A typical 6 kW system in Saudi Arabia
At around SAR 6 per watt, a 6 kW rooftop system costs roughly SAR 36,000 and produces about 10,591 kWh in its first year at Saudi Arabia's 6.2 peak sun hours a day. Your real numbers depend on your roof, shading, panel choice and how much power you use during the day — run your own figures in the calculator to see your exact payback, net savings and ROI.
How the solar calculator works
