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...

“…This is known as the "solar constant". The total solar radiation intercepted by earth's surface can be calculated by multiplying solar constant with cross-sectional area of the earth [26]. In order to calculate the solar radiation received, on average per square meter of earth's surface, we divide the above multiplied result by the surface area of the earth.…”

“…So we are charmed to know that the measure of this vitality truly accomplishes the Earth's surface. Nature absorbs around 68 W/m 2 and reflects 77 W/m 2 .The radiation achieving the world's surface is 198 W/m 2 .The force of sunoriented radiation additionally relies upon the time and the topographical positions [26]. From Figure 3, we can see that each square meter of the upper areas of air gets 342 Â 67 W/m 2 of vitality consumed by the climate and 77 W/m 2 is reflected as shown in Figure 3.…”

The consumption of petroleum product assets on an overall premise has required an earnest look for elective vitality sources to get together the present-day request. The world likewise faces the double difficulties of petroleum derivative exhaustion and CO 2 discharges plus the fundamental competitor for confronting these difficulties. However, safe and economic concepts for CCS have not been proven, nuclear suffer from high cost, radioactive waste management, fuel availability, and nuclear weapon proliferation issues, and renewable, other than hydropower, have been limited by resource limits, high cost, and intermittency problems. In any case, the later intense cost decreases in the creation of photovoltaics (PV) which makes ready for empowering sun-based innovations to end up cost focused on petroleum energy generation. The target of present work is to evaluate the capability of sun oriented solar power at Chandigarh University, which lastly built up a framework depending on the potential estimations for a picked region of 1050.1416 m 2. At the end, cost estimation of SPV is determined to indicate whether it is monetarily practical or not.

“…The inclusion of secondary energy sources (such as storage systems) improves the reliability of PV systems but also increases their cost. The high initial cost of PV systems is one of the main factors that hinder their use [3]. Therefore, PV systems should be optimized to achieve high reliability at the least possible expenses.…”

A standalone photovoltaic system mainly consists of photovoltaic panels and battery bank. The use of such systems is restricted mainly due to their high initial costs. This problem is alleviated by optimal sizing as it results in reliable and cost-effective systems. However, optimal sizing is a complex task. Artificial intelligence (AI) has been shown to be effective in PV system sizing. This paper presents an AI-based standalone PV system sizing method. Differential evolution multi-objective optimization is used to find the optimal balance between system’s reliability and cost. Two objective functions are minimized, the loss of load probability and the life cycle cost. A numerical algorithm is used as a benchmark for the proposed method’s speed and accuracy. Results indicate that the AI algorithm can be successfully used in standalone PV systems sizing. The proposed method was roughly 27 times faster than the numerical method. Due to AI algorithm’s random nature, the proposed method resulted in the exact optimal solution in 6 out of 12 runs. Near-optimal solutions were found in the other six runs. Nevertheless, the nearly optimal solutions did not introduce major departure from optimal system performance, indicating that the results of the proposed method are practically optimal at worst.
