Hello dear forum,
maybe some of you have faced the same situation or have the same question.
I couldn’t find anything clear on the internet regarding this.
Here is the initial situation:
- Solid brick house built in 1970
- Heating system with storage heaters running on 100% green electricity tariff, plus a tiled stove
- Roof insulated with insulation between rafters, attic insulated with XPS boards, plastic double-glazed windows,
so definitely not a modern insulation standard
- Annual energy consumption – daytime electricity (peak) 2,500 kWh (2,500 kWh) – nighttime electricity (off-peak) 7,400 kWh (7,400 kWh)
- Most of the living areas are heated with the tiled stove
In the coming years, the roof tiles will need to be replaced. From what I understand, in Baden-Württemberg, I would then have to install a photovoltaic system.
This raises the following questions for me:
- How am I supposed to finance this with the current high interest rates? The monthly cost, including the mortgage, would simply be too high.
- We can’t afford a complete renovation (insulation, new windows, heat pump, etc.).
- As far as I know, you can’t power storage heaters with a photovoltaic system, even with a battery storage, because they consume too much electricity. Plus, in winter, when we need the most electricity, too little electricity is generated...
- So, at most, a small photovoltaic system would make sense to cover our daytime consumption (about 2,500 kWh (2,500 kWh) per year).
- I have concluded that such a system is not yet economically viable for us, especially with the high purchase costs and high interest rates. Is it possible to avoid the photovoltaic installation requirement if you don’t have the financial means and only need to replace your roof tiles?
Has anyone been in a similar situation? What approach did you take or what are your plans?
Thank you very much!

xMisterDx18 Feb 2024 23:23Unfair hardship applies to the 80-year-old widow who has lived in the house for 50 years and now has to sell it because she cannot even get a 5,000 EUR (about 5,400 USD) loan. She also wouldn’t be able to afford the installments.
In this case, the buyer simply miscalculated by not anticipating rising interest rates.
Choose the smallest system that meets the requirements and definitely skip the battery storage.
An acquaintance recently installed a 4.2 kWp solar system with a 5 kWh (approximately 1.4 kWh) battery and a new meter cabinet for 19,500 EUR (about 21,000 USD).
He won’t recover that money in 25 years...
And I couldn’t sleep one night because I was laughing so hard...

Here, a buyer simply miscalculated because they did not anticipate rising interest rates. Miscalculated? Perhaps. But a refused loan approval is explicitly considered unreasonable hardship by the state government of Baden-Württemberg, regardless of whether the person is 80 or 30 years old.

And then we come back to the costs — suddenly installing a 25 kWp system and receiving or having to finance an offer of €40,000 (about $42,500) can easily cause financing to fail.

You’re contradicting yourself a bit. The photovoltaic mandate has actually been in place for almost four years, and in a democracy, such things don’t just appear out of nowhere. So either you haven’t purchased in the last few years or you haven’t been paying attention. And if you bought before the photovoltaic mandate, your chance of getting an additional loan back then would have been less than 1%. For existing buildings, it was decided at the beginning of 2022 and has been in effect since January 1, 2023, and by then there was no longer any financing available at 1%.

Here, a buyer simply miscalculated because they did not expect rising interest rates.Such statements can only come from high earners who have no idea how much even rundown properties cost in the Stuttgart area. It is then quite normal that there is no room for an additional 15,000–20,000 € (approximately 16,000–21,000 USD).The obligation to install applies only in the case of major roof renovation. In a few years, there will probably be court rulings on whether a one-to-one replacement of the roof tiles is sufficient. But if I am going to redo the roof anyway, then I do it completely with insulation, underlay, and new battens.
The question is who will inspect it if there is no building permit / planning permission.
60% of the suitable roof area must be covered, which in the best case means under 10 kW, costing around €10,000 (approximately $11,000) if the roof is already being done, and pays off very quickly. But I understand if someone does not want to take out a new loan. I didn’t take one either in a similar situation with 1% interest.

The obligation to install applies only during major roof renovations. In a few years, there will probably be rulings on whether a direct 1:1 replacement of the roof panels is sufficient.The guideline explicitly states "and always when the roof waterproofing or the roof covering is completely renewed." This is a clear requirement that leaves little room for debate. It can also be found in FAQs and similar documents.Similar topics
