<p class=MsoNormal><span style='color:#1F497D'>Nowhere close. I’m
not a believer in using micro inverters for large commercial projects.
Plus, I’m pushed to the limit on this particular project to keep the
costs down in order to satisfy the PPA investors. Off-line I’ll
tell you what I’m charging. I never thought I could/would go that
low. But our industry (and I’ve been in the RE biz since the late
1970s) has been taken over by bean counters, financiers/bankers and
lawyers. (Sorry, Michael….)</span></p>

<p class=MsoNormal>What’s the feedback on these Tigo buggers?
I’m not talking about sites where shading is an issue, but a nice big
commercial roof with no shading.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Specifically, I’m talking about a 400-module system
feeding into a single PV Powered 100 kW inverter.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Anyone have an opinion whether spending another $15,000 on
gobs of little tiny Tigos would be worth it as far as increased kWhs
production?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Obviously it’s in Tigo’s interest to say
emphatically yes. But I is wonderin’.<o:p></o:p></p>
