Using the Erratic Application of Solar Photovoltaic Panel Installations to Power Agricultural Submersible Pumps in Deep Wells in Order to Extend Productive Times and Boost Water Production

Due to the surge in oil prices, alternative energy sources, like solar power, are being explored to meet energy demands. Solar power is utilized in various industries, including agriculture. In Iraq and other developed countries, solar power is actively being developed due to the abundance of solar radiation. In agriculture, solar standalone pump systems with variable-speed drives are used. Electric motors operate at different speeds depending on the availability of sunlight. Inverters convert this solar energy from direct current to alternating current, enabling the powering of motors with a fixed voltage per frequency ratio and regulating motor current consumption. The variation in motor speed affects hydraulic pump efficiency and water productivity, making it crucial to optimize solar energy utilization in agriculture. The angle of inclination greatly affects the effectiveness of solar panels. The optimal tilt angle depends on location, latitude, season, and time of day. Adjusting this angle based on these factors maximizes power output. Innovative installation methods are being employed to enhance the benefits of solar power, reduce costs, and optimize sunlight capture. These methods drive sustainable development in various industries, including agriculture.

A computational ascertainment of Hall and ion slip implications over a stretched regime with chemical reaction and internal heat source

This study is inspired by the emerging importance of micropolar fluids in a variety of scientific and technical fields due to varied uses and effective thermal activities. Potential applications of these fluids include cancer treatment, magnetic refrigeration, drug delivery and magnetic resonance imaging. Hall and ion repercussions on unstable magneto micropolar liquid beyond a stretched sheet are described in this article. By using the bvp4c, the resulting non-sequential coupled PDEs are transfigured into a system of coupled non-consecutive ODEs, which are remedied by a numerical procedure. An impact of various governing non-dimensional factors on velocity, angular momentum, temperature, concentration, wall friction, couple stress, local Nusselt and Sherwood numbers, is indicated graphically. The main finding specifies that Hall and Ion impacts influence velocity and with increased Hall and Ion effects, velocity raised as well as thermal boundary layer reduced. When compared to previous findings in the literature, the current findings indicate a splendid agreement. The predominant uses of this issue are in solar cell systems, such as solar water pumps, manufacturing and production processes, motion in plasmas, furnace design, nuclear power plants, and solar aircraft wings.

Analysis of the Influence Factors of the Crude Oil Temperature Maintenance System of Solar Sewage Heat Pumps in Cold Regions

Traditional crude oil heating methods that use fossil fuels or electricity have the disadvantages of high consumption of nonrenewable resources, low energy utilization, and high carbon emissions. Therefore, it is urgent to develop green and sustainable crude oil heating technologies. In this paper, a solar synergistic sewage heat pump (SSHS) dual heat source crude oil temperature maintenance system is proposed. The system utilizes clean and sustainable solar energy to heat crude oil while combining sensible heat storage technology and the waste heat utilization technology of a sewage source heat pump to solve the unstable fluctuation of the solar heating problem. A simulation and analysis model is established to analyze the influencing factors of the SSHS, and the optimal operation scheme is provided. The results show that the efficiency of the solar collector decreases and the proportion of crude oil heating increases with an increase in the solar energy guarantee rate, while the unit flow rate of the pump has a large impact on the performance of the sewage source heat pump. In order to avoid energy waste, it is more appropriate to adopt a 30% guarantee rate and an A3 pump unit flow rate, under which the solar collector efficiency is 50.18%, the proportion of solar heating of crude oil is 47.16%, the average temperature of crude oil is 42.59 °C, and the COP of the sewage source heat pump is 4.65. Further increases in the COP of the wastewater source heat pump can be realized by increasing the temperature of the wastewater supply. The results of this study provide a valuable reference for the optimization of crude oil storage heating systems.

