<div dir="ltr">Hi Dana,<br>
<div><br>
</div>
<div>If I understand your situation correctly, this can get complicated and depends on how the usage pattern is. A user that consumes during the day will need a smaller system than one that consumes when the sun isn't shining. Usually it's not one or the
other but a blend of course.. </div>
<div><br>
</div>
<div>I think it means that anytime you are spinning the meter backwards, you get about 4/9 credit that can be applied to your bill. Your usage will be lowered 1:1 when the sun is shining, but at the time of export, it will only get a 4/9 return (the utility
can't tell what is non-usage and what is production). </div>
<div><br>
</div>
<div>You can set up the bounds of the system size by saying, </div>
<div><br>
</div>
<div>What would the system size be if all usage occurs when the system is producing (the old net metering approach)? 1 usage:1 production</div>
<div>What would the system size be if all usage is at night? In this case, you would need a system that produced 9/4 of the kWh to fully offset or a multiplier of 2.25.</div>
<div><br>
</div>
<div>To make it more complex, you would need to find out if credits carry forward month to month or if its trued up each month.</div>
<div><br>
</div>
<div>Utilities can make it hard to get data to size the system correctly, but I'd probably shoot for 130-150% for an average house where people work. </div>
<div>Its not very easy to sell solar now and give assurances at all.</div>
