The study determined optimum roof tilt and building azimuth for rooftop-based distributed photovoltaic (PV) energy generation in Ikeja, Lagos State, Nigeria as strategic technological input to alternative power new housing development Metropolitan Lagos. planning & foresight analysis methodology was used. data were obtained via literature, Global Positioning System (GPS) systems, models site visits; comprised manual satellite imagery, dimensions, angles coordinates of the structures area (Rows between 0 – 60o, Columns 180o; sizes: 533 kW, 110 kW 0.547 kW). results showed solar array yield varied from 768,944 kWh per annum a 500 kVA system 780 VA system. A five tier rooftop template 245 MWp consequently developed. Optimal systems estimated be 5o 180o respectively though combinations not exceeding 30o 90o gave acceptable yields. concluded that policy intelligence inputs renewable programmes Federal State Governments.
