Well, it also depends on specifics of the install: how close the wires are to each other, if their shadows line up along the axis of the modules, etc. At the very least it's likely to be a good candidate for a microinverter install, to minimize shading effects.<br>

don't mention the distance but probably not, even if they are close. The further
away the lines, the faster the shadow will move out of the way. Further, the
time of the year would have to be a player and, if you are bit uncomfortable
about this, it might be quite easy to ensure the shadows are only an issue in
summer.</font></span><br></div>

Shading of Photovoltaic Collectors<br><br></font></div>
<div><font face="Arial" size="2">I am evaluating a site to install
photovoltaics. I am aware that there is a big penalty for partial
shading. The potential location that is without obstructions almost all
the time between 9am - 3pm all year, except for 5 power lines. The poles
do not shadow the potential collectors. Is that enough to significantly
reduce performance. Otherwise, the location is excellent for the
other more solid obstructions like trees and buildings. </font></div>