The Pondakan Alam Sari ornamental fish cultivator group has approximately 50 types of ornamental fish cultivated for domestic and foreign commodities. Market demand for ornamental fish tends to increase yearly, but the market wants stable prices. This price stability is a dilemma for ornamental fish cultivator groups. One of the determinants of the selling price of ornamental fish is operational costs, especially electricity costs. The increase in basic electricity tariffs causes operational costs to increase. Electricity is used to power the circulating water pump 24 hours non-stop daily. This circulating water pump is very important for producing oxygen in the water. If there is no oxygen in the water, ornamental fish will die. To reduce operational electricity costs, the community service team built a DC electricity system sourced from solar energy so that the circulating water pump source no longer uses PLN electricity. This community service program aims to reduce operational electricity costs by building a DC electricity system sourced from solar energy and an IoT-based monitoring process. The implementation method consists of two stages: (1) building physical capital through a solar energy electricity source and DC pump installation and (2) creating a DC electrical parameter monitoring system with the Blynk IoT platform. The evaluation technique was carried out by comparing planning with the progress of implementing activities. The results and implications of activities include the availability of DC electricity sources from renewable energy, namely solar cells with a power of 960 WP, installing 10 DC pumps, and an IoT-based DC electrical parameter monitoring system. Operational costs in managing an ornamental fish business can be reduced by 46% from before using renewable and IoT-based energy. This result will certainly increase the profit margin of ornamental fish farming.

A multi-agent digital twin–enabled decision support system for sustainable and resilient supplier management

Industry 4.0 is reshaping the manufacturing landscape, bringing about revolutionary changes in both product manufacturing and collaborative interactions among value chain constituents. Within the manufacturing value chain process, sustainable and resilient supplier management is recognized as a strategic endeavor that drives value creation, such as enhanced product quality, risk mitigation, and improved organizational reputation. Sustainable and resilient supplier management processes necessitate the integration of multiple criteria, efficient supplier coordination, and adaptability to evolving challenges. Nonetheless, conventional supplier management practices primarily rely on expert judgment, focus on the present situation, and lack a robust decision validation mechanism, leading to a limited capability to constitute proactive managerial decision-making under uncertainty. This paper introduces a digitally enabled decision support system for facilitating an intelligent and customized supplier management process in dynamic and complex environments. The system leverages stratified fuzzy decision-making techniques to account for the potential impacts of future events. Additionally, it integrates multi-agent digital twin technology to provide a reliable validation mechanism for assessing the effectiveness of supplier development strategies. The effectiveness of the proposed system was demonstrated through its successful implementation within a multinational solar water pump manufacturing company, highlighting its promising potential for practical applications.

Unraveling Farmers' Purchasing Behavior of Solar Water Pumps Using the Theory of Planned Behavior

India is an agricultural country with hottest temperature and moderate humidity, where it is believed that some states receive the maximum solar energy, one of them is the state of Rajasthan. The need for power has expanded over the past few decades’ which is leading to significant increase in environmental degradation as even today, more than 70% of energy needs is fulfilled from fossil fuels. Higher dependence is resulting in higher cost and environmental degradation. Implementing solar pumps cannot only help us to overcome energy deficits but also increase agricultural productivity which help us to reduce pollution produced by thermal and diesel sources. The present study is based on first-hand information gathered from 498 farmers from five blocks of rural region of Rajasthan (India). To understand the factors influencing the behavior of farmers towards green technologies, theory of planned behavior model has been applied. Data were collected using questionnaire/schedules, the sample size was chosen using convenience sampling, and were then examined further using SPSS and AMOS. In order to understand the elements of the TPB model and predict farmers’ behavioral intention towards adoption of solar water pumps, confirmatory factor analysis (CFA) and structural equation modelling (SEM) were applied in the study. The proposed research fills in the gap in the literature by performing an empirical study on farmer’s adoption behavior and offering insight about variables influencing farmers purchase intention and behavior of farmers towards solar water pump. Results from the study will be more useful to the policy makers to design effective strategies in order to achieve energy sufficiency without adversely affecting the environment.

Unleashing the potential of solar irrigation in Bangladesh: key lessons from different implementation models

The transition to solar-powered irrigation in South Asia offers an opportunity to cut greenhouse gas emissions and reduce dependency on expensive diesel. However, appropriate institutional and financial models are required to scale up this technology. Three different solar irrigation pump (SIP) implementation modalities coexist in Bangladesh, providing a good opportunity to evaluate and gain insightful knowledge on the solarization process. These conclusions are also applicable to neighboring countries dealing with comparable problems. The three models are (i) community-managed SIP model, (ii) individual ownership model, and (iii) fee-for-service model. In this article, we argue that the fee-for-service model involving a market-based approach and public-private partnership is the most promising in terms of addressing two main challenges in solarization, i.e. high capex financing requirement and generation of sufficient demand. In terms of achieving equity in SIP access and groundwater sustainability, all three models have their respective pros and cons. However, the financial sustainability of SIPs is under threat due to the significant project costs. It is imperative to expedite the integration of SIPs with the national power grid while implementing supportive government policies. This includes enhancing buy-back tariffs and introducing net-metering options to ensure long-term sustainability.

