The demand for electric power has been increasing due to the increase in population and the development of the cities. Therefore, there is a need to avoid processes that use large amounts o...

The present work proposes the engagement of relatively cold air exhausted from Heating, Ventilating and Air Conditioning (HVAC) systems, that exist in structures such as residential commercial and industrial, to reduce the PV modules’ operational temperature. To proceed, a thermal resistance model in steady state is developed along with its corresponding iterative procedure and calculations which are carried out for different configurations and scenarios. The thermal modeling was validated by comparing it to experimental measurement found in the literature. It was revealed that the PV modules’ temperature can be reduced with increasing the mass flow rate of the exhaust air. However, the air mass flow rate depends on the cooling load need; which increases with increasing the cooling load. The efficiency of the PV has shown an increase from 11 to 18% when the cooling load increases from 0 to 160 kW for a solar radiation of 500 W/m2. Moreover, there is an optimum height for the exhaust air duct for each cooling load that must be determined.

The current status of the Lebanese electricity system necessitates an urgent solution. Lebanon’s power shortage, manifested in the daily power outages (load shedding), and whose main cause is the insufficient power generation capacity, has become an unbearable event in Lebanon. In view of that, renewable energy technologies emerge as the suitable solution, since Lebanon proves to have a notable renewable energy potential including an important average wind speed, active water resources, high daily solar irradiance, and outstanding geothermal resources. In this paper, a new innovative solution has been proposed to improve the power generation capacity of an existing Lebanese thermal power plant (Deir Ammar). Which is located in northern Lebanon, it is to be supported with an offshore wind farm. This proposal has good potential to be feasible since it utilizes the unused area next to the power plant, exploits the high average wind speed, and provides a notable boost in MW rating of the existing thermal power plant.
