Abstract: A solar resource measurement system captures an orientation-referenced image within a field of view of a tilted surface that includes a skyline, detects the skyline within the orientation-referenced image to establish a set of zenith angles as a function of azimuth angles associated with the skyline, and determines a solar resource for the tilted surface from the orientation-referenced image and the set of zenith angles as the function of azimuth angles that are associated with the skyline.
Abstract: A Solar Access Measurement Device (“SAMD”) located at a predetermined position is disclosed. The SAMD may include a skyline detector enabled to detect a skyline of a horizon relative to the SAMD, an orientation determination unit enabled to determine the orientation of the skyline detector, and a processor in signal communication with the skyline detector and orientation determination unit.
