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

Is it because only the model is available, or what is the reason? It doesn’t really make sense.Are you referring to me? I don’t understand the context 😎

The overview gets lost on mobile... A 17kW inverter for a 13kWp generator doesn’t make sense, but nowadays inverters are hard to come by as well. You say a larger inverter is needed, but on the other hand, it’s too big? We also plan to build a carport and probably install photovoltaic modules there.
