Techno-economic viability of off-grid standalone PV-powered LED street lighting system in Lagos, Nigeria

A Capabilities-Led Approach to Assessing Technological Solutions for a Rural Community

“…In order to do this, we needed to discuss basic capabilities, and our reference point for this was Nussbaum's list of 'central capabilities' [21] (pp. [33][34]. This is a list of 10 broad, non-overlapping capabilities, theoretically derived, which are intended to cover the irreducible, non-overlapping basic dimensions of a life of dignity that would allow an individual to flourish.…”

“…Off-grid lighting systems, using solar PV and LEDs with integrated battery storage, have been assessed in a number of studies [29][30][31][32][33][34], but these focus on cases of streets for motorized traffic, where luminance levels are higher than for pedestrian use. Reported costs are highly variable, which may be due to how many opex/capex factors have been considered, the timing of getting costs, and the pricing of goods in different markets.…”

Identification and Analysis of Impact Factors on the Economic Feasibility of Photovoltaic Energy Investments

“…Table 3 shows a summary of the impact factors identified, the classification in which they were included, the references, and the total number of times they were found in the articles. 190,191,193,196,[199][200][201][202]214,216] -175,177,179,180,183,185,186,188-193,195,196,198-200, 202,204,206,207 Operation and maintenance time [17,19,37,44,51,52,56,64,69,70,76,77,90,98,104,106,116,118,127,130,131,136,145,148,154,165,166,173,175,186,193,195,196 Azimuth and angle of incidence are the angles formed between the projection of the sun's rays and the earth's surface, and vary according to the movement of the sun. These angles should serve as a reference in the assembly and installation of the PV panels, to maximiz...…”

“…Bimenyimana et al [17] consider replacement costs, in addition to investment and maintenance costs, during the life of the installation. Babatunde et al [19] studied investment in solar energy for public lighting and additional costs related to the battery of the PV module, the charging controller, and costs of LED lamps were forecast in order to save on the energy expenditure of the PV system. Haegermark et al [115] say that the costs of the PV system include, in addition to the investment cost and operation and maintenance costs, inverter replacement costs and additional costs associated with the generation of PV electricity.…”
