Mixed/Use Building Rooftop PV Feasibility Study

We would like to study the prospect of installing photovoltaic (PV) panels on the rooftop of mixed use building in Abidjan, the capital of the Ivory Coast in West Africa. Specifically, we would like to have a study of the panel/battery/inverter number/layout/type/capacity...before we proceed with an installation. The building is South Facing and is located on Avenue Delafosse in Plateau, the business district of Abidjan. The building has 2 different entrances, each with its own elevator. Unless you have other ideas, we are looking to cover the needs of our offices (located in the building), common areas (lighting, elevators...) as well as Burger King, the tenant on our ground floor (Refrigeration, AC, lighting...).
