“…15.095 kW/h. Hassan et al [50] proposed a stand-alone PV system to electrify an emergency health clinic in Egypt. The analysis including sizing, simulation, and economic assessment of the system showed that a 3.3 kW PV array and 20 batteries (6 V, 1156 Ah, 6.94 kWh) were needed to meet the total load of the clinic.…”

Access to clean and affordable energy in rural African regions can contribute greatly to social development. Hence, this article proposes the design, simulation, and optimization of a stand-alone photovoltaic system (SAPV) to provide non-polluting electrical energy based on a renewable source for a rural house located in Tazouta, Morocco. Real monthly electrical demands and hourly climatic conditions were utilized. An initial design process indicated that, with a 1080 W p total capacity of PV modules and 670 Ah of battery storage, the proposed SAPV system was able to meet a considerable part of the dwelling load with an average solar fraction of about 79.1%. The rest of the energy demand was ensured by a diesel generator (DG). Also, a life cycle analysis of the PV system revealed that the life cycle cost is 10,195.56 USD and the unit electricity cost is 0.57 USD/kWh for an initial investment of 4858.68 USD. Thereafter, an optimum design based on Homer Pro software was carried out indicating that lower PV capacity can decrease the unit energy cost to 0.356 USD/kWh while reducing the solar fraction to 54.9%.Energies 2019, 12, 4735 2 of 16 society [1]. Access to electricity has not only been identified as an essential element for socio-economic development, but also contributes towards poverty reduction in society [2]. However, electricity generation and its supply are not distributed equally in the world, especially in rural regions [3][4][5] that also suffer from the low quality of the power supply distribution services [6,7]. Yet, most of African countries, for instance, are still underdeveloped both in terms of infrastructure and power network, despite large, ongoing renewable energy projects in the region. In fact, there are about 620 million people in this continent that have no access to electricity, which is equivalent to two-thirds of Africa's population [8].Of the 315 million people in rural Africa who are expected to have access to electricity by 2040, only 30% of them will be connected to national networks. The others will be connected to off-grid or mini-grid power systems [9]. Kofi Annan, chairman of the Africa Progress Panel and former UN secretary general urged African governments and their partners to do their utmost to combat the enormous energy deficit in Africa. This joint appeal was launched on Monday, 13 March 2017, at the ADB headquarters in Abidjan, Ivory Coast on the occasion of the launch of the Africa Progress Panel report entitled "Light, Energy, Action: Electrifying Africa", which calls for adopting all existing solutions-network and off-grid systems-to illuminate Africa and power it [10].It is no great surprise as this continent has an abundant potential of solar, hydro, wind, and geothermal sources of energy and contains significant quantities of natural gas. Some countries even have coal deposits. The great challenge for Africa is to exploit and manage these resources and make them contribute to its economic development and ease for the inhabitants. Morocco, which belongs to the north...

“…Hybrid renewable power systems integrate two or more sources of energy, one of which is renewable, optionally a storage system and typically work in stand-alone mode [1], [2], [8]. To introduce renewable energy sources in hybrid power systems we also have to deal with the following disadvantages: renewable resources availability in different locations, intermittency, unpredictability, multiple economic and technical optimization criteria, unquantifiable environmental benefits, etc.…”

Hybrid renewable power systems integrate two or more sources of energy, one of which is renewable, optionally a storage system and typically work in stand-alone mode. They are being considered more and more and we should increment their usage taking advantage of their positive benefits: free of charge resource availability, CO2 emissions reductions and subsidies. Dealing with their inconveniences: variability of renewable resources availability and cost acquisition, through the optimization of the design and the control of the system. The optimal design of hybrid renewable power systems is usually defined by economic criteria. But there are also technical and environmental criteria to be taken into account to improve decision-making. In this paper a discussion on different criteria will introduce the non-economical perspectives in addition to the economic criteria. A case study of a PV-Wind-Diesel-Battery system for a Telecommunication station in Catalonia is discussed. Availability of renewable energy sources is obtained with RETScreen and PVSyst. Analysis and simulations of various hybrid power systems have been done in HOMER resulting on a comparison of different scenarios. Optimal scenario taking into account the best results of all three types of criteria: economic, technical and environmental, is a trade-off of the economic optimum.

“…In the literature, numerous researches discussed the techno-economic feasibility of hybrid renewable power systems [1][2][3][4][5][6] or PV power systems [7][8][9][10] using HOMER simulation tool. Techno-economic feasibility studies in the literature variated in their input data resources due to many climate databases available online.…”

The aim of this study is to evaluate the variation in techno-economic feasibility of PV power system under different data sources of solar radiation. HOMER simulation tool is used to predict the techno-economic feasibility parameters of PV power system in Baghdad city, Iraq located at (33.3128° N, 44.3615° E) as a case study. Four data sources of solar radiation, different annual capacity shortages percentage (0, 2.5, 5, and 7.5), and wide range of daily load profile (10-100 kWh/day) are implemented. The analyzed parameters of the techno-economic feasibility are COE ($/kWh), PV array power capacity (kW), PV electrical production (kWh/year), No. of batteries and battery lifetime (year). The main results of the study revealed the followings: (1) solar radiation from different data sources caused observed to significant variation in the values of the techno-economic feasibility parameters; therefore, careful attention must be paid to ensure the use of an accurate solar input data; (2) Average solar radiation from different data sources can be recommended as a reasonable input data; (3) it is observed that as the size and of PV power system increases, the effect of different data sources of solar radiation increases and causes significant variation in the values of the techno-economic feasibility parameters.
