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. A

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 C

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 h

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 design
