“…For the economic analysis, we meticulously computed both revenue and costs, employing a comprehensive evaluation of key investment parameters to assess the economic viability of the installation [8]. The Net Present Value (NPV), a pivotal metric in financial appraisal, was determined to gauge the difference between the present value of all cash inflows and outflows over a specified timeframe.…”

To achieve renewable energy mix target and support the Indonesian Government’s policy on the use of solar power, PT. PLN Indonesia Power Bali has installed Floating Solar Photovoltaic (PV) above the surface of the Muara Nusa Dua reservoir. The 100 kWp Floating Solar PV was showcased at the G20 meeting held in Bali. In this study, a techno-economic analysis was carried out for the 100 kWp Floating Solar PV. The data collected was the real time data from the production of the 100 kWp Floating Solar PV and the costs incurred for the investment. The results of this study showed an average energy yield of 145.93 MWh with expected revenue of Rp 236,406,729.60 annually. Furthermore, the NPV and IRR were calculated and the resulted values were Rp 2,810,168,240.00 and 5.73 %, respectively with payback period approximately of 13 years. This showed that the 100 kWp Floating Solar PV is feasible investment to increase renewable energy mix in Bali – Indonesia.

“…To solve this issue, many researchers have proposed similar methods of optimization in different countries, such as Chad [15] and Côte d'Ivoire [16]. The techno-economic assessment of a 100kW solar rooftop PV system for five hospitals in central and southern Thailand was studied in [17]. It is critical to provide an energy supply that can deliver uninterrupted electric power to meet the load demand as a hybrid system (WT and DG), as has been studied using WT models in different comparative models of wind characteristics between south-western and south-eastern Thailand [18].…”

This paper presents a new of economic and environmental study of a hybrid system (wind turbine and diesel generator) in Algerian desert regions using HOMER software. The principal interests of the hybrid system are clean production at the place of consumption, the combined use of resources, energy storage, and supply security. Using an experimental device outfitted with Homer software, models were developed and successfully compared to reality. The obtained results confirm that the proposed system proved to be accurate enough to distinguish energy transfers and fast enough to enable optimizing the sizing and handling of the system's energy transfers. The purpose of this paper is to confirm the robustness of the HOMER software and to check the technical, economic, and environmental criteria of the integrated system.

“…However, the deployment of solar energy should be accelerated because, by 2030, it is anticipated that its production, along with that of wind energy, would make up the majority of all electricity generated (IPCC, 2022). Utilising photovoltaic (PV) systems to capture solar energy is an effective method of producing clean electricity with limited operating costs and minor environmental effects (Khamharnphol et al, 2023).…”

The potential output of photovoltaic (PV) panels is influenced by several factors, including the direction of solar radiation from the sun toward the panel’s surface. The maximum output of the panels is obtained when the panels are vertical to the sun's rays. In this study, a techno-economic analysis is conducted to examine whether an automatic one-axis sun tracker system is an economically feasible option for installing a large-scale PV park in the Nicosia district in the central part of Cyprus. The performance of a one-axis sun tracker with an installed capacity of 781 kWp is compared to a PV system with a fixed flat structure having the same capacity and larger capacity at 1034 kWp. Output generated by the three PV system options is simulated by three alternative simulation software (SolarGIS, PVSyst, and PVGIS). Financial analysis is performed utilizing simulated PV power output, accounting for electricity feed-in tariff and overall cost of the project. The cash-flow model is run for several scenarios defined by different leverage ratios, including no leverage. Considering the technical parameters of a PV system and solar panel characteristics, such as the degradation effect on solar panel efficiency and solar radiation, we estimate the solar tracking system produces about 20%–30% more energy compared to a fixed structure. We find both technologies are economically viable options, however, a one-axis tracker system performs better financially. LCOE in all scenarios is below the highest acceptable level for solar PV projects in Cyprus which is 103 EUR per MWh. LCOE for a solar tracker PV is 39 EUR per MWh with a 30% leverage ratio and up to 79 EUR per MWh with 85% leverage. LCOE for a sun-tracker is ~20% lower than LCOE for a PV with a fixed axis of comparable size. Despite higher investment costs, the solar tracking PV system performs with a 12% higher equity internal rate of return, and a 9% shorter loan payback period compared to the same installed power of a fixed structure. The Financial analysis is complemented by quantified benefits due to avoided carbon emissions. Accounting for carbon benefits makes a sun-tracker PV system economically a better option over the fixed tracker PV system, resulting in 228,000 EUR more benefits. Overall, the present value of net benefits of a solar-tracker PV amounts to 1.39 mil. EUR and due to high irradiation in Cyprus, the carbon footprint of PV power output represents only 6% of the footprint of generating electricity in thermal power plants. When these benefits are accounted for the sum of NPV and social benefits will turn out to be higher for a one-axis tracker compared to the total social benefits of a fixed tracker of the same size.
