use of the content. The use of radical and right-wing extremist sites is also problematic. Because websites like RT.com or Breitbart.com also appear in the list.
Precisely because of this questionable content, the Washington Post This is because the data that tech companies use to train artificial intelligence must be disclosed.

There is hardly anything more annoying than a slow or unstable internet connection. However, this happens all the time, especially when it comes to WiFi. We show you some tools to improve your WiFi.
Constant Internet access – a luxury that we no longer want to do without these days. However, frustration arises from time to time, especially when it comes to WLAN. Poor reception, a slow connection and other disruptive factors sometimes make surfing the Internet a test of patience.
Slow WLAN is particularly noticeable with large amounts of data
Slow WiFi is particularly noticeable when you want to download large files or stream films and series. Even people who like to play online games know the problem well.
However, the WiFi connection can be improved here and there. Even if the end device does not offer an extra socket for an external LAN cable. Because online tools can help to improve Internet reception.
Improve Wi-Fi: Online tools can improve reception
So that you don’t have to worry about an unstable internet connection as often in the future, we have put together some online tools for you that can help you to improve your WiFi reception.
WLAN card leads to the best reception
The online tool Ekahau Heatmapper shows you on a map where you have the best WiFi reception in your apartment or house.
After installing the program, you simply walk through your four walls and test your connection. The tool helps you to find the perfect position for your router and end devices.
Improve WiFi with a different radio channel
WiFi analysis tools such as Homedale, WiFi-Scanner or Xirrus WiFi Inspector can help you to check whether your wireless network and that of your neighbor overlap.
You can then select another channel that is as far away as possible in your router menu. This should make your WiFi connection faster.
Read WLAN information
the tools WirelessNetView gives you the opportunity to call up information about available WLANs. The program runs in the background and monitors the wireless networks around you. The tool also shows you all active wireless networks and their signal strength.
Turn off the pre-installed WiFi throttle
computer picture offers one WLAN-Booster with which your notebook can surf faster. The program changes the speed level of the wireless adapter chip in the mobile device so that it works at the highest level when the notebook is running on battery power. This is less energy-efficient, but faster.
Overview of network connections
the tools Acrylic WiFi Home helps you get an overview of the speed and security of multiple WiFi networks. To do this, you can mark a wireless access point in the program. Several color bar ratings then light up.
Improving WLAN: This is how you turn your PC into a router
Sometimes the WiFi connection slows down or fails completely because the distance between the router and the end device is too great. So-called repeaters can help to avoid this. These are WiFi extension bridges that increase the range of the wireless signal.
There is also the option of using your own PC as a WLAN Internet access point. Your Windows operating system shares the Internet connection with on-board resources via the command line.
It’s even easier with Connectify Hotspot: The tool has a graphical interface and creates a hotspot using an existing LAN or WLAN Internet connection.
The program works in a similar way MyPublicWifi. Although the tool is less common, it does not display ads in the user interface.

Improve WiFi with Internet Speed Test
If the WLAN is slow, it can also be caused by your provider. To be on the safe side, it is advisable to first carry out a speed test of your internet connection.
With a DSL speed test you can find out how fast your data is transmitted over the corresponding Internet line. If you find that your data transfer is slower than promised, you should contact your provider.
Researchers from Switzerland have apparently made a breakthrough. Because they developed a new type of solar power plant that can generate both hydrogen, heat and oxygen.
When it comes to the energy sources of the future, sustainable options are increasingly taking over. Against the background of climate change, this also seems necessary. In addition to solar systems and wind turbines, experts also see hydrogen as a future energy supplier. Researchers at the EPFL University in Switzerland have now made a breakthrough.
Because even if the combustion of hydrogen usually only produces water and oxygen, sustainable production continues to be complicated. With their new approach, the university team has now demonstrated that the solution could lie in the sun.
Solar power plant produces hydrogen by pooling energy
To do this, they developed a system that resembles a satellite dish and works in a similar way. During the day the sun shines on the bowl. This, in turn, bundles the energy and concentrates it on a small reactor that converts water into hydrogen, oxygen and heat. The bundling of the solar radiation meanwhile enables a thousandfold concentration.
A first pilot system achieved an output of one kilowatt. A further developed prototype already two kilowatts. Sophia Haussener, Head of the Laboratory for Science and Technology of Renewable Energies, speaks of a very high degree of efficiency without going into further detail.

Occurring oxygen as a by-product for the medical industry
The team sucked off the accumulating oxygen and used it further. Because producers often see this as a waste product – even if the medical industry were a possible customer. The system is suitable for industrial, commercial or private use.
The solar reactor could be used, for example, to generate enough energy for the heating and hot water supply of entire neighborhoods. With the current prototype, an output of around half a kilogram of hydrogen per day is possible. Extrapolated, this is enough to supply 1.5 hydrogen vehicles with fuel for one year. A four-person household in Switzerland could use it to heat for six months.
