<p class=MsoNormal>The common metric for many consumers when considering a PV
system purchase is the $/watt cost of the installed system. This misleading
metric allows low-priced bottom feeders (those licensed and unlicensed contractors
working out of their garage or storage spaces) to clobber those of us who pay
all of the taxes and insurances and infrastructure costs to run a
brick-and-mortar operation with employees, etc.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>But when it comes down it, what really matters to the
consumer is not the $/watt installed cost but the kWhs produced by the system
over time. For what good is a cheap PV system if its output is poor?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Our focus as PV integrators should instead be to emphasize
the superior performance of our offered products, as in kWhs produced. <o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>To that end, where can we go for objective performance data
comparing brands X, Y and Z in monitored side-by-side testing over time?
Ideally if we had multiple sites worldwide, with multiple climate conditions,
we would be able to see whether a 2 kW array of brand X put out more power than
brand Y.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Can anyone point me to readily available data comparing the
performance of the major mod manufacturers in side-by-side testing?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Gracias amigas y amigos,<o:p></o:p></p>
