Dana (and I'm curious if others agree),<br>
I used to work with 4-5 days of storage, back with modules were
expensive and batteries were relatively cheap. As in recent years
these two have reversed - modules are cheap and batteries are dear -
my fundamental design approach has changed. I now design around 2-3
days of storage with a larger array, as long as there's a backup
generator in the system. I size to at least 100% of the projected
winter average daily load. <br>
<br>
The batteries recharge more quickly, including on partly cloudy days
between storms. They spend more of their time full, thus keeping
them happier and giving them as much or more life, even with more
and deeper cycling. FLAs are easier to EQ, given the hotter charge
rate. And the customer spends less.<br>
<br>
You used to live in SW Colorado, a similar sunny winter climate. Is
it the same in Idaho where you live now? <br>
