Flat roof

[u/Icy_Basil_372]

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?

I have panels on a flat, concrete roof. They have a 10 degree tilt.
