<div dir="ltr"><div>Hi Jay,</div><div><br></div><div>Per your note, annual kWh production should go up as you add more modules to a project, even if you are increasing the DC/AC ratio.

<br>
I’m working with a customer who’s pretty savvy and is using PV watts for his design. <br>
<br>
What I can’t figure out is the kwh/year goes down if he uses dc/ac ration of 1.5 instead of 1.2 which is the default.<br>
<br>
Hes in Santa Fe NM.<br>
<br>
.8 ratio= 1663 kwh/yr<br>
1.0 ratio = 1668 kwh/yr<br>
1.2 ratio = 1671 kwh/yr<br>
1.5 ratio = 1623 kwh/yr<br>
<br>
I was expecting that more PV = more kWh/yr.<br>
<br>
What am i missing?<br>
<br>
<br>
standard module<br>
fixed roof mount<br>
14.08 loss’s<br>
10 degree tilt<br>
180 degrees <br>
