Jay,
I don't really remember, it was years ago that I had that setup, and did
not have any way to keep records except on paper which I did not do.

Hi BradOut of curiosity, what is the actual difference between the two on those cloudy days. ThxJayOn Oct 25, 2023, at 5:04 PM, Bradley Bassett via RE-wrenches wrote:I used to have both an array at a 60° tilt and one at 14° tilt. In the winter the high tilt array did better on sunny days, and on

And we have plenty of them this time of year!AmosSent from my Galaxy

Dave,
The paper reference was at the bottom of my original post (1), but a
quick summary of what they recommended was exactly what you mentioned -
Have two axis trackers "go horizontal" during heavy overcast instead of
continuing to track the sun to improve production!
I'm familiar with
Kirk,
Can you reference your paper on this? So many variables and each
location will be different. Most dual axis
trackers can always be left flat or any angle so that does not make
sense to me.
You have to design for winter offgrid if the location is worth it. Or,
alot of hours on a
I used to have both an array at a 60° tilt and one at 14° tilt. In the
winter the high tilt array did better on sunny days, and on cloudy days the
shallow array did better. They were different modules and different sized
arrays, so without more analysis than I did, it would be hard to tell which
Hi All!
We don't do a lot of pure off-grid systems and I recently ran across
something I wanted to run by folks with more experience in this area:
Optimal array tilt for our very cloudy PNW winters!
My understanding has always been that latitude plus 10-15 degrees was the
best tilt to address
