HubiTrubi4024 Mar 2026 13:37Hello everyone,
I have now gathered several quotes for a photovoltaic system and have settled on a regional provider. They gave me the best overall impression and offered the fairest price with the best components. The 8 kW system with a 10 kW battery storage costs 17,500 euros. At first, that was more expensive than I expected when I started looking at this somewhat naively. By now, I have seen everything from 5 kW peak systems with 4 kW storage in a similar price range up to 10 kW with 10 kW storage for around 25,000 euros, a mix of regional and nationwide providers. So I think the price is reasonable. The 8 kW system is planned on the south side, and now there is an option to also install panels on a dormer facing north. That would bring the total to just over 11 kW for 21,000 euros. Do you think that is worth it? I am a bit hesitant to spend the additional 4,500 euros for electricity demand that I currently do not have (my current electricity consumption is about 2,500 kWh/year), and I also already have a small balcony system. I might replace my heating with a heat pump in the future, but that is not certain yet, and maybe someday an electric car will come, but that is not planned in the next few years. So my question is: would you recommend the smaller system or should I go for the larger one (especially since I have a few other projects where I could use the money)?
What is your opinion about the structural inspection? The quotes say there will be a visual inspection. I assume that will not hold up as a proper structural engineering report. On the other hand, my roof on the south side has almost a 40-degree pitch and was built in the mid-1990s, so hopefully it is strong enough. I don’t know anyone in my circle who has asked a structural engineer for this, but you never know. What do you think? On the north side, I actually feel it might be more critical—firstly, because snow tends to stay longer there (if it ever falls), and secondly because the dormer only has about a 15-degree pitch.
I look forward to your opinions. By the way, I live near the Swiss border, so prices are correspondingly higher here.

Proud price, but even without knowing the components, it is still too high.
Currently, around 1000-1200€ per kWp (kilowatt peak) is normal; it can be lower with own labor.
There is a forum where you can have offers evaluated, but unfortunately, naming names is not allowed. However, search for it—at this scale, you should definitely be able to get a system with storage for under 15k without much effort.

Siedler3424 Mar 2026 20:58Last year, we spent about €22,000 for nearly 8 kWp (kilowatt peak).
We initially considered doing it with our own company (our employees are capable), but it didn’t turn out to be any cheaper, so someone else handled the paperwork. The price is reasonable. Somehow, there are always people who claim it can be done for half the cost. But as mentioned above, not when you factor in the time required for everything.
I would recommend going with the smaller size. Feeding energy back into the grid is not worth it, and in winter the system produces very little anyway. You won’t be able to run the heat pump with it. You probably won’t recover the additional costs.

Here is experience from Berlin,
Household electricity consumption about 2500 kWh per year,
Heat pump electricity consumption about 2500 kWh per year,
Photovoltaic system 13.2 kWp with 9.6 kWh storage,
We save two-thirds of the electricity consumption, only pay for one-third.
Only one meter instead of two.
From March to October we could even supply an electric car.
We paid 19,000 euros two years ago.

No one just shows up around the corner.
My own system: 13.8 kWp hip roof with a 12 kW battery storage for 13,200 euros.
And at a colleague's place: 17.8 kWp with a 10 kW battery storage for 17,500 euros.
But those who don’t inform themselves end up paying more, just like the Enpal customers who simply don’t know any better.
Here are some current average prices:
Postal code first, followed by the price per kWp

MachsSelbst25 Mar 2026 08:17Adding an extra 3 kWp facing north for 4,500 EUR is really pointless. It’s just as pointless to base the company’s price on any kind of module purchase cost alone, without considering the installation and connection work.
This kind of price haggling is often unreasonable; if the company, which also has to pay employees, is too expensive, then you have to do it yourself. Some people also tend to forget that when they work for clients, they charge hourly rates starting from 200 EUR. It’s about much more than just materials and wages...
But 8 kWp or even 11 kWp for a consumption of 2,500 kWh/year is quite a lot. Please keep in mind that feed-in tariffs are currently under discussion and, according to the CDU, may be completely eliminated. Then it only makes sense for the electricity you consume yourself. At 35 cents/kWh, with your consumption and 100% self-use, that would be just under 1,000 EUR per year.
Install the 8 kWp system, that will be enough. You won’t be charging your electric car to 100% every day in summer, and in winter it will support the heat pump, assuming you get one eventually. You shouldn’t expect anything from the north side in winter anyway, and even on the south side, yields drop to 10-20% of midsummer levels...
