ᐅ Underfloor heating with an air-to-water heat pump. House gets too warm when the sun is shining.

Hello everyone,
I have a general question.
We moved into our new build four months ago. The living area on the ground floor has three large floor-to-ceiling windows facing south. We have underfloor heating and an air-to-water heat pump.
It provides a really comfortable temperature inside the house, but we have a problem – whenever the sun is shining in winter, even if it’s -2°C (28°F) outside, the temperature suddenly rises to 24°C (75°F) in the living room. It gets uncomfortably warm in here, and the underfloor heating can’t be turned down quickly.
Should we assume that the large floor-to-ceiling windows are responsible for the heat gain? A photo of the south-facing side of the house is attached.
What would you do – always lower all the blinds as soon as sunlight is forecast? That seems quite annoying...
We have motorized blinds controlled by Somfy. Would you consider buying a sensor that automatically lowers the blinds at a certain temperature?
Thanks in advance for your replies.

Do you have a photo of your sunshade ready?
Aren't there already fairly weather-resistant awnings nowadays that can perhaps even withstand rain (nanotechnology or something)?
Because I don’t find a fixed overhanging roof, like you often see on urban villas, very appealing, and it also reduces the heat energy coming in to warm the house, doesn’t it? I don’t have one handy at the moment, but they are currently quite common anthracite-colored aluminum canopies with glass and an integrated retractable awning underneath. If you search for "terrace canopy anthracite aluminum glass," you’ll find various examples; ours, for instance, is from Venomenaal, but there are thousands of suppliers offering almost the same systems. These are usually modular systems, which can also be expanded into an unheated winter garden (but I’m not a fan of that). Whether it fits the house aesthetically obviously depends on the building itself. If the house has a fairly clean, modern design, I usually find such canopies to be an aesthetic upgrade.
As for awnings without a canopy... honestly, I don’t know. However, I assume that no matter how they are coated, once an awning is rolled up wet, you’re likely to have issues with mold.

Yes, something like that is really essential if you have south-facing windows. Or alternatively, external venetian blinds, although I always associate those with office or school buildings...How do you keep the glass of your aluminum and glass canopy as clean as possible?
