Calculating Return on Investment (ROI)
Calculating the ROI of a solar energy system involves comparing the total cost of the system against the cumulative savings over its lifespan. This calculation considers factors like the initial installation cost, any applicable incentives or rebates, the average annual electricity savings, and the system’s expected lifespan. A simplified calculation can be performed as follows:
Total Savings = (Annual Electricity Savings x System Lifespan) + Resale Value Increase – Initial System Cost
ROI = (Total Savings / Initial System Cost) x 100%
For example, consider a system costing $20,000 with an annual electricity savings of $2,000, a lifespan of 25 years, and a $5,000 increase in resale value. The total savings would be ($2,000 x 25) + $5,000 – $20,000 = $35,000. The ROI would then be ($35,000 / $20,000) x 100% = 175%. This indicates a substantial return on the initial investment. Note that this is a simplified calculation and doesn’t account for potential maintenance costs or changes in electricity prices. More sophisticated ROI calculators, often available online from solar companies, incorporate these variables for a more accurate projection.
