<font size=2 face="sans-serif">Hi:</font>
<br>
<br><font size=2 face="sans-serif">One thing to keep in mind with clipping,
(module over sizing), is that if a system has 10%-15% off clipping, that
will not affect total annual energy harvest and depending on dust and temperature
conditions will likely even improve it.</font>
<br>
<br><font size=2 face="sans-serif">Heres' a graph which shows the energy
harvest graphically for a 250W module with a 250W inverter and a and 300W
module with a 250W inverter.</font>
<br>
<br><img src=cid:_1_0C7FCB680C7FA7D000635D8188257DE8><font size=2 face="sans-serif">
</font>
<br><font size=2 face="sans-serif">Please note the graph does not include
any dust effects. To compensate for dust, the modules should always
be of the order of 4% more powerful than the inverter, unless you plan
on washing modules every month.</font>
<br>
<br><font size=2 face="sans-serif">Related to this, large commercial systems
we have been supplying inverters to are 30-70% oversized as the sinking
cost of modules makes the return on investment come out as maximized in
that range of oversizing,</font>

<br><tt><font size=2>That would be at the 120% rating, so by rule
of <br>
thumb, OK. I have a ground mount that has a <br>
ration of 1.15% with M-190s (figuring 199 W / <br>
inverter). It has quite a bit of clipping in the <br>
spring. It has optimized tilt for the location. A <br>
ballasted roof mount with a 10 or 15 degree tilt <br>
likely wouldn't have that issue.<br>
<br>
This system went in the spring of 2010, and has <br>
only had one M-190 failure out of 24, amazingly enough.<br>
