I can certainly calculate the statistics, but I need some time first for more urgent
matters such as updating as well as replacing the modeled solar on all the 2017 weather
files. From what I've seen so far,? I expect the aggregate totals to change a little for
US locations because the modeled solar had already been calibrated against satellite solar
from another source in 2015, while for Canada and Europe the changes might be from a
little to moderate, and larger still for other parts of the world.? On an hourly and even
daily basis, I expect the differences to be much larger, but who's to say that the
satellite data which are on a 3-5km grid are necessarily better?? Please stay tuned.
