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. In particular, JA11.4(a) specifies that the verification must be done using a solar assessment tool that is approved by the executive director.

Approved Solar Assessment Tools

The following solar assessment tool has been approved by CEC for use as specified in JA11.4(a)

Note: For CF2R verification purposes the satellite, drone or other digital image of the obstructions that cast shadows on the PV array must be created and dated after the installation of the photovoltaic system.
