“…With regard to the cost and availability of components, local manufacturing should be supported for components mined locally bearing in mind the global technology trend and local environmental regulations to optimize PV operations (Hoffmann et al 2019;Vikstrom 2020). For location spread and area coverage, off-grid technologies with scales of households to community should be encouraged and prioritized, with incentives such as feedin taxes and tax credits, especially as PV project lead time is the shortest for any power generation technology (Hancevic et al 2017;Jones and Olsson 2017;Ohunakin et al 2018;Khodayar et al 2019). In the scarcity of land for the PV projects, the use of rooftops should be encouraged and prioritized instead of agricultural land (Jones and Olsson 2017;Enongene et al 2019).…”

“…Then, the national energy policy, the Electric Power Sector Reform act of 2005, births the framework for private sector participation in electricity generation, transmission and distribution (Enongene et al 2019). The policy established a national energy generation target of 31% from all renewable energy sources by 2030 with solar PV delivering 76.36% of that for the States and Local Government Areas' (NREAP 2016;Enongene et al 2019;Khodayar et al 2019). The intention is for Nigeria to produce 30,000 MW of electric power by 2030 with 30% sourced from renewable energy termed "Electricity Vision 30:30:30" (NREAP 2016).…”

Background There is no gainsaying about the importance of energy to the growth, development and socioeconomic well-being of any society. Photovoltaics (PV) have been identified not only as a means of meeting the energy needs of the Nigerian population but also as a tool in its national development. In this study, we reviewed the policy efforts of Nigeria in improving the renewable energy spread and the PV operations and utilization across the country. Results The technical audit of PV operations in Nigeria is evaluated using questionnaires administered in the 27 Local Government Areas in Imo State, as a case study. The component items in the latent variable scales of the audit have been tested for internal consistency using the Cronbach’s alpha. The good variable scale “Appropriateness for energy need” indicated a dissenting perception, whereas the acceptable variable scales “Adequacy in energy efficiency” and “Sustainability of PV project” indicated significant confidence in their perceptions. The perception in the energy need, which is associated with the limitations in PV utilization, is perceived as wrongdoings. Conclusions The whistleblowing policy is advocated as a germane measure to reduce or stop these wrongdoings and improve PV utilization and spread in Nigeria.

“…Firstly, randomly generate a charging start time of the EV that obeys the probability distribution character illustrated in (4). Secondly, randomly generate a daily mileage of the EV, which follows the probability distribution character illustrated in (3), and then calculate initial charging SOC of the EV according to (2). Thirdly, randomly generate a random number ς that obey a uniform distribution between [0, 1].…”

“…At present, photovoltaic (PV) power stations are mainly integrated into the distribution systems as a form of distributed PV station (DPVS). It is obvious that large scale integrations of the DPVSs have dramatic impacts on the distribution systems [1], [2]. Meanwhile, EVs are mainly recharged from the distribution systems at the EV charging stations (EVCSs).…”

“…In its development to date, the utilization of solar PV panel technology still encounters various obstacles, such as those caused by operational environmental conditions and external factors that affect the performance and efficiency of the generating system [4]. Several things that can be considered for future developments are solar cell materials, modeling, integration with hybrid systems, implementation complexity, maximum power point tracking, and energy conversion systems [4][5][6][7]. In this case, testing Solar PV panels is important to pay attention to because of the many influencing factors.…”

Indoor testing with a solar simulator is recommended to acquire the steady-state performance of a PV Solar Panel. Because of the simplicity, reproducibility, and dependability of data, the solar simulator allows for more efficient test findings. This can be accomplished by modifying and manipulating the test circumstances as needed. Several conditions must be met during the testing of the solar simulator, including power density, uniformity and stability of irradiance intensity (not exceeding 10%), spectral energy distribution, and angle of sunlight incident. Besides, the light source that replaces the sunlight is an important factor in developing a solar simulator. In this study, halogen lamps were chosen because of their reliability, low cost, and easy availability in the market. This solar simulator is designed for experimental testing on the development of Solar PV panels with a capacity of 50 WP. The solar simulator test performed at a distance of 75cm between the lamp and the solar panel, with five voltage variations: 100 volts, 125 volts, 160 volts, 190 volts, and 225 volts. Based on the ASTM E927 standard, the results of the solar simulator test in class B are obtained with an effective area of 16%. This result brought the best non uniformity of 2.61% at a voltage of 190 volts and the highest irradiance intensity of 1156.313 W/m2 at 225 volts.
