Calculating the ROI of Commercial Solar System

Calculating your return on investment for a solar project is fairly straightforward, and this ROI calculation applies to all projects stretching up to thirty years. 

To establish an accurate picture of the overall financial benefits you'll gain from implementing commercial solar energy solutions, consider factors such as:

  • Your current utility kilowatt-hour (kWh) rate and any demand charges.
  • Your annual bill without solar.
  • The projected annual increase of utility costs over 25 to 30 years based on historical increases.
  • The projected amount of solar kWh your system will produce over 25 to 30 years
  • The lifetime costs associated with the solar installation, including installation costs, inverter replacement, operations and maintenance cost
  • The estimated value of all solar rebates, performance based incentives, and tax incentives received over 25 to 30 years.
  • Any applicable taxes.
  • Any applicable interest/loan costs.

To calculate the ROI of a solar system we'll need to:

  • Find the total benefit received over its lifetime
  • Divide that by the total cost of the installation
  • The multiply all of that by 100%
