摘要：
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 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.
