What Is Solar ROI?
Solar Return on Investment (ROI) measures how quickly your solar system pays for itself through electricity bill savings and how much money it generates over its 25-year lifetime.
The Simple Solar ROI Formula
Payback Period (years) = Initial System Cost (AED) ÷ Annual Electricity Savings (AED)
