We ask ourselves, is the 5.04 kWp sufficient?
Sufficient for what exactly?
To generate the same amount of electricity that the household consumes? - No.
Google PVGIS, then you can determine the expected yield of the system. I'll roughly say, oriented south and unshaded, you get about 900-1000 kWh per kWp of generator capacity per year. Roughly.
To your expected household electricity consumption of 4500 kWh, add the heat pump, let's say 3000 kWh.
Your offer is somewhat acceptable with a tendency to be expensive.
The question is, in the new building, what the solar installer intends to do at the meter cabinet or what is meant by the position.
Whether the allocation of North/East makes sense for you, they can also tell you there. The rules of stringing are not my forte, but with 5x360W facing north, not much will come out or the string could fail. But the experts over there know that much better.
