Fig. 5 Yearly Energy Generated ECOS model further determines the LCOE to be about $3.81. As discussed earlier LCOE is a function of the Life cycle costs (LCC) and the energy generated. The ECOS model is among the first tools to accommodate the external costs of energy generation which in this case are the environmental costs and the health costs. The cash inflow and cash outflow for the whole period is shown in Fig 6 and Fig 7. The cash flow is highest at the beginning of the project and minimum near the end of the lifespan.
Fig. 6 ECOS Model Cash Inflow 6.2. HOMER Results HOMER simulation estimated the total NPC to $1.7 billion while the optimal LCOE was $1.07. HOMER found the optimal LCOE by considering 138 combinations in which only 66 cases were feasible. The resultant of the input output cash-flow is as shown in Fig 8 below. In the cash-flow the plant breaks-even on the final year of production where the cash-flow is positive.

Globally, attention has majorly been focused on pollution and exhaustion of fossil fuels allied to the conventional energy sources while the non-conventional energy/renewable energy sources have always been considered clean and environmentally friendly. Of the two, the non-conventional (renewable) is being preferred because it is believed to be more environmentally friendly. Renewable Energy Technologies (RETs) especially Solar Photovoltaics have seen many plants being constructed to either supplement the grid or as alternatives for those far from the grid. Solar Photovoltaics plants occupy large tracts of land which would have been used for other economic activities for revenue generation such as agriculture, forestry or tourism in archaeological sites. The negative impacts slow down the application of Solar PV , but a modelling tool that can easily and quantitively assess the impacts in monetary form would accelerate the Solar PV application. The work presents a developed modelling tool that is able to assess not only the techno-economic impacts but also the environmental impacts in monetary form, for one to be able to determine the viability of a plant in a given region. The results are compared with those of HOMER software.

... HOMER, SAM, HOGA, and RET Screen are some of the most well-known Techno-Economic instruments [4]. HOMER is widely acknowledged as the global standard for HRES optimization and one of the most extensively used optimization and sensitivity analysis tools [5,6]. Homer software was created by the United States New Energy Laboratory (NREL) [7], which provides costeffective improvements for small renewable energy power generation facilities integrated with conventional energy producing systems. ...

Analysis of the Levelized Cost of Electricity (LCOE) of Solar PV Systems Considering their Environmental Impacts on Biodiversity

... As the study presents scenarios up to 2050, three values of LCOE were used: 0.25 [17,69], 0.12 [16,70], and 0.069 [14]. These are meant to represent the gradual decrease in price for solar PV electricity generation throughout the study timeframe and are assumed to represent the LCOE for 2030, 2040, and 2050, respectively. ...

... The job landscape pans out in the form of established and opportunistic importers, technicians, and solar sales agents. Kenya, which is perhaps only second to South Africa in terms of technology, skills, and competence, is able to develop Solar PV systems and expand her on-grid industry (Kibaara, Murage, Musau, & Saulo, 2020). Recent statistics project that annual job growth rates within the industry will be at a percentage point of 26 points by the year 2024 11 . ...
