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

I tried to upload the datasheet as a PDF, but the forum rejects it because of the file extension. Then just upload the German datasheet. The inverter can also be purchased normally within Germany.

Best regards, EliasWe are paying €16,500 for the G8 system including power optimizers, fully black, plus installation, connection, and a free inspection after one year. The system size is 13.26 kWp. However, the offer and acceptance are from last year.

TomTom197925 Apr 2022 08:03After more than 8 years, the admin actually deleted my account...
He didn’t give any reason, but I suspect it’s because I said I would inquire in the xx forum...
You get a 10-day ban for asking for pictures of a clover meadow in a garden subforum... Apparently, that was off-topic.
And the very best part was receiving writing bans because I mentioned a technical forum in private messages. By the way, that private message was several years old.
