   This problem was solved by child inventor years ago. He designed a roof that consisted of angled panels alternating black and white. The angles (determined by latitude) were selected so that the white panels were exposed to direct sunlight when the sun was high in the sky during summer, and the black panels were exposed to direct sunlight when the sun was low in the sky during winter.He won an award, but I’ve never seen his idea implemented anywhere.
