Payback period of a rooftop PV system can simply be defined as the time taken by which the initial investment made for the system will be recovered from the savings it makes.
To illustrate this, assume you invest $10000 in a project that gives you a profit of $1000 every year.
In 10 years, the profits together have paid back your original investment, and hence the payback period is 10 years. [...]
