Air-to-water heat pump with solar

Hello, we are currently planning a new building made of formwork blocks (isorast/varianthaus etc.). It will have 165 sqm with underfloor heating throughout. Now to my question: I would like to use an air-water heat pump. Which models can be combined with a solar thermal system? My concern is that in summer I won’t need heating, only hot water, and in winter I will definitely need the heating. Which system would be best for that? The buffer tank for the heating does not need to be very large, hot water around 300 liters.

The extra cost you have to pay for the storage, collectors, and control system can also be invested in 20-30 years of hot water in summer heated only by the heat pump... it is definitely cheaper...
