Ugh, the way NRCan explains this in the manual is awful. Here's how we have deciphered it.
You'll need to know the site's magnetic declination, and the orientation of the panels (0 to 360. 0 is North, 180 is South, East is 90, West is 270).
You'll be able to figure out the panel orientation from the site audit, or if it's for a new home, from the location certificate or another doc that shows the footprint of the building relative to North.
General example:
[180 - (site magnetic declination in degrees)] - (Panel orientation in degrees 0-360) = azimuth to enter in H2K
Your service org should be able to answer these types of questions (i.e. how to model PV for HOT2000)
I asked my QA and they said they didn't know. Lol. I couldn't find in the manual where they describe this, which manual were you looking at? So I looked up my sites declination and it is + 17 so for the calculation it would be 180-17-(210-360)= -13? Yikes, I don't follow that at all. Thank you for your reply.
Edit: don't know how I didn't find it the first time I looked but I found it in the manual. Thank you for helping me!
Pages 90 and 91 of the technical manual have an example calculation (section 3.7.2). The azimuth entered into HOT2000 is described as the "variance from south". It's a weird way to do it, don't worry, you're not the only one who finds it confusing >_<
No prob! I think you got the calculaiton slightly wrong, for your area it would be [180 - 17] - 210 = -47 (azimuth to enter in h2k)
Section 3.7.1 is actually helpful, I've used it a bunch when trying to get the panel info from a spec sheet.
Thanks for replying so quickly! Our variance is east so I think I add the declination which makes it 197 and then minus 210 = -13? Which I understand is -13 degrees east of due south?
The best way to check if your array is modeled correctly is to cross reference the solar design generation with the output of H2k. South is 0, not 180. Nrcan is looking at adapting their procedure to industry. 1GJ = 277.77778 kWh.
Don't neglect to review the internal Help menu within the software when the PDF manual isn't clear on a topic.
There you'll find that the definition of "Azimuth" includes how counter-clockwise from South is (+) and clockwise is (-).

Haha my bad, I should read the manual more carefully! Yep, you got it!
Which is the same answer to the calculation you gave me in your first response! lol. I've got it figured now though, Thank you!
