It would be a very odd house where solar gain happens that quickly.

Modern, perhaps?

Large area of bifolds and 3 roof lights, all South facing, does trap a
lot of heat very quickly on a sunny day.

Quicker than a thermostat can shut the heating down?

Of course no matter what the starting temperature, solar gain can make
that room too hot quite quickly. Best to get some blinds, etc.
