Bauexperte26 Mar 2012 11:18A friendly hello to the users/readers of the house construction forum,
Over the weekend, I attended the Bau- & Wohnträume exhibition in Pulheim. There, I got to know one of the winning products from the competition mentioned in the subject line, organized by the state of Baden-Württemberg.
But first: What is an "Übermorgenmacher"?
"Übermorgenmacher" live in Baden-Württemberg, are at least 16 years old, and are working—professionally or privately—on an exciting future-oriented project. Usually, they are individuals. Some "Übermorgenmacher" work together in small groups on a shared project.
Übermorgenmacher focus on technology, science, or research, work in medicine, manage projects in the social sector or ecology, look for improvements in everyday life, or work to optimize education in our country. In short: They work precisely where the future is developed and the world of the day after tomorrow is shaped. They do this either professionally or possibly in their free time.
One of this year’s winners is Bernd Sauer. He developed the self-sufficient power system AZUR INDEPENDA, setting the course for generating and storing environmentally clean electricity for personal use.
Introduced in early June 2011 at the world’s leading trade fair Intersolar in Munich, the intelligent self-sufficient power system enables private households as well as small and medium-sized enterprises to shift from being dependent consumers to nearly independent energy producers.
In this intelligent power system, solar power is distributed within the home by a device called an energy manager, which is computer-controlled. Depending on current demand, electricity is automatically used immediately, stored (in a special solar storage system in the basement), or fed into the public grid if there is excess production. For the homeowner, this means: they always have electricity and receive up to 80 percent of their electricity needs from their photovoltaic system on their own roof. This relieves the power grid and the environment, reduces CO₂ emissions, and saves money.

Example:
You invest, for example, approximately €30,000.00 (net retail price of €30,000.00 including all ancillary costs such as mounting structures, remuneration from the Renewable Energy Act, as well as maintenance contract and interest) for the plant size L (6.345 kWp capacity).
Over 24 years, you save a total of around €55,000.00** on electricity costs. Despite the investment, you make around €30,000 across the term.
You can conveniently arrange financing through your house bank, your home savings bank, or through a KfW loan.
**The calculation example is based on an electricity price of 0.26 cents/kWh, an annual electricity price increase of 6% (including 2% inflation), an interest rate of 5%, a self-consumption rate of 80%, a maintenance contract of 250 euros per year, and an electricity yield of 950 kWh/kWp/year.
Renewable Energy Act remuneration comparison for self-consumption
With 100% grid feed-in, the Renewable Energy Act rate is 24.43 cents.
With 70% grid feed-in and 30% self-consumption:
26 cents for the saved electricity price
+ 8.05 cents Renewable Energy Act remuneration for self-consumption
= 34.05 cents.
Your advantage with self-consumption compared to
100% grid feed-in (24.43 cents) is 9.62 cents.
With 20% grid feed-in and 80% self-consumption:
26 cents for the saved electricity price
+ 12.43 cents Renewable Energy Act remuneration for self-consumption
= 38.43 cents.
Your advantage with self-consumption compared to
100% grid feed-in (24.43 cents) is 14 cents.
As of 2012. All cent values per kWh.
Best regards

A valuable piece of information!

The savings are significantly higher when considering the overall energy balance, because photovoltaic panels, when installed with ventilated mounting, passively reduce summer cooling loads. This aspect is often overlooked in the overall energy balance and even in energy-saving regulations, where summer thermal protection tends to be neglected!
...
For the homeowner, this means: they always have electricity and receive up to 80 percent of their electricity needs from their photovoltaic system installed on their own roof. This eases the load on the power grids and the environment, reduces CO₂ emissions, and saves money.

Micha&Dany27 Mar 2012 06:33Hello building expert!
The special compensation for self-consumed electricity is currently being canceled... unfortunately.
Furthermore, the photovoltaic system operator remains obliged to consume a certain portion of the electricity themselves – as far as I know, only 70% of the electricity produced is even compensated anymore.
I’m not in the mood to recalculate your figures with the new regulations – photovoltaics will still be worthwhile since prices continue to fall. The higher the own daytime electricity consumption (for example, due to a heat pump), the better the return on the system.
Are storage systems already worthwhile (for private users)?
In my opinion, they are as much worth it (good or bad) as solar thermal systems :p (greetings to the €uro).
When will the new regulations take effect? Well, that remains to be seen. Initially, March 9, 2012 was considered, then April 1 – but this regulation will most likely come into effect anyway.
Well, that’s my two cents 😀
Best regards

...Is it already worthwhile to invest in storage systems (for private individuals)??? In my opinion, it is just as worthwhile (or not) as a solar thermal system :p (Greetings to €uro) Thanks for the greetings 🙂 I share this view, although more towards “not worthwhile.” 😉 The chase for so-called “freebies” has caused some projects to become financially unviable without the future owner even realizing it. 😉Best regards

Bauexperte27 Mar 2012 12:27Hello Micha,
It is at least a start and gives hope, due to competitive pressure, that more storage media will be available by 2021. Sometimes I could really get frustrated with those bureaucrats in Brussels... you know what I mean... 🙄
Kind regards

Micha&Dany27 Mar 2012 15:22Hello Bauexperte
Yes, that would please me. Personally, I believe a mainly decentralized energy supply with energy storage is the best way to complete the energy transition.
Decentralized energy storage for a neighborhood or a street (or however you want to call it) is more cost-effective than batteries in the basement – but the folks working on storage still have some homework to do 😀
By 2021? Could happen!
Oh yes – I’m with you!! And then we’ll continue in Berlin!! :p
Regards
Micha 😎
