A local coffee shop has installed a small solar energy system to reduce overhead costs. The initial investment covered solar panel installation and equipment, totaling $20,000 after solar incentives. The business reported energy savings of approximately $2,500 annually, achieving a calculated ROI of 20% and a payback period of just over three years. The transition also enhanced customer appeal by promoting a green image.


  • Costs: $20,000 (initial investment)

  • Annual Energy Savings: $2,500


Solar Cost Benefit Analysis Calculations:

Payback Period = Initial Investment / Annual Savings 

20,000 / 2,500 = 8-year solar payback period


Total Savings Over 20 Years

Total Savings = 2,500 X 20

*assumes electricity rates stay constant for 20 years


Return on Investment

ROI = (Total Savings − Initial Investment) / Initial Investment X 100

ROI = ((50,000 - 20,000) / 20,000) X 100 = 150%


Summary:

  • Payback Period: 8 years

  • Total Savings over 20 years: $50,000

  • ROI: 150%



#2: Medium-Sized Company Solar Installation

A manufacturing firm installed a solar energy system to lower operational costs. The initial investment, covering solar panels and necessary equipment, totaled $100,000 after solar energy incentives.
