What solar systems are you selling that have a 40 year output guarantee? That is pretty rare, most of what I am seeing is 20-25 years for 85% (or greater) output.
The $1200 in utility savings, if realized, still has a 10 year ROI, even after discounting for what a generator would likely cost (~$5K installed).
Both systems would add value to the house, proportionate to their acquisition prices.
If you have electric heat, or worry that you might need to rely on any form of electric heat during storms and outages, I think a 10Kw solar system would be VERY undersized, unless you are willing to heat only a small area to "survival" temps instead of "comfort" temps.
