size=2 face=Arial>I understand that the cost of electricity in Hawaii is pretty
high so cost can be justified. But don't forget the cost of bolting up each
optimizer. And the cost of doubling the number of cable connection, now and
possibly in the future. Complexity increase cost in the long
run?</FONT></SPAN></DIV>

already about 1/4 the cost of an Enphase. So how close are you to moving from an
optimizer / inverter combination to a microinverter?</FONT></SPAN></DIV>

<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>
