[Greenbuilding] Power Line Shading of Photovoltaic Collectors

[Keith Winston]

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.
