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... Dan Fink Adjunct Professor of Solar Energy Technology, Ecotech Institute IREC

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