A Single Stage Photovoltaic Solar Pumping System based on the Three Phase Multilevel Inverter

This paper presents a study of a single-stage DC-AC converter for a solar water pumping application. The topology was based on solar panels connected to a new structure of a three-phase multilevel inverter through DC-bus capacitors. The inverter offers simplicity, requires fewer components compared to conventional ones, and provides optimal voltage and current waveforms with reduced harmonics, eliminating the need for filters. The applied control technique aimed to stabilize the input DC-bus voltage, extract the maximum power using a simple MPPT algorithm, and enhance the efficiency of the water pump through scalar V/f control, regardless of weather changes. A simulation was conducted using the PSIM software, considering a variable daily climate scenario. The results obtained demonstrate the efficiency of the system in extracting energy with optimal torque and current for the pump compared to a classic design based on a three-phase H-bridge inverter.

О возможности продления сроков эксплуатации автозимников с использованием возобновляемых источников энергии

It is hard to overestimate the role of winter roads in the land logistics of the northern regions. In recent years, climate change has not only significantly reduced the service life of winter roads, but also made them less predictable. This forces transportation to increase in intensity, often at the expense of safety, or to stop that suddenly, leaving vehicles and equipment unused for long periods and disrupting project deadlines. Therefore, extending the service life of winter roads and reducing dependence on local weather conditions is a very urgent task. To solve it, we considered the possibility of applying our previously proposed method of thermal stabilization of frozen ground using solar panels and heat pumps, and estimated the associated costs. Our calculations have shown that it is possible to extend significantly the service life of unpaved winter roads, up to year-round use, in the case of using the most lightweight road pavement without creating a cushion. The approach can contribute to solving a whole range of problems of sustainable development of the Russian Arctic territories by creating transport and energy corridors.

Optimal techno-economic energy coordination of solar PV water pumping irrigation systems

In this study, a water pumping photovoltaic system (WPPVS) provided with a water storage tank is introduced to supply freshwater for drip irrigation in Farafra oasis, Egypt. A multi-objective K-means clustering based on non-sorting genetic algorithm is utilized to minimize both the loss of water supply probability and the total annual costs including capital and running costs. Due to the variability of the water flow rate, a techno-economic energy coordination is developed with particular attention to avoid vibration of water pumps. The economic feasibility is based on the tomato crop yield against the total cost of the drip irrigation system. Sensitivity analysis for dynamic head, crop price, and interest and inflation rates is conducted. At specific dynamic head of 6 m, the results revealed that the optimal design of the WPPVS pumps 10220 cubic meter of water for irrigation through the developed energy coordination against 18575 cubic meter with pump vibration which saves 45 % of the pumped water. This reflects its effect on a decrease of the pumped water for all dynamic head values. Furthermore, the vibration avoidance strategy allows the pump to operate at lower dynamic heads above the water threshold level in the well, which is not possible with the presence of vibrations.

Evaluación Tecno-económica de alternativas para calentamiento doméstico de agua para la ciudad ecuatoriana de Cuenca

INTRODUCTION. Homes in the Andean region of Ecuador, due to the relatively cold ambient temperature, require energy services such as hot water in a daily basis along the year. In that context, the preferred technologies used for such purpose run on LPG, mainly, due to its low cost as it is highly subsidized. This situation poses certain challenges for the energy policy of the country. OBJECTIVE. This case study aims to discuss more sustainable alternatives to obtain hot water for household use in the context of the Andean city of Cuenca. METHOD. Firstly, solar and meteorological data has been processed to characterize local conditions. Then, different technologies able to provide hot water have been simulated. Further, an economic analysis was performed to determine costs per unit of energy required. RESULTS. The use of subsidized LPG reduces the real cost of water heating between 47% and 72% depending on the daily levels of consumption. In the event of a subsidy removal, electric tankless water heaters, along with reduced electricity tariffs, become competitive for levels of consumption up to 120 liters per day. For higher levels of consumption solar thermal systems or heat pumps may become viable only when providing rebates DISCUSSION AND CONCLUSIONS. The presence of benefits of scale among levels of consumption need to be regarded when designing incentives for energy services such as domestic hot water.

