A gable solar attic fan mounts on the framing inside the attic behind an existing gable vent, with its solar panel on a cable outside, so the roof is never cut. It is the easier install where a gable vent already exists, and the panel can go wherever the sun is best. The vent’s louvers limit how much air gets out, so check that the vent’s open area suits the fan’s rated airflow.
