In diesem Video untersuche ich die Erhöhung der Einspeisegrenze von 600 auf 800 Watt, das mit dem Solarpaket 1 geplant ist. Mit diesem Video möchte ich zeigen, dass die Leistungssteigerung für gängige Haushaltsgeräte wie Wasserkocher oder Waschmaschine nur geringe finanzielle Vorteile bringt. Der Fokus liegt auf der Einschätzung, ob dies für den durchschnittlichen Verbraucher relevant ist. Ich verwende zudem meinen Eigenverbrauchsimulator, um potenzielle Gewinne zu berechnen. Schaut gerne rein, um alle Details zu erfahren. Daumen hoch oder runter nicht vergessen!

    Video mit den Ermittlungen der Lastgänge:

    Hello. Here is Sebastian again. Solar Package 1, which was launched by the German federal government, includes, among other things, increasing the feed-in limit from 600 to 800 watts for balcony power plants and plug-in solar devices. I would also like to explain why I think this is irrelevant for us average consumers

    … I would like to show that with this video in a hopefully easy-to-understand way. And so that I can continue watching TV in peace here in my hotel room, I’ll let an AI voice speak. What follows is a collection of common electricity consumers

    That are found in many households and can increase household consumption to more than 600 watts. The collection is divided into three areas. You will understand what the areas are all about in the course of this video. In the upper area there is a kettle, hairdryer, toaster, a coffee machine and a

    Water heater for hot water. These are devices that use a lot of electricity for a relatively short period of time. As an example, here is the consumption curve, i.e. performance over time, of the kettle and instantaneous water heater. The instantaneous water heater requires

    Significantly more power than the kettle and is usually on longer. The performance of the devices is deliberately not written down here, because for both devices it would only be what can be covered by a 600 watt inverter when the sun is shining. With an

    800 watt inverter that would be on top. So for the kettle 0.013 kWh, which would correspond to an added value of 0.39 cents. By the way, in the video we assume an electricity price of 30 cents per kilowatt hour! For the instantaneous water heater it is 0.033 kWh, which

    Would be an added value of one cent compared to the 600 watt inverter. If you blow dry your hair straight after showering in sunny weather, then boil water and then toast something, the consumption curve could look like this. Here again what a 600 watt inverter would contribute,

    And here the 800 watt added value. If you add the duration of the phases in which the household consumes more than 800 watts, we get 26 minutes. As a result of this behavior, the household would have an output of over 800 watts for 26 minutes, which

    Would correspond to a financial added value of 2.6 cents. Even if a completely crazy large family manages to synchronize themselves so that they shower, blow-dry and toast in a row at lunchtime, there is still the problem that the sun doesn’t shine every day. But more on that later. So here’s a thumbs down!

    Let’s move on to the middle area where the washing machine, dishwasher and stove are located. These devices usually run for a longer period of time and require a lot of energy over this period. However, they do not need the energy permanently. In a previous video I

    Created load profiles for the washing machine and dishwasher. The load profile of a washing machine describes the course of energy consumption over time during operation. Here is the load profile of a 60 degree wash cycle. It wasn’t easy to trace this because some phases were very short, around a minute,

    If at all. Here I’ll show how the 600 watt inverter could support us when the sun is shining. These small, orange areas here represent the added value of an 800 watt inverter. The washing machine jumps over 800 watts 6 times. The last four

    Escapes probably served to keep the water warm and are relatively short. If you now calculate the minutes of the individual phases over 800 watts and add them together, you get a total of 25 minutes. This means that the added value of an 800 watt inverter

    Compared to a 600 watt inverter for one wash cycle is around 0.0833 kWh, i.e. 2.5 cents. The situation is similar with the dishwasher. Here is the consumption curve I determined. However, tracing was a little easier because the phases are longer here. Here again is

    What the 600 watt inverter would contribute in sunshine and in orange the added value of the 800 watt inverter. The phases over 800 watts are a little longer here than that of the washing machine. In total, the dishwasher requires a power

    Of more than 800 watts for 35 minutes. That’s an added value of 0.116 kWh per wash cycle, or around 3.5 cents. Unfortunately I don’t have a consumption profile for the stove. The stove can use a lot more power, but the phases over 800 watts are probably

    Not much longer in total than with washing machines and dishwashers. It doesn’t seem intoxicating to me at all . So here’s a little thumbs down. I would give the thumbs up to the consumers in the bottom row – i.e. air conditioning,

    Heat pumps and electric cars that are charged at low power during the day. These consumers consume a lot of electricity over longer periods of time, so they get a lot of the 200 watts of additional power. However, I assume that most of us average consumers,

    Because we live in apartments, for example, do not own these consumers. By the way, one device that is a bit in between is the tumble dryer. I couldn’t really place it here and that’s why it’s hanging around in the middle. Its consumption profile is

    Solar-friendly, but the usage time is limited to a few hours per week. Anyone who knows this channel knows that I have written a self-consumption simulator that can calculate and therefore estimate a household’s own consumption using data from PVGIS – which is based, among other things, on historical weather data – and consumption profiles

    . The link to the short description of how the simulator works is in the description text. For the calculation examples that follow, I increased the consumption profile so that all of the solar power is consumed by myself, i.e. the self-consumption is equal to the total production of the system. One way to

    Imagine it is that there is a device that consumes 800 watts 24 hours a day. This is a scenario that will probably not occur in any normal household, but is the maximum that can be achieved from a balcony solar system, to say the least.

    If you take the historical data from 2020 for a place in central Germany – I used Kassel as an example – with a 1000 watt panel facing south at a 35 degree angle, you can

    Get around 1034 kWh per year with a 600 watt inverter . With an 800 watt inverter it would be 1112 kWh/year, an increase of 23.40 euros at an electricity price of 30 cents per kilowatt hour. If you have a panel with a 2 kW peak, you would get 1429

    KWh per year with a 600 watt inverter. The additional yield with an 800 watt inverter would be 270 kWh/year, i.e. 81 euros. Here are also the values ​​for 3 kWp and 4 kWp. Things only get really exciting with a solar output of 2 kW peak or more, but from then on it is

    No longer allowed – at least as far as plug-in solar devices are concerned – when Solar Package 1 comes into force. If you want to operate a balcony solar system with an output of more than 1000 watts, you need a relatively large amount of space or area. My guess is

    That most people who live in apartments don’t have this space. And the balcony power plants were actually made for these people. So, a special greeting goes to my very good friend Leander, who couldn’t come here to hike with me because of the train strike.

    Until the next video, I wish you a nice and sunny time and see you soon!

    1. Wenn man richtig geizig ist, was für mich eine Voraussetzung ist um sich eine Steckersolaranlage zu kaufen, sollte man unbedingt vermeiden, Zuviel des Ertrages zu verschenken. Ich habe einen gebrauchten Warmwasserspeicher (120L) mit einem Heizstab (600w) versehen, versorge damit 2 Waschmaschinen, Steuerung mittels 2 Fritz-Steckdosen. Mein Eigenverbrauch liegt bei 86%. Das bringt mir im Winter zwar kaum warmes Wasser, aber dafür verschenke ich da nichts.
