Right. Besides that, batteries have a shelf
life. A few years down the line, the client will
need to replace the bank. A $10K reinvestment
after a few years could erase any cost
effectiveness of an off grid system. In many
cases they could pay the extra money and hook up to the power line now.

My design philosophy these days matches yours 100%, Allen. Because of cheap
PV, and FLA batteries still stuck in the 1910s. It was a different story
(not too many years ago!) when a good deal on PV was $5 a watt...

Hi Allen,
I use the 2-3 day autonomy design approach as well unless there are unusual
circumstances. Here in western Colorado this design approach has worked
very well. I have been met with some resistance with folks that are used
to the large 4-5 battery string designs that were common around
Dana (and I'm curious if others agree),
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
