You are drawing that conclusion from your quote? Is that your data basis that applies to all of Germany? Seriously?No, I can also provide alternative quotes. This is a nationwide offer, not from a small company. And if you want an even bigger "data basis," I recommend you read thoroughly here in the forum. They will just laugh at you with the Google price. It’s like a furniture price: you write down 1,500 and pay only 1,100.
Okay, then I will get a quote from a company further away. I have three local offers here, and they all tend to be above 1500 euros per kWp, except for the one I already mentioned at just under 1300 euros. The companies probably think that if someone pays over 1000 euros per square meter (m2) for building land, they can also spend a bit more on photovoltaic systems...

The companies probably assume that anyone paying over 1000 euros per square meter (approximately 93 square feet) for building land can afford to spend a bit more on a photovoltaic system... The price differences between local and other solar installers who were also local are quite noticeable. That’s when you realize how they try to take advantage of you. Although that one was only an intermediary and would have sent a photovoltaic crew out.
Since the topic often comes up regarding solar heat gain and the color of patio slabs
3 measurements on the subject
1x Anthracite tiles inside the house behind the window
Light gray terrace
And gray paving stones
Luckily, we chose light-colored patio slabs back then. The tiles inside the house get too hot to stand on.
Outside, the temperature is about 15°C (59°F).
And the grill is running

We also chose light gray instead of anthracite for the exterior for this reason.
But what you’re measuring there is nothing compared to midsummer.
The heating is still off. It was a little below zero at night.
However, the solar gain is so high that the external blinds are now lowered, and the indoor temperature remains stable.
During the day, it’s even too warm on the upper floor because the interior blinds are up. The kids don’t mind, though.
