I didn't say it wasn't. We're talking about the cost per kWh which depends on the interest rate that you can finance it with, not your ROI.

- toomuchtodo 8y agoYou should always be paying cash whenever possible for the remaining system cost (after incentives). Failing that, you should be able to get a HELOC, home equity loan, or roll the system cost into a first mortgage at low (~4%) fixed rates (that might also be tax advantaged). Higher interest rates would change the equation, but I don't know of people who are using high interest loans (like an unsecured loan) to finance residential solar.
