How they handle the components would be critical on a front house installation.
Having panels on the front roof wouldn’t make me necessarily walk away from a house, depending on how diligently they were installed in consideration of the aesthetics of the house, could seriously impact curb appeal.
Done cleanly, and you won’t really see much more than the panels, not so cleanly and you see funny looking conduit runs that will just make it look haphazard.
That said, if electrical projections hit the 30%+ they’ve been saying in the next few years and we have weather like today, no one may care if they walk into your nice AC cooled 75 degree Fullerton home and you tack an electrical bill up next to thermostat saying $1.77.
