ᐅ Solar power system quote for our single-family home

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

To be honest, I don’t find the modules ugly.
On anthracite-colored roofs, which are currently popular, I think the modules look okay. But on red roofs like ours, they look really awful. However, the appearance has to take a back seat to the function.

Here is my roof. Nothing more was possible, except for the garage, but it is somewhat shaded by the house.

There have even been red modules. However, they never really caught on. They are only used for churches or heritage-protected buildings.

@Fuchur : THAT makes me SO happy. You saved my evening! 🙂

Respect, that looks very good!

This is how true self-sufficiency works... 😎

Were they cheaper in bulk? (-:

It looks good on your place; I have a red roof on a carefully designed Tuscan-style dream home, so it doesn’t quite have the same appeal for me.

But it can always get worse: on a flat roof, the panels just don’t look great when mounted like that.

You don’t have battery storage, right? But I wouldn’t want it in the basement either… I’m glad to have it in the garage.
