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

Elias_dee6 Jun 2022 17:52Okay, I can see this is really important to you :-)
Tomorrow, I will talk with my general contractor, who handles everything (except the photovoltaic system). I'm curious to hear what he says... By the way, we don’t need to plan for any windows. For cost reasons, we didn’t include any roof windows in our new build. And no satellite dish either. Also, no chimney (air-to-water heat pump, no fireplace). So really two completely free areas to plan – actually ideal for the purpose of installing photovoltaics...

@i_b_n_a_n : Even if there is no subsidy, maybe the charging station will become cheaper... or in the future we will have more money again 🙂
@Deliverer : Photos will definitely be coming! However, I’m still unsure about the metal roof. Unfortunately, I haven’t been able to find any experience reports or photos from others about it yet. My wife doesn’t want it because she’s worried it will look bad if the panels don’t cover the entire roof... :-/You could choose black panels with black frames. That’s what we did. They blend in very well with an anthracite-colored roof.

Elias_dee9 Jun 2022 22:33Another question in this context: I assume the snow guard needs to be installed higher if you have a photovoltaic system?
Otherwise, the snow would slide down over the panels and then, if the guard is installed directly at the edge, it would simply avalanche over the guard into the garden...
I need to talk to my main contractor to see if they can just enlarge the guards.

RotorMotor23 Jun 2022 10:53With a 14.4kWp system and a 10kW inverter, the system will inevitably be limited to below 70%.
Therefore, in my opinion, you can save almost €1000 on the Sunny Home Manager.
Depending on the orientation, it might also be worth considering a slightly larger inverter.

In my opinion, this makes the nearly €1000 for the Sunny Home Manager unnecessary.
Depending on the orientation, it might also be worth considering a slightly larger inverter. Silly question. Why is the system limited then? I always thought that any surplus would simply be fed into the grid.
