Claim 9:
10. A method to determine solar exposure on a roof of a structure, comprising:
obtaining images of a portion of a roof of a structure;
identifying within the images an existing obstruction proximate the structure identified to cast a first shadow on the portion of the portion of the roof of the structure for a first amount of time during a current month;
identifying within the images a future obstruction proximate the structure that:
is not estimated to cast a shadow on the portion of the roof of the structure during the current month, and
is estimated to cast a second shadow on the portion of the roof of the structure for a second amount of time at a future date; and

calculating a total irradiance on the portion of the roof of the structure during a time period based, at least in part, on the first shadow of the existing obstruction and the estimated second shadow of the future obstruction.
