<div dir="ltr">That's good news! I'd like to keep Zep in the arsenal, especially for people that insist on a low profile look. One other thing that concerns me a bit is the long-term availability and replacements down the road. We've had this discussion in another thread about replacing 12V nominal modules. That's an electrical compatibility issue, but Zep may create another compatibility issue that can't easily be resolved. In the case of Zep with microinverters, if a module fails or breaks in the distant future and there is no replacement available, you can just say "oh well" and let it be. That's my argument for only using Zep with micros, not string inverters. Then again, that's a compelling argument for using micros in general.<div>

Solar will be providing updated span tables and compliance letters
based on ASCE-10 in the next few weeks. Regarding removal of modules
for service - it is common practice to remove up roof modules in order
to gain access to a module requiring service, regardless of the mounting
system. Zep’s recommended practices for module removal are detailed
within our installation manuals. Please note that Zep Solar does not
promote walking across arrays in order to remove a module for servicing,
as this may result in damage to the cells. Regarding microinverter
installations - Zep Solar continues to design innovative products for
the installation of module device electronics that will simplify the
integration and mounting of these devices in Zep arrays<br><br><br><div><div class="im"><div><p><span style="color:rgb(0,102,0)">For a brighter energy future,<br><br><br>Andrew Truitt <br>NABCEP Certified PV Installer</span><span style="font-size:10pt;font-family:Arial,sans-serif;color:rgb(0,102,0)">™</span><span style="color:rgb(0,102,0)"> (ID# 032407-66)</span></p>

If your AHJ requires ASCE 7-10, that is no longer the case. Florida Building Code 2010 requires use of ASCE 7-10, and ultimate design wind speeds have changed dramatically, so it's important to consider the method, not just the wind speed.<br>
<br>We liked Zep, except when you have to remove a module for service. Microinverter installations are a little clunky with Zep, even with module frames specifically designed for Enphase. Unfortunately, we stopped using the product for a variety of reasons, not the least of which were new code requirements in Florida.<br>
