Location of Breaker or slot for future breaker in electrical service panel.Location of panel or blocking for future mounting of PV system components.
Location and number of necessary pull boxes in line with each conduit run.Length of conduit from the designated array location to the designated inverter location.Electrical service panel location and dedicated circuit breaker slots.The diagram should have sufficient detail to clearly identify: In addition, the homeowner should be provided with a one-line electrical riser diagram of the PV system components.
These drawings should accurately represent the installed elements of the system and should be provided to the homeowner (likely to be used by future solar installer for obtaining a building permit). To meet the requirements of the DOE Zero Energy Ready Home program, provide an architectural drawing and riser diagram of RERH solar PV system components and solar hot water.ĭevelop architectural drawings and diagrams that summarize the installed system equipment (conduit, etc.) as detailed below (see Figure 1). Department of Energy’s DOE Zero Energy Ready Home Program, require homes to be renewable-energy ready. Some energy-efficiency programs, like the U.S. A renewable energy-ready home (RERH) is one that is built with the wiring and plumbing conduit and other components in place to facilitate the future installation of solar photovoltaic (PV) panels and/or solar water heating panels.
