Solar PV Arrays Face Challenges
My wife and I walk about three miles each morning, far enough for us to pass at least a dozen houses in our neighborhood with solar installations. I sometimes comment: “That guy’s roof doesn’t have the right exposure,” or “During winter, those trees in the south part of his yard are going to cast shadows on the array.”
Yes, shadows are a real pain in the neck, and need to be considered before the final decision is made.
As shown above, ground-mount installations face an additional challenge in this arena, one that could be called the “dog effect,” or its scientific equivalent, the “canis effectus.”
