Solar payback factors homeowners should compare
Solar payback comparisons work best when cost, generation, usage, export assumptions, and battery choices are shown together.

A useful payback view starts with the installed cost, then adds expected generation, household usage, export assumptions, and maintenance expectations.
Battery storage can improve self-consumption for some homes, but it also changes the starting cost. That is why RIO treats payback as a comparison question rather than a single fixed number.
