Photovoltaic system: Costs, saving potential? - Experiences?

Yes, partially. The corner on the carport remained clear due to self-shading by the house. We would still need to leave space on the main compartment to access the outdoor unit of the air conditioning for maintenance work. But this also works for us.

Our system was put into operation today. 9.72 kWp east/west on flat roof and carport mounted. SMA inverter with IBC solar modules and substructure. Net 12,500€ complete.

Was there anything additional included to justify the price? Good 2000€ too expensive, net, IMO

When the sun shines, it is around 27°C in the living room alone due to the sun (yesterday).

Out of pure interest, what percentage of south-facing window area in relation to the living area do you have in your living room?

Purely out of interest, what percentage of south-facing window area do you have in relation to the living area in your living room?

To the south, a double-leaf terrace access and a floor-to-ceiling window of normal width. Then another double-leaf terrace access to the west. The room has 48.5m2.

Was there anything extra included that justifies the price? Easily 2000€ too expensive, net, in my opinion

How would you know that, the region alone makes a 50% difference.

Where do you want to know that from, just the region makes a 50% difference.

Apart from the fact that there are supraregional providers, one can get a very good cross-state impression of what is usual in the market and what is not.

And if a craftsman receives €2000 more for one day of work, that is by no means (completely) explainable by regional fluctuation.
