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

The basement is ideal for the battery, mainly because of the constant temperatures throughout the year. That’s where mine is located as well. I wouldn’t keep it in the garage, as it can get very cold there during winter. BYD specifies that the battery can withstand -10°C (14°F) ... we will insulate it further.

BYD specifies that the storage can withstand -10 degrees…Correct, "withstand". If it gets colder, do you dismantle it or rely on the insulation effect?By the way, BYD's statement comes with the footnote that "performance is reduced from -10°C (14°F) to +5°C (41°F)" – whatever that means in detail.

If necessary, install frost protection. Although I’m not sure to what extent it counts as a heating appliance.Heating appliances are defined here as oil, gas, pellet (or firewood, etc.) systems. Heat pumps or frost protection devices (electric) are not considered heating appliances.
