A method of determining one or more shading conditions associated with a structure is provided. A method may include determining an azimuth of a reference roof edge relative to an orientation of a first image of a structure. The method may further include determining a relative azimuth of the reference roof edge from a lower hemisphere of a second, different image captured proximate the structure. In addition, the method may include determining one or more shading conditions associated with the structure based on the azimuth of the reference roof edge and the relative azimuth of the reference roof edge.

Solar photovoltaic measurement, and related methods and computer-readable media

A method of determining one or more shading conditions associated with a structure is provided. A method may include determining an azimuth of a reference roof edge relative to an orientation of an aerial image of a structure. The method may include capturing at least one spherical image at at least one measurement location proximate the structure. Further, the method may include determining a relative azimuth of the reference roof edge from a lower hemisphere of the at least one image. In addition, the method may include determining an orientation of an upper hemisphere of the at least one image based on the azimuth of the reference roof edge and the relative azimuth of the reference roof edge. Furthermore, the method may include calculating shading conditions based on the orientation of the upper hemisphere of the at least one spherical image.

Solar photovoltaic measurement

A solar power measurement method is provided. A method may include determining an azimuth of a reference roof edge relative to an orientation of an aerial image of a structure. The method may include capturing at least one spherical image at at least one determined measurement location proximate the structure. Further, the method may include determining a relative azimuth of the reference roof edge from a downward view of a lower hemisphere of the at least one image. In addition, the method may include determining an orientation of an upper hemisphere of the at least one image based on the azimuth of the reference roof edge, the relative azimuth of the reference roof edge, and a known tilt of a roof edge of the structure. Furthermore, the method may include calculating shading conditions for a time period for known sun positions during the time period based on the orientation of the upper hemisphere of the at least one spherical image.
