ᐅ Experiences with Satellite Dish Installation at the Site?

We are building a new house and are uncertain about how to mount the satellite dish. Mounting it on the south-east facing shed roof is not possible, as it is completely covered with a photovoltaic system. The satellite dish should be as inconspicuous as possible (e.g., a Selfsat flat antenna).
Is it possible to install it on the house wall facing the garage?

Yes, it should not be a problem...

Astra is at 19.2 degrees east. You might need a wall mount with a longer arm, as the dish is almost perpendicular to the wall.
