On the ICON Solar House, the ridge of the roof is pulled towards the north, which expands the surface area on the southern side. At the same time, the ridge is raised so that the solar panel roof is angled perfectly for maximum sun exposure during the winter, when energy demand is at its peak. In Minnesota, located in the north central section of the US, an angle of 35 degrees to 45 degrees is usually considered ideal for solar collection during the winter. ADS
