Switching to solar isn’t just about going green — it’s one of the smartest financial decisions you can make in Dubai. With high electricity tariffs from DEWA, excellent net metering, and world-class solar irradiance, most homeowners and businesses see their investment pay back in just 4–7 years.
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.
Payback Period (years) = Initial System Cost (AED) ÷ Annual Electricity Savings (AED)
