Is the installation disruptive?

Minimally. 1-2 days of work on the roof. Brief electricity interruption (30-60 min) for consumer unit connection. No internal work except inverter mounting (garage/utility). Less disruptive than painting a room.

Do I need to be home?

For part of it — the electrician needs access to your consumer unit (usually indoors). You also need to provide your WiFi password for monitoring setup. No need to take the whole day off.
