A draft of these requirements
was released on July 31, 2014, with the most current
draft version showing a date of August 27, 2014. There are many areas of interest to
appraisers in here, including a distinction on how owned and leased PV systems are to be
evaluated, the impacts of shading on a PV system, and a discussion on the different
approaches that can be used to measure and report contributions to value.
