Libya’s energy consumption has been increasing at a relatively fast rate due to population growth and economic development. Buildings are responsible for a considerable share of energy consumption where they are typically responsible for consuming over than 36 % of the total primary energy in the country, among which about 17% is accounted for meeting lighting load, and are playing an increased role in the energy demands of emerging economies in the next few decades.

The rooftop building integrated photovoltaic system is especially attractive for the deployment of photovoltaic (PV) systems which generate electricity through the direct conversion of sunlight into usable electrical power. In Libya, the rooftop PV systems offer an attractive platform for the future to achieve long‐term energy independence, while reducing environmental impact and sustaining a strong economy and society for future generations.

Renewable Energy Authority of Libya (REAOL) is a Libyan authority which is responsible for implementing, installing and erecting all types of Renewable energy sources. REAOL is launching a comprehensive project to use rooftop PV systems for individual buildings. The project aims to set up a total number of roof top PV systems on public buildings with different capacities ranged from 3 kWp to 10 kWp each, depending on the space availability, such that the total capacity of the whole project to be installed is about 3 MWp. The benefits offered by rooftop grid-connected photovoltaic power plant for the economical and sustainable deployment of renewable solar energy also include: Generate electrical power from renewable energy source, raise the awareness for the potentials of renewable energy of decision makers, officials and the people of Libya, create new workplaces, help local companies to make business, and accumulate experiences and expert knowledge with PV systems at different locations and under different environmental conditions throughout the country.  

In this paper, to understand and improve the operational behavior of rooftop PV system, a comprehensive study including the plant design and detailed performance analysis under a local climate conditions is performed.

In conclusions, the intention is that the results from this work will help in demonstrating the potential of the rooftop building integrated photovoltaic system in Libya. On the other hand, the benefits and challenges associated with facilitate increasing the penetration levels of PV systems in the electric network in Libya.
