<p class=MsoNormal>Hello, Team~<o:p></o:p></p>
<div>

<div>
<p class=MsoNormal>I'm laying out some Sanyo modules on paper. Twelve of them
fit the roof with almost too much perfection: this would be difficult to
install as it would fill the roof "edge to edge" in both directions.
Are there consistent guidelines about the amount of roof edge which must remain
uncluttered or is this mainly driven by the amount of aggravation that the
installer is willing to tolerate? Which organizations would want to influence
such decisions in the Atlanta region? Details are: residential, new
construction, wooden truss type roof framing, finish roofing yet to be decided.<o:p></o:p></p>

<div>
<p class=MsoNormal>I've seen fancy photos of rooftops which are covered edge to
edge, but I suppose those are "building integrated" PV systems
instead of discrete modules mounted above the roofing material. Who decides if
those are "OK' for no walkways compared to a roof that is fully loaded
with Sanyo type modules? How are such decisions made?<o:p></o:p></p>

</div>
<div>
<p class=MsoNormal>I like the "top clamp" style mounts but UniRac
SolarMount rail systems need about a 1" gap from one module to the next.
Is there anyone with similar hardware that can get a grip within a smaller gap?<o:p></o:p></p>
