<p class=MsoNormal><font size=2 color=navy face=Arial><span style='font-size:
10.0pt;font-family:Arial;color:navy'>We have installed a number of these racks
both with and without micros. It’s a good system that allows for a lot
of flexibility in layout and design, and seems pretty durable once bolted
together. Just make sure to request the integrated bonding clamps (they also
have a leash, which adds considerable time to the job). The Enphase approved
bracket works well, but wire management with micros can be difficult. I
originally selected this rack because the top down clamps worked with the
flangeless SolarWorld 2.0 frame, but you really need that flange to keep your
wires up. If you do go Enphase I would recommend checking out the Heyco
SunRunner 2 cable clip (MPN S6404).<o:p></o:p></span></font></p>

sharp. They had an epdm cover, but I’m told they are not going to
include this in the future. I would recommend either a slip sheet under the
trays or you use the AET ballast pad to protect the roof membrane.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 color="#1f497d" face="Times New Roman"><span
style='font-size:12.0pt;color:#1F497D'>We’re preparing a design for a 2<sup>nd</sup>
story flat commercial office building roof using AET 15° stainless frames with
ballast. The 1920s vintage building is on the National Register of Historical
Places so fortunately the array will be hidden behind a 3 ft parapet. No
real problem there but a large amount of hvac equipment is squeezed into the
center of the roof to keep it invisible from the street per those same
historical mandates. This allows us a pretty large area on 3 sides of the
perimeter for the array. The array is about 25 kW but it is confined to a large
“C” shaped area just inside the parapet. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=3 color="#1f497d" face="Times New Roman"><span
style='font-size:12.0pt;color:#1F497D'>So having never installed this AET
product I’m looking for recommendations from Wrenches who have worked
with this before.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=3 color="#1f497d" face="Times New Roman"><span
style='font-size:12.0pt;color:#1F497D'>AETs design, made from my scale
dimensioned drawing tries to fill every open space but I plan to delete a few
modules and have basically one continuous array around 3 sides. There
will be a couple of access routes to the roofs edge to keep city safety officials
happy. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=3 color="#1f497d" face="Times New Roman"><span
style='font-size:12.0pt;color:#1F497D'>Also the limited space in the electrical
room will almost for sure require us to use either micro inverters or several
5-7 kW string inverters on the roof, not my favorite strategy. Some potential
shading by the south wall parapet may incline me to use both micros and string
inverters. <o:p></o:p></span></font></p>
