“…The unit cost of electricity was estimated to be 0.74 USD kWh/d. Oko et al [37] designed a stand-alone PV system for Port Harcourt in Nigeria and carried out economic analysis of the proposed system. The authors concluded that sorting the input data in an automated MS Excel (version, manufacturer, city, state abbreviation if USA and Canada, Country) spread sheet would help in performing design and economic analyses of PV systems in any geographical location.…”

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...

Economic Feasibility Analysis of Off-Grid Pv Systems for Remote Settlements in Bhutan

Through rigorous rural electrification projects, over 99.97% of Bhutan's households now have access to electricity, which is predominantly generated from run-of-the-river hydropower plants. Despite this achievement, around 5% of the rural households still do not have access to electricity to meet their cooking load demands and, therefore, they extensively rely on firewood, LPG, and kerosene for cooking purposes. Apart from hydropower, penetration of other renewable sources such as solar and wind power in the country is negligible. Thus, an attempt was made to determine the investment costs of installing PV systems for off-grid households in remote settlements by studying their economic feasibility. The study shows that the initial cost of investment for an off-grid Solar Home System for a rural household is US$1.42 per Wp using polycrystalline PV modules and US$1.55 per Wp using monocrystalline PV modules. The average cost of installing SHS is determined to be US$ 2342.67 per household. The results of analyses indicate that standalone SHS for remote rural households is not financially viable with the current price of electricity supply in Bhutan. However, SHS provides a more cost-effective option than a grid-line extension, which is estimated to cost about US$ 6700 per household for the remaining off-grid settlements.

“…Where is the daily energy required from the battery, DOD is the permissible depth of discharge, AD is autonomy days, is the ampere-hour efficiency of the battery cell, and is the selected nominal DC voltage of the battery block [2,10]. The values of the factors considered while calculating for battery size are battery loss 0.85, 4-days of autonomy, depths of discharge, DOD -0.8, and battery's nominal voltage.…”

In this paper, the design and simulation of an On-grid photovoltaic system for the faculty of Engineering, Abuja campus, University of Port Harcourt (Latitude: 4.78°S, Longitude: 7.01°E) was researched inorder to verify alternate power source possibility that can supplement for the inconsistent power from the (Power holding company of Nigeria) grid to the faculty. The system Solar modules are mounted in a fixed tilt orientation in 4-parallel strings of 15 Solar panels in series on the roof-top of the faculty. The photovoltaic system is also designed with a two-parallel string of nine Tesla Powerwall batteries in series for the battery bank storage system. Inverters used for this system are two 9.9kW battery-based grid-tied inverters stacked in parallel with an inbuilt Maximum power point tracker (MPPT). The reinjection system is on-grid as a net-meter is not used since the Power Holding Company of Nigeria, PHCN does not support Net-metering. Thus, power is not injected into the grid from the solar photovoltaic system. In solving the faculty's power lapses and improving power supply quality in the faculty, data collected both within the faculty. These methods include data collection, evaluation of load data, data analysis, suitable design adoption, simulation of data. A solar photovoltaic software application package called PVsyst was employed for various simulations and plots. The end simulation and final work prove the system to be 57% efficient in performance.
