Three things drive most of the state-to-state difference: your electricity rate (solar is worth more where grid power is expensive), your net metering policy (whether exported power is credited near retail rate or a lower "avoided cost" rate), and your local sun hours. Two identical systems in different states can have a payback period that differs by a factor of two or more. Pick your state above for a specific snapshot, or use the country/state selector inside any calculator directly.
