I've got a photo essay about one incident that I prepared on just this
topic. It shows photos of the shadow from a triplex cable that is
about 5 feet from a PV crossing several modules. The shadow only lasts
for about 40 minutes very early in the morning, but it reduces the
output by 20% during that time (the shadow also covers about 20% of a
row of cells). Production data from Enphase's Enlighten web site shows
how the shaded module output compares to a nearby unshaded module.<br>
<br>
If you (you meaning any RE-Wrench) want a copy send me a note off
list. The file is approximately 5 MB so it takes a while to upload or
download. <br>

<p>Hey there,</p>
<p>We have a string inverter system installation coming up that has a
power line suspended over the roof. The line is diagonal to the roof
and about 20' above the surface. It will be very challenging to
configure the strings to mitigate shading. Does anyone have experience
with the effects on producion from the thin shadow cast by the
powerline? </p>
<p>Thanks</p>
