Solar Panel Payback Calculator

Find how long a solar system takes to pay for itself.

Payback period (years) 8.333

25-year net savings ($) 30,000

Formula: payback = system cost ÷ annual savings

Step-by-step with your numbers:

1. Values used:

2. System cost = 15,000 $

3. Annual savings = 1,800 $

5. Payback period = System cost / Annual savings = 15,000 / 1,800 = 8.333years

6. 25-year net savings = 30,000$

Estimate when solar panels pay back their cost in energy savings.

The math behind it

payback = net system cost ÷ annual savings. Panels typically last ~25 years.

$15,000 ÷ $1,800/yr → 8.3 years.
