Solar Loan Calculator
What a solar loan costs over its term, and what it returns against avoided electricity.
Result
Simple payback, with no discounting and no financing cost. For anything large or long, money now is worth more than money later and a lender will want interest, both of which make the real return lower than this.

About this calculator
Why is there no interest rate?
Because it is a first-pass check. If the payback is short the financing cost rarely changes the decision; if it is long, model the loan properly before committing.
What payback period is acceptable?
Shorter than the life of the thing, with room to spare. Equipment that pays back in four years and lasts five is a bet on nothing going wrong.
The formula
payback = cost / (monthly gain - monthly running cost)
