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.

The Cost

Currently, the pork industry is incorporating in-line automation with the aim of increasing the slaughtered pork carcass throughput while monitoring quality and safety. In Korea, 21 parameters (such as back-fat thickness and carcass weight) are used for quality grading of pork carcasses. Recently, the VCS2000 system—an automatic meat yield grading machine system—was introduced to enhance grading efficiency and therefore increase pork carcass production. The VCS2000 system is able to predict pork carcass yield based on image analysis. This study also conducted an economic analysis of the system using a cost—benefit analysis. The subsection items of the cost-benefit analysis considered were net present value (NPV), internal rate of return (IRR), and benefit/cost ratio (BC ratio), and each method was verified through sensitivity analysis. For our analysis, the benefits were grouped into three categories: the benefits of reducing labor costs, the benefits of improving meat yield production, and the benefits of reducing pig feed consumption through optimization. The cost-benefit analysis of the system resulted in an NPV of approximately 615.6 million Korean won, an IRR of 13.52%, and a B/C ratio of 1.65.

In the field of agriculture, use of proper method of irrigation is important because the  main reason is the lack of rains and scarcity of land reservoir water. The continuous extraction of water from earth is reducing the water level due to which lot of land is coming slowly in the zones of  un-irrigated land. Another very important reason of this is due to unplanned use of water due to which a significant amount of water goes waste. The system derives power from solar energy through photovoltaic cells. Hence, dependency on erratic commercial power is not required. In this paper we use solar energy which is used to operate the irrigation pump. The circuit comprises of sensor parts built using op-amp IC. Op-amp’s are configured here as a comparator. Two stiff  probes are inserted in the soil to sense whether the soil is wet  or dry. A microcontroller is used to control the whole system by monitoring the sensors and when sensors sense dry condition of soil, then microcontroller will send command to relay driver IC the contacts of which are used to switch on the motor and it will switch off the motor when the soil is in wet condition. The microcontroller does the above job as it receives the signal from the sensors through the output of the comparator, and these signals operate which is stored in ROM of the microcontroller. The condition of the pump i.e., ON/OFF is displayed on a 16X2 LCD which is interfaced to the microcontroller. Further it can be enhanced in future by interfacing it with a GSM modem to gain control over the switching operation of the motor.

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 economic feasibility of solar wall system was assessed with RETScreen software for 15 widespread locations in northern China heating region. Several different economic and financial indicators were calculated, such as the internal rate of return, net present value, simple payback and benefit-cost ratio. Results showed that the solar wall system was only profitable for four sites according to the current domestic price of solar wall plate and its absorptivity. When the price was reduced or the absorptivity under the condition of invariable price was improved, there were more sites profitable for this system. So, only when the price of energy increases 95% or the price of solar wall plate falls 50%, the solar wall system will be profitable for all sites in northern China heating region.

A study was conducted from February to May 2020 to analyze the cost-benefit economics analysis and resource use efficiency of carrot production in Chitwan, Nepal. Altogether 70 households producing carrot were selected randomly and surveyed through the pre-tested semi-structured interview-based schedule. Data was entered and coded using SPSS 25 and analyzed using STATA 12.1. The study revealed that the total variable cost per hectare for carrot production was US $1803.1 and a benefit-cost ratio of 1.81 was estimated. Cobb-Douglas production function models the relationship between production output and production inputs . Production function analysis including seven explanatory variables, showed a significant positive effect of seed cost, tractor cost and human labor cost (P<0.01), fertilizer and manure cost (P<0.05) on gross return but herbicide cost, packaging cost, vitamin and micronutrients cost were found insignificant. The return to scale was found to be 1.42. According to estimated allocative efficiency indices, it is suggested to increase the seed, fertilizer and manure, tractor labor and  human labor costs by approximately 45%, 74%, 67%, and 79% respectively and reduce the herbicide and packaging costs approximately by 116% and 246% respectively. The adoption of modern technologies with adjustments to resource use should be suggested to maximize the productivity and profit from carrot production.

