The Ayémé Solar Power Station is a proposed 120 megawatts plant in Gabon. The power station is under development by Solen, an (IPP). The solar farm will be developed in two phases of 60 megawatts each. The energy generated at this power station is expected to be sold to the Energy and Water Company of Gabon (Société d’Energie et d’Eau du Gabon) (SEEG), for distribution in , the capital city of the county and its surro.

In order to evaluate the financial feasibility of integrating energy storage systems with solar PV system in detached houses, economic indicators able to compare the costs of the different storage scenarios with one another are needed.
While the costs of all energy storage systems remain too high to be considered financially attractive without further support mechanisms, LIB storage is clearly the best storage alternative in all scenarios with a LCC 1000–7500 € higher and a LCOE 0.005–0.04 €/kWh higher than the costs of a 13.5 kW stand-alone solar PV system.
Hence, the optimal capacity of all the energy storage systems is zero, whereas the feasible solar PV size is limited to below 20 % when using the 2019 electricity prices as comparison.
For the battery storage system, a 90 % round-trip efficiency was used, representing the use of a generic LIB , . For the H 2 energy storage system, a 30 % round-trip efficiency was used, a value that could also be lower for small-scale energy storage applications.
Solar PV systems without selling surplus electricity to the grid were profitable up to a renewable fraction of 10 % with 2019 market prices and up to 35 % with the 2021 unusually high market prices.
While LIB storage clearly remains the most feasible energy storage technology with a LCOS of 3–5 times higher than the LCOE of grid electricity, the LCOS of the discharged energy from the H 2 storage and TES system is between 5 and 20 times higher than that of grid electricity.

The presented hybrid system is proposed for providing energy to utility customers in Iraq and for its energy sector. Iraqi consumers are experiencing a constant shortage of electricity, and the proposed solution for joint generation of energy by wind–solar installations will help solve this problem.
An experimental study was carried out using low power installations. The research results show that when using hybrid wind–solar systems to provide the energy complex in Iraq, the total production of the hybrid installation increases significantly.
The use of solar energy in Iraq depends on many factors, such as: the intensity of solar radiation; characteristics of solar energy; and the geographical location and climate of Iraq. An analysis of the climatic features of the city of Al Najaf in southern Iraq was carried out.
The cities of Iraq obviously have high rates of solar insolation. Solar energy is available almost everywhere for free and has a high output power for use in solar energy stations (SESs) and for the operation of photovoltaic converters. Thermal energy can also be used to heat air and water for domestic use [ 20 ].
A wind–solar hybrid energy system includes a rechargeable battery that is used to store energy from both sources. This energy is used when the wind flow is sufficient to start and maintain the operation of the wind power plant, and in the daytime, when the photovoltaic batteries convert the solar radiation flux into electrical energy.
This article presents the results of a study of a combined wind–photovoltaic installation for use in the energy sector of the Republic of Iraq. The presented hybrid system is proposed for providing energy to utility customers in Iraq and for its energy sector.
