If you want to do low temperature heating, and solar is low temperature heating, you need very large area radiators.

Hydronic floors are very large area radiators, and when they are made correctly they are silent.

Forced air does not work well with lower feed temperatures, unless the air handler and ducting system and blower are all designed specifically for low temperature heating. This would mean a much larger than typical surface area in the air handler, duct work that is capable of quietly handling continuous air circulation, and a blower that is very high efficiency (ECM) and is able to adjust it's speed over a wide range, because it will need to run just about constantly.
