Air-water heat pump current consumption and data

I paid €1,099 per kWp. We can perhaps forgive that one per mille deviation, ... after all, we are among friends

You derive this from your offer? Is that your data basis, which is valid for all of Germany? Seriously?

No, I can also provide alternative offers. Moreover, it is an offer valid nationwide in Germany, not from a small company.
And if you want even more "data basis," I recommend you read up well here in the forum. They will simply laugh at you with the Google price. It is like a furniture price. Write 1,500 on it and pay only 1,100.

Okay then I will get a quote from further away. I have 3 regional offers here, all of which are rather over 1500 euros per kwp, except the one I already mentioned with just under 1300 euros. The companies probably think that whoever pays over 1000 euros for the m2 of building land can also spend a bit more on photovoltaics...

The price differences between local and other solar installers who were also local are certainly not insignificant. That's when you first realize how they want to rip you off. Although he was only a broker and would have then sent out a photovoltaic crew.

Since the topic often comes up regarding solar yield and what color the terrace slabs should be

3 measurements on the topic

1x tiles inside the house in anthracite behind the window



Terrace light gray



And paving stones in gray



Fortunately, we decided on light terrace slabs back then. You can no longer stand on the tiles inside the house because they get so hot.

Outside it is about 15 degrees.

And the grill is running

We therefore chose light gray and not anthracite outside. But what you are measuring there is nothing compared to midsummer. The heating is still off. At night, it was still a bit below zero. However, the solar yield is so high that the venetian blinds are now down and the temperature in the house remains constant. During the day, it is even too warm on the upper floor because the blinds are up. But the children don't mind.
