<div class="moz-cite-prefix">Th one factor I don't think any of us
have enough info on yet is the reduced lifespan of the inverter.
Heat kills electronics, and an inverter that is running at max
capacity more of the time will be running hotter. The MTBF (mean
time between failures) is only going to get worse at higher heat,
so then question becomes how much worse? With lease programs and
financing that uses up to 30 year projected lifespans, I think
we're going to see some long term issues come back to bite those
that saved a few cents/ watt up front.<br>

<div class="gmail_extra">As someone who designs very large
systems, I agree with Isaac. There's no one r; ,ule for
inverter sizing as there are a multitude of factors in play.
Solarpro's article "Levelized Cost of Energy" in the
April/May 2012 issue goes into inverter ratios and how it ties
into LCOE.</div>
