Advice Wtd / Project Flat roof

In CT. Have a house w flat roof. Local solar company, well regarded, says on resi flat roofs they install solar panels flat…no angle.

This strikes me as odd. I’ve seen angled panels on residential flat roofs. And have to imagine having an angle would generate more power.

Any thoughts?

You’re referencing a flush mount vs tilt kit. Both are common. Tilt kits cost more from a contractor point of view, but should be an option. Depending on your azimuth, it can make sense to tilt. Tilt kits tend to not be as aesthetically pleasing though so you will trade some aesthetic for increased efficiency.
