JIS C 8956:2011 PDF Download

The JIS C 8956:2011 standard specifies the guidelines for designing and installing residential roof-mounted photovoltaic power generating systems. This standard specifically applies to arrays with an output of less than 20 kW, where the photovoltaic array is mounted on a flat or sloping roof. The standard specifically focuses on crystal-array systems and excludes other types of arrays such as concentrating arrays, tracking arrays, sunlight and solar heat hybrid type arrays, arrays serving as building materials, and arrays comprised of AC modules. The purpose of this standard is to ensure safe and reliable installation and structural design practices for residential photovoltaic arrays.
