The house appears to be new construction as evident by the resets still on the foundation, the empty paint buckets and all of the wood looks new not weathered and repainted. The horizontal bars are probably for a solar install
But those gutters where they are mounted are less than useless for anything more than a light drizzle. They should have been mounted on at least a 2inch and possibly a 3 inch stand off and a couple inches higher. Sub-contractors don't care if the gutters do anything they get paid by the job.
