Question #5 Error?
« on: March 22, 2012, 03:43:30 PM »
From my perspective, this problem should have used "Latitude -15" in its calculation. If we go with the understanding that an "at latitude" tilt results in a 41.53 degree array tilt, then in this example, with the roof being at 26 degrees (which just happens to be 15 degrees less than latitude) we should use a solar irradiation of 4.8 hours based on the "latitude -15". Figure 14 on page 17 bears this out. Any dissenting view points?

Disregard my previous comment. I must have read their answer incorrectly, because they did use the -15 tilt angle to arrive at the answer, oops.
