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

Question: I’ve recently contacted another solar installer who asked me why we’re not adding 2-3 solar thermal panels to support the air-to-water heat pump. I originally thought that usually you either go with photovoltaic panels or solar thermal, and I had in mind that the additional costs and effort wouldn’t be worth the savings. However, he said it wouldn’t be that expensive.
Does anyone have experience with this combination? It’s quite rare to see this on residential roofs...

I would only install photovoltaic panels. No additional system. In summer, you already have enough electricity to heat the water, and in winter, the water stays cold anyway. Solar thermal also generates energy exactly when the photovoltaic panels do. True, good point. Thanks!

So in this case, it’s less about supporting the air-to-water heat pump and more about boosting his own wallet 🙂
