“…In the funding gaps, there should be financial support policies such as a third-party financing option for both residential and commercial projects (Alsabbagh 2019;dos Santos Carstens and da Cunha 2019). For the shortage of skilled professionals, the training and retraining of technicians and artisans being issued verifiable certifications are vital (Mukai et al 2011;Akinyele et al 2019; dos Santos Carstens and da Cunha 2019). In the PV technologies deployed, incorporating recent trends rather than obsolete technologies should be prioritized such as the use of recent conversion efficient generation of PV cells, the use of bifacial PV modules, incorporating Phase Change Materials in projects to enhance cell efficiency of PV modules and incorporating solar trackers in the PV installations (Smith et al 2014;Njoku 2016;Hussin et al 2017;Liang et al 2018;Akinyele et al 2019;dos Santos Carstens and da Cunha 2019).…”

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.

“…The different studies above, assuming that capital is unconstrained, indicate research hypotheses under capital constraints and uncertain backgrounds; the results reveal the relationship between government subsidies, green finance, and carbon reduction [37]. Subsidies support specific production behavior, as governments put forward per-unit subsidies, preventing the green supply chain from undergoing cost influence, while other financial institutions provide green credit to the green supply chain, which undergoes manufacturing or retailing capacity restrictions [38]. Government subsidies have already become a significant method for reducing carbon emissions.…”

We consider a coal supply chain with a coal enterprise and a manufacturer, where the coal enterprise invests in clean coal technology, and the manufacturer invests in carbon reduction technology. The government offers subsidies for the investments of clean coal technology and carbon reduction technology. We examine optimal clean coal technology inputs in a coal enterprise and carbon reduction quantity in a manufacturer under the modes of coal-enterprise-led and manufacturer-led, respectively, using a Stackelberg game theory model. We obtain some interesting results. First, carbon reduction by the manufacturer is restrained when clean coal technology cost and carbon reduction cost are increased, regardless of the dominant modes, and clean coal technology input decreases when clean coal technology cost increases; however, a high carbon reduction cost has no effect on clean coal technology input when the manufacturer leads. Second, the clean coal technology subsidy for coal enterprises promotes clean coal technology inputs and carbon reductions, and the carbon reduction subsidy encourages carbon reduction without supporting clean coal technology input. Last, carbon reduction performance is better achieved under the manufacturer-led model than the coal-enterprise-led model. However, it should be noticed that the capital resource only relies on government subsidy in this article. In the future, this study could be used for green supply chain investment, and could be helpful for sustainability development.

“…In this case, either the solar photovoltaic module or the solar concentrated technology is employed for harnessing the energy from the sun depending on the application involved. In other words, solar energy technology in distributed generation application is classified into the solar photovoltaic and solar thermal systems [55,56]. In a typical off-grid situation, battery storage is required because of the intermittent characteristics of the solar energy resource.…”

Energy demand has constantly been on the rise due to aggressive industrialization and civilization. This rise in energy demand results in the massive penetration of distributed generation (DG) in the distribution network (DN) which has been a holistic approach to enhance the capacity of distribution networks. However, this has led to a number of issues in the low voltage network, one of which is the voltage rise problem. This happens when generation exceeds demand thereby causing reverse power flow and consequently leading to overvoltage. A number of methods have been discussed in the literature to overcome this challenge ranging from network augmentation to active management of the distribution networks. This paper discusses the issue of voltage rise problem and its impact on distribution networks with high amounts of distributed energy resources (DERs). It presents different DG technologies such as those based on conventional and unconventional resources and other DERs such as battery storage systems and fuel cells. The study provides a comprehensive overview of approaches employed to curtail the issue of voltage increase at the point of common coupling (PCC), which includes strategies based on the network reinforcement methodology and the active distribution network management. A technoeconomic comparison is then introduced in the paper to ascertain the similarities and dissimilarities of different mitigation approaches based on the technology involved, ease of deployment, cost implication, and their pros and cons. The paper provides insights into directions for future research in mitigating the impact of voltage rise presented by grid-connected DGs without limiting their increased penetration in the existing power grid.
