Jeffrey,
I agree. We do structural analysis on every roof design and factor in the point
loading at the attachment points. I had floated this idea because it came from
an SE that I work with that also has a PV system. His theory is the definition
snow loads are accumulation of snow over time.
Friends:
Thanks for the responses to my question. Here is what I have learned:
The main problem is that the Sunny Boy is remote from the house and there
is no signal conduit. There are any number of monitors that can hard wire
to the Sunny Boy, usually with an RS485 connection.

There is a company called Digi.com. they make a wireless bridge for the RS-485
protocol. Needs to be line of sight, but it will travel about 1000'.
They are familiar with installers using their radios to communicate with our
inverters, set up is pretty straight forward.
I am looking for a part

i have set up wireless bridges for ip to remote locations and my experience
with this has me leaning towards no dice william.

Hi William,
I have successfully used this product below on a few installs without line of
sight, trees, hills, etc in the way approx 1 km span doing exactly what you are
asking for - wireless RS485. It costs more than WiFi bridges, but it also
works!

William,
I would have to concur with Randy's chart pretty much. A couple
months a go we bought a 2012 Toyota RAV4 EV. I had just recently completed
an upgrade system here (4.5KW PV, Classic, 84 KW of Rolls batts and a
