[RE-wrenches] Pathfinder vs. Suneye

[Dana Brandt]

Hi Wrenches,

We've been using the Pathfinder along with the Pathfinder Assistant
software for several years and mostly like it. My concern with it is
there's no way to combine two or three shading images to account for a
string of modules spanning those different shading conditions. I've spoken
with the Pathfinder folks and they don't seem to understand or acknowledge
that limitation. How have you dealt with this?

So I bought a Suneye. Their software can apparently calculate string
shading including multiple solar access readings.

I took both the Pathfinder and the Suneye out on my next site assessment
and have run the results of side by side measurements. The Suneye is
showing about 10-15% better solar access for each measurement that the
Pathfinder Assistant software. I'm concerned to see such different numbers.
Has anyone else done a side by side comparison? What have you seen?

Thanks,

Dana
