Theoretical Solar

It's only taken me to now (since changing my set up) to notice that the theoretical solar value is substantially lower than the value coming from my sensor.

The sensor is nice & clean and we have lovely clear blue skies:

I know changes we made in CMX a few versions back, but I left those settings alone, as they were always spot-on for me. Should I change the RS Transmission factor? 0.83 has been my value for quite some time, and if it needs adjusting, it would require some jump to get close to what my actual readings are.

Looks like it needs a tweak to the December value, today is a good day to do it here as well, very clear. I do it a small step at time.

Thanks Mark! :)

First day in a long time that it hasn't been cloudy or overcast! I'm starting to go transparent. :lol:

I've just updated to the latest version, so now need to tweak the solar values.

I used to use 0.83 which (I think) gave a good curve match for Match / Sept. Assume I need a higher value for Dec, and a lower value for June, and if I say add say 0.06 to make Dec 0.89 I take 0.06 away to make June's 0.77.

Can anyone in the UK share what they have tried / used.

Thanks.