The Cost

The efficient management of water and energy is one challenge for managers of water pressurized systems. In a scheme with high pressure on the environment, solar power appears as an opportunity for nonrenewable energy expenditure reduction and emissions elimination. In Spain, new legislation that eliminates old taxes associated with solar energy production, a drop in the cost of solar photovoltaic modules, and higher values of irradiance has converted solar powered water systems into one of the trendiest topics in the water industry. One alternative to store energy (compulsory in standalone photovoltaic systems) when managing pressurized urban water networks is the use of head tanks (tanks accumulate water during the day and release it at night). This work intends to compare the pressurized network running as a standalone system and a hybrid solution that incorporates solar energy supply and electricity grids. The indicator used for finding the best choice is the net present value for the solar power water system lifespan. This study analyzed the possibility of transferring the energy surplus obtained at midday to the electricity grid, a circumstance introduced in the Spanish legislation since April 2019. We developed a real case study in a small town in the Alicante Province, whose findings provide planning policymakers with very useful information in this case and similar case studies

At present the economic development in the province of Bali between South and North Bali is very significant. This condition is presumed to be the transportation infrastructure for the connecting road of South Bali - the existing aiIDRort is not optimal. The alternative transportation infrastructure studied is the plan to build a railway line across South-North Bali. Mengwitani-Singaraja link road is required to be capable to provide more optimal accessibility so that there is an even distribution of economic growth.he indicators used in the feasibility analysis of economic aspects are net present value (NPV), benefit cost ratio (BCR) and economic internal rate of ruturn (EIRR) The price component is used by the shadowprice method. Costs calculated according to the life cycle cost of the project development. Benefits calculated include direct benefits in the form of passenger ticket income and indirect costs in the form of cost savings for existing road users, a multiplier effect, an increase in tourist visits to northern Bali. Economic analysis indicates that the planned North-North Bali railway line is worth proceeding, this is shown by the NPV indicator of IDR 860 billion, BCR of 1.11 and EIRR of 13.11% greater than the 12% price reduction rate. Although it shows that there is feasibility of economic studies, a strategy is needed to produce financial feasibility so that it can be offered in cooperation between government and business entities (PPP) in order to accelerate its developmen

Abstract This study proposes a sustainable solar-powered irrigation system (SPIS) for a 75-hectares rice farm in Krandegan Village, Purworejo Regency, Indonesia. The existing water pumping system uses diesel engines which cost around Rp. 200 million per year that cannot be provided by the farmers. The SPIS was designed based on water requirements calculated according to the Food and Agriculture Organization (FAO). The technical design of SPIS used Lorentz Compass considering local solar energy sources and the availability of SPIS components in the local markets. The entire farm in Krandegan requires 11 SPISs with a total capacity of the solar panel of 20.8 kWp. Also, the SPISs use 11 centrifugal DC pumps; 10 surface and 1 submersible type. The SPIS in Krandegan would require a total cost of Rp. 1.29 billion. Without the financial support of the capital costs from other parties, the simple payback time (SPT) would be around 6.5 years, which is good for a solar photovoltaic (PV) project. SPIS is not only a viable solution to replace diesel engines in supplying water to the rice farm in Krandegan, but is also in line with the seventh target of Indonesia’s Village sustainable development goals (SDGs).

Grain Drying

The main objective of this study was to simulate the economic feasibility of low-temperature grain drying systems considering Brazilian conditions and using three drying capacities, seven grain types and two furnace fuels. For this, 42 scenarios were simulated and compared among themselves by using an economic analysis based on the cash flow model with project lifetime of 20 years. The indices net present value, payback period, benefit-cost ratio and internal rate of return were applied during the analyses. Simulations showed that drying of coffee and beans in large systems presented higher economic feasibility, regardless of the furnace fuel used. All simulated scenarios were cost-effective provided that at least two drying cycles are performed per year. Labor costs, social taxes, grain type and drying capacity most affected the profitability of this kind of investment, while the furnace fuel less influenced the evaluated economic indices.
