What does the Declination settings?

[tRoOlos]

Hi,

Question 1: Is the " Declination". setting, the tilt angel of the solar panels (roof pitch)?
So for example a declination of 25 means that the solar-panels are laying with an angel of 25 degrees on the roof?

Question 2: determining the declination:
if my solar panels are mounted parallel to my roof pitch is it best to determine my roof pitch and use that as declination?
For example, via a simple calculation like: https://www.dakkapellenprof.nl/dakhelling-berekenen/ ?

Best regards and thanks.

Q1: yes. 0° means flat to the ground and 90° standing like a fence

Q2. Up to you. I did the same and my results vary where i measure it. It is acurate enough
