I've never considered my 70s semi particularly large, and managed
to accommodate an array of 3,64 kWp. I think that you may be
underestimating actual roof sizes.

That is based upon the dimensions of three different houses I have lived
in or owned and for which I have drawings. Only one - a five bedroom
house - would have been able to take a full 4kWp array on a single roof.
