Photovoltaic panel installation technical specifications

These specifications were created with certain assumptions about the house and the proposed solar energy system. They are designed for builders constructing single family homes with pitched roofs, which offer adequate. . Builders should use EPA’s online RERH SSAT to demonstrate that each proposed system site location meets a minimum solar resource potential. EPA has developed an online site. . EPA has developed the following RERH specification as an educational resource for interested builders. EPA does not conduct third-party verification of the site data or the online site assessment results, or verify whether the home. . The builder should install a 1” metal conduit from the designated inverter location to the main service panel where the system is intended to be tied into the home’s electrical service.. [pdf]
