Additionally I've heard that some people also keep a generator for certain emergency conditions. In particular this is a family living on the far west edge of Calgary.
The rate and periods of return though are quite important, as is the expected maintenance and replacement costs/timing. With solar technology and efficiency evolving so rapidly right now, a super sale priced item today may already be ridiculously obsolete by the time it's installed (because it may have been warehoused for 2+ years).
All that being said, our camping trailer has a ~5yr old solar system and we've gone camping for 10 days straight without any power shortages off the batteries.
