Good morning,
Yesterday, we received a quote for a photovoltaic system. Our construction of the single-family house will start in October 2023 and is expected to be ready for occupancy in September 2024.
We have an annual electricity consumption of about 3000 kWh for our household, plus an unknown amount for the air-to-water heat pump (Weishaupt Biblock).
Our roof is oriented exactly south with a 25° pitch (gable roof). According to the calculation in the quote, the entire south roof is fully covered with modules (20 units), and the north roof is also equipped with 5 modules.
Attached you will find the details of the quote. The price is €20,900 net with battery storage and €15,900 net without storage.
What do you think of the offer? From what I understand in the discussions here on the forum, it is advisable to skip the battery storage. That would bring the cost to just under €16,000, which is a bit over €1,600 per kWp. That seems relatively expensive, doesn’t it?
Thank you very much in advance for your help.
Best regards,
Elias

There is a new offer update for our single-family house. I would like to ask for your help in evaluating this offer. The requirement given to the solar installer was to fully cover the roof and to skip the battery storage:
• Q-Cells Q-Peak ML G10 410 W
• 25 modules on the south and 25 modules on the north, total 20.50 kWp
The entire system, including installation and commissioning, is quoted at €32,000, which is €1,560 net per kWp. This seems quite normal for today’s market – neither cheap nor expensive, right?
Attached are the offer details and the roof layout. On the south side, the modules will be mounted flush on the roof (25° pitch) and on the north side they will be slightly elevated (21°).
Best regards!

Hello everyone,
there’s an update on the offer for our single-family house. I’d like to ask for your help in evaluating this proposal. The instruction to the solar installer was to fully cover the roof and to skip the battery storage:
• Q-Cells Q-Peak ML G10 410 W
• 25 modules facing south & 25 modules facing north, totaling 20.50 kWp
The total price including installation and commissioning is €32,000, which is €1,560 net per kWp. That seems quite normal nowadays – neither cheap nor expensive, right?
Attached are the offer details and the roof layout. On the south side, the modules will be mounted directly on the roof (25° roof pitch), and on the north side they will be slightly tilted on a mounting system (21°).
Regards! We got the G8+ with 340 W per module (13.26 kWp, completely black including frame and power optimizers) for €1,100 net. However, that offer dates back to August 2021. I find €1,560 to be almost borderline high, especially for this system size.

I’ll definitely try to negotiate. But 1,500 € net is unfortunately what you have to expect right now, isn’t it?N

If you are near Berlin, I could recommend one.

One doesn’t have capacity for installation but offered me the equipment (about 1100 € / kWp). However, I actually want a complete package. I’m still waiting for a third offer, so I have some hope...Otherwise, several companies simply declined or told me to inquire again next year.

But €1500 net is unfortunately what you have to expect at the moment, right? Do you have to? I can’t fully assess the current situation, which also varies regionally. I already thought my system, ordered two years ago per kWp, was "too expensive." But a simple pitched roof with a relatively large system only has one-time costs. In my opinion: outrageous. But no matter when the system pays off, I would probably still do it (there were serious forecasts predicting 50–55 cents per kWh). Then this solar PV system, even if not already ecological, looks different economically as well.
