Solar photovoltaic (PV) system is one of the matured solar-to-electricity conversion technologies with a great potential for residential applications. For wider adoption of PV systems, there is a need for an accurate sizing and economic assessment tool to inform decision makers. In this study, we propose a new optimization model based on integer programming for the adoption of stand-alone PV systems in the residential sector. The proposed model not only determines the optimal number of PV modules and batteries but also assesses the economic feasibility of the system through annualized cost. The model takes into account site-specific data in finding the optimal sizes. The effectiveness of the proposed model is assessed through a case study in Bursari, Nigeria. The result obtained from the model reveals that establishing a solar PV system is not only environmentally friendly but also about 30% cheaper than the diesel generators that are currently in use at Bursari. In particular, annually about 361 USD per residential building could be saved if the proposed system is used to replace the diesel generators. Finally, this study also, provides valuable managerial insights about the effect of several parameters on the performance of the proposed PV system.

Economic feasibility of solar PV system for rural electrification in Sub-Sahara Africa
Okoye, Chiemeka Onyeka; Oranekwu-Okoye, Blessing Chioma (2018-02-01)
The future of solar photovoltaic (PV) systems as a viable alternative to conventional fossil fuel-based resources seem promising with the rapid decline in the cost over the last decade. Notwithstanding, PV technology is yet to make a meaningful contribution in Sub-Sahara Africa (SSA) where the need for energy is deemed critical. The reason being that the technology is perceived by policymakers in SSA not to be capable of functioning profitably as an independent economic unit that requires project financing....
Optimizing the orientation of solar photovoltaic systems considering the effects of irradiation and cell temperature models with dust accumulation
Al-Ghussain, Loiy; Taylan, Onur; Abujubbeh, Mohammad; Hassan, Muhammed A. (2023-01-01)
To cope with the growing installation capacities of solar photovoltaic (PV) systems in desert areas, it is necessary to revisit the energy production models and the optimal angles of PV panels given the significant impacts of ambient temperature, wind speed, dust accumulation, and cleaning frequency. In this study, these four factors are examined for four PV technologies (polycrystalline, microcrystalline, monocrystalline, and thin-film) at three cities in Jordan, Egypt, and Tunisia using precise ground-lev...
Technical potential of rooftop solar photovoltaic for Ankara
Kutlu, Elif Ceren; Durusoy, Beyza; Ozden, Talat; Akınoğlu, Bülent Gültekin (2022-02-01)
Turkey, which has immense solar potential, has recently shifted towards solar energy and new renewable energy deployment regulations, including implementation and commercializing rooftop PV technologies. Thus, these require a detailed assessment to determine the power source's capability and convince the policymakers. To the authors' best knowledge, there is no available data or a city-based study for the rooftop PV potential in Turkey. Here, we present the first city-based rooftop PV potential study in Ank...
Study Case of Solar Thermal and Photovoltaic Heat Pump System for Different Cities in Turkey
Moia-Pol, Andreu; Pujol-Nadal, Ramon; Martinez-Moll, Victor; Bonyadi, Nima; Baker, Derek (2016-10-14)
The combination of solar thermal, photovoltaic, and heat pump technologies is a welcome advancement in countries with large solar resources such as Turkey. These systems could have similar efficiencies throughout the year for different locations in Turkey if we adjust the solar storage according to the weather conditions. In this paper, solar heating with a heat pump system for buildings have been designed to achieve different values of the fraction of primary energy saved using Flat Plate Collectors (FPC) ...
Operational Optimization of an Agricultural Microgrid
Brown, Paul D.; Göl, Murat (2022-01-01)
A demonstration agricultural microgrid containing solar photovoltaic (PV), battery storage system (BSS) and multiple water pumps and reservoirs is presented. A mathematical model of the cost of operating the demonstration microgrid is developed. The mathematical model includes hybrid inverter source switching and BSS charging modes in addition to power balance and inter-period energy and water-level coupling. Electricity pricing and irrigation water use efficiency are allowed to vary by time of day. The mat...
