The 2019 Building Energy Efficiency Standards (Energy Code) includes prescriptive requirements to install solar photovoltaic (PV) systems as a part of newly constructed low-rise residential buildings. As part of the PV requirement, builders must verify and document the shading conditions of the installed PV system as specified in Joint Appendix JA11.4.
