That's the answer I thought I'd get from most. It's hard to explain the "days of autonomy" and extended bad weather to people. Most just say, "why don't you just make a recommendation." That puts me in a spot where I want to overbuild, which drives up cost.
The other challenge is getting people to tell you the real story about what they plan to plug in. They think 100W @ 120V continuous load 24 hours a day sounds like a very small load. When you hit them with a ~1kW system with a ~10kWh battery (with ample reliability factors considered), they freak out. Then you find out that the camera they wanted to plug in only draws 18W @ 12V (no inverter required). That's a big difference.
