Good luck, feel free to PM me via the forum if you have any questions about what I did. One of your questions might help me figure out why my numbers depart so weirdly from the NREL hourly numbers. BTW, I get the same “butterfly wing” like pattern when I compare hourly results against the SolarR simulator so I think whatever is causing the difference is systemic. Similar butterfly wing pattern in this thread.
And as I suggested earlier, if I aggregate by month I get something that is very linear between my monthly Sense data vs. the NREL results. You have convinced me to break out my other 6 years of solar history for comparison against the NREL PVWatt yearly template.
Slightly improved and commented script below.
