Solar Payback Period in Pakistan - What Affects ROI
Factors that shorten or lengthen payback: tariff escalation assumptions, system cost, financing cost, and maintenance.

Simple payback math
Divide net installed cost by annual bill savings to get a rough payback in years. If financing adds interest, include finance charges in the net cost.
Tariff increases can improve payback on paper, but they are not guaranteed-stress-test with flat tariffs too.
Hidden costs
Include inverter replacement reserves, cleaning, and any insurance. Exclude payback claims that ignore inverter end-of-life.
