In the literature, many studies outline the advantages of agrivoltaic (APV) systems from different viewpoints: optimized land use, productivity gain in both the energy and water sector, economic benefits, etc. A holistic analysis of an APV system is needed to understand its full advantages. For this purpose, a case study farm size of 0.15 ha has been chosen as a reference farm at a village in Niger, West Africa. Altogether four farming cases are considered. They are traditional rain-fed, irrigated with diesel-powered pumps, irrigated with solar pumps, and the APV system. The APV system is further analyzed under two scenarios: benefits to investors and combined benefits to investors and farmers. An economic feasibility analysis model is developed. Different economic indicators are used to present the results: gross margin, farm profit, benefit-cost ratio, and net present value (NPV). All the economic indicators obtained for the solar-powered irrigation system were positive, whereas all those for the diesel-powered system were negative. Additionally, the diesel system will emit annually about 4005 kg CO2 to irrigate the chosen reference farm. The land equivalent ratio (LER) was obtained at 1.33 and 1.13 for two cases of shading-induced yield loss excluded and included, respectively.

The study investigated the distinct environmental impacts and economic viability of domestic biogas technology in the countryside of Bangladesh. The study was carried out by a survey through personal interviews with biogas users. Seventy households were selected purposively and interviews were conducted through semi-structured questionnaires. The study mainly highlighted the potential reduction of greenhouse gas (GHG) emission and economic benefits of biogas utilization which were evaluated considering the substitution of traditional biomass fuels, by saving Liquefied Petroleum Gas (LPG) and cost of chemical fertilizer, and carbon trading. The economic benefits are addressed using some well-known economic indicators like Net Present Value (NPV), Payback Period (PBP), and Benefit-Cost Ratio (BCR). The results of the study revealed that a small-scale household anaerobic cow dung biogas digester not only exhibited the potential to cut carbon emissions on average by about 7.8 tons of CO2 equivalents yearly, but it also demonstrated the economic feasibility of doing so as the value of NPV and BCR was positive. This study recommends that the government approach, awareness program, and continuous and proper performing of the biogas technology are needed to intensify the multiples environmental benefits of the technology.

Households sector in Serbia presents a great chance for energy savings and introduction of RES in the future. The public policies in Serbia are currently limited, but this kind of study can influence public measures that would undeniably generate long-term social and economic benefits to the country. The aim of the present work is to assess economic feasibility of closed loop heat pump systems for heating and cooling purposes in Serbia?s residential sector. The heat pump system was compared to the most commonly used heating fuels in households. Results indicate that the implementation of ground closed loop heat pump systems for heating and cooling purposes in Serbia?s residential sector as a substitute for electric heating is economically feasible. Inadequate prices of natural gas and electricity in public supply are the main problems associated with the project?s financial benefits. The best results were obtained in the scenario with combined debt ratio (40%) and grants (~30%) for the project realization, for which equity pay-back period is approximately three years, while benefit to cost ratio is 2.52. Investigated financial metrics (equity pay-back, internal rate of return assets and net present value) indicate the same positive results considering financial viability of the project.

Few studies have been implemented to evaluate whether the renewable energy generation could fit into industrial locations in Saudi Arabia. We completed this feasibility study to investigate whether using photovoltaic (PV) solar arrays to power industrial cities at Saudi Arabia is economically feasible. The case study is a factory in Zulfi city, Riyadh Region. We used National Renewable Energy Laboratory's modeling tool, system advisor model (SAM) to evaluate the economic benefits of using a 150 kW DC PV system to cover 100% of the factory monthly power demand. Over 25 years, the system is estimated to generate about 6,000,000 kWh of electricity whose net savings are $398,000 (1 US$ is equal to about 3.75 Saudi Riyals) represented by a discounted cash flow. The proposed system will save the factory around $304,000 that would have to be paid in electric bills and will eliminate considerable amount of CO2 emissions. Sensitivity analysis has been conducted to determine the effects of underlying parameters on the economic feasibility of the proposed system. Levelized cost of electricity (LCOE) generated and net present value (NPV) are used as indicators of proposed system feasibility. The results indicate that these projects can be profitable under some certain assumptions and can potentially be generalized for all industrial locations in Saudi Arabia.

This paper aimed at assessing the economic and financial viability of solar-powered irrigation of tomato crop in Jordan Valley. Data were collected from 16 tomato farms that use solar-powered irrigation system. Another 16 farms with diesel-powered irrigation system was investigated for comparative reasons. Descriptive statistics, Cost Function Analysis (CFA), Life-cycle Cost Analysis (LCCA), Water Productivity (WP) and the financial indicators of Net Present Value (NPV), Internal Rate of Return (IRR), Payback Period (PP) and Benefit to Cost Ratio (B/C) were the main economic and financial analytical tools used in this study. The results of the study revealed that costs of inputs, labor costs and equipment and maintenance costs have had a lower adverse impact on the total revenues level when using solar-powered irrigation system. The results also indicated the preference of the investigated financial indicators (NPV, IRR, PP and B/C ratio) when solar-powered irrigation is used compared to diesel-powered irrigation. The results also revealed a lower cost of life of the farm under the use of solar-powered irrigation. The governmental policies and programs should be directed toward the concepts of renewable energy in general and solar energy uses in agriculture in particular. Special agricultural extension plans in training and capacity building of farmers and extension workers on the use of solar energy in irrigation of agricultural crops should be developed. Cooperation in the fields of solar energy between the Ministry of Agriculture and related parties such as the Royal Scientific Society and the Ministry of Energy should be initiated to conduct specialized researches in the fields of solar energy use in agriculture.

Abstract This paper presents the techno-economic feasibility analysis of an on-grid Photovoltaic Solar System (PVSS) subject to Mediterranean climate aging effects. The PVSS under study is considered installed on the roof of Shymkent airport, located in southern Kazakhstan. A PVSS performance degradation rate of 1.48%-per-annun was considered according to the Mediterranean climate prevailing in the location. A 25-year life-cycle cost analysis comparing the rated vs de-rated on-grid PVSS led to a positive Net Present Value (NPV), a less than 9-year equity payback, and favorable internal rate of return (IRR) and Benefit to Cost Ratio (BCR) in both conditions. The analysis demonstrates that despite the expected performance degradation associated to climatic aging, a convenient feed-in tariff (FIT) and attractive financial conditions, such as those present in Kazakhstan, conform a robust setting to promote on-grid PVSS in the country.

The thermal energy storage (TES) technology is an effective method to enhance the planning and the economy of the combined heat and power (CHP) plants, while it has still not been broadly promoted in China. In this paper we firstly establish a mathematical model for a Chinese CHP plant with TES. Then the EnergyPRO software is used to find the optimum type of the TES tank in a three-tariff electricity pricing market and the operation strategy of the CHP plant with the selected TES tank is studied. Thirdly, the economic benefits of the system with/without TES is evaluated. The results show that adding a TES tank with volume of 24000m3 can significantly increase operational profits of the CHP system and reduce the use of peak-shaving heat source.
