Roof characteristics for integrated solar collection in dwellings of Real-Estate developments in Concepción, Chile
This paper presents an analysis of the roofs of recently built single-family homes in Concepción, Chile in order to identify their potential for integrated solar energy collection. It seeks to promote the installation of domestic renewable energy systems in the face of growing residential energy con...

This paper presents an analysis of the roofs of recently built single-family homes in Concepción, Chile in order to identify their potential for integrated solar energy collection. It seeks to promote the installation of domestic renewable energy systems in the face of growing residential energy consumption. The study comprises 2,139 homes in the district, all of which are part of residential developments built since 2006 (68.28% of total homes built over this period). The houses all have pitched roofs with a mean azimuth of 37.48°.