Designing and performance assessment of a hybrid CAES based CHP system integrated with solar energy and heat pump

In this paper, a novel combined heat and power system based on compressed air energy storage (CAES) coupled with a solar collector system was introduced. Based on the significant effect of heat pumps in improving heat quality, the heat pump and solar energy are adopted to improve energy storage and economic performance. To maximize the effective utilization of solar energy, the energy dispatch scheme of the system has been studied in detail. The system's performance under multiple operating conditions has been evaluated. Moreover, to further explore the optimization potential of the solar-coupled compressed air energy storage system, important factors such as the distribution proportion of thermal oil and key temperature have been emphasized and analyzed. The optimization of key temperature, distribution proportion of thermal oil, and operating conditions can enhance the cascade utilization of energy, and also provide a comprehensive approach for the design and optimization of the proposed system. Parametric sensitivity analysis was first conducted. Results show that the charging pressure should be close to the discharging pressure and there is no local optimal distribution ratio for the thermal oil. The optimal condition under design constraints is also determined, the system power efficiency, energy efficiency, and power-to-power efficiency reached 0.297, 0.851, and 0.570, while the levelized cost of storage of the system is 0.527 $/kWh, the dynamic payback period is 9.516 and simple payback period is 7.428 under the specified conditions. The output power and heat in 6 h of discharging are 3829.50 kWh and 7147.48 kWh, respectively, with a total investment cost of 7373.57k$. Moreover, the exergy and economic analyses were then conducted. The highest exergy losses were caused by the solar collector system with 29.01% of the total loss. The turbines and the solar system also had the highest economic cost, indicating directions for further optimization.

Theoretical cost and energy optimisation of a 4th generation net-zero district heating system with different thermal energy storage technologies.

A model was used to simulate and optimise a speculative district heating (DH) system for an existing urban area in Loughborough, UK. Heat was supplied using only renewable heat sources (RHS) with long and short duration thermal energy storage (TES) systems used to address mismatch between heat generation and demand. For an 18-month simulation period, a) building heat loads, b) heat generated, c) heat flow to and from stores, and d), heat losses from the stores and network were calculated using hourly weather data, network and building characteristics. RHS included evacuated-tube solar thermal collectors (ETSTCs), and ground and air source heat pumps powered by electricity generated by solar-photovoltaic (PV) and Wind turbines (Wind). The effect of long-term TES system volume and charging temperature on the calculated DH system cost per dwelling, and the calculated DH system energy efficiency was assessed. The minimum cost of the DH system was obtained by modifying the capacity of installed Wind and PV, while ensuring that heat demands were met in every hour of the simulation. A minimum cost per dwelling of £12,278 was predicted with an energy efficiency of 84.84 % for a long term TES volume of 15,000 m3 and temperature of 60 °C.

Simulating Potential Impacts of Solar MajiPump on the Economy and Nutrition of Smallholder Farmers in Sub-Humid Ethiopia

Irrigation is widely considered a potential means to improve agricultural productivity, nutrition, and income, as farmers can carry out farming and production year-round. However, the feasibility of irrigation technologies is highly dependent on the long-term economic return farmers achieve. Solar-based irrigation could address the challenges of underinvestment in irrigation within Africa. Evidence on the economic viability of the adopted solar pumps such as MajiPump is very scant and focused on ex post evaluation. This study evaluated the income and nutritional feasibility of solar-powered irrigation using the MajiPump in sub-humid Ethiopian highlands using the farm simulation (FARMSIM) model and compared it with the manual pulley system. Results from the FARMSIM model show that farmers’ adoption of Maji solar pump technology to grow vegetables is economically feasible with financial support such as credit or loan for initial and capital investment to acquire the pump. The average profit under the solar MajiPump, drip irrigation, and conservation agriculture was 3.6 times higher than that of the baseline scenario. While the pulley technology provides the same amount of irrigation water to grow vegetables, its feasibility is limited due to high labor costs and time, estimated to be more than seven times the baseline. The simulation results show that the alternative scenarios’ nutrition level has improved relative to other scenarios and met the minimum daily average nutrition requirement level for proteins, iron, and vitamin A but fell short in fat, calcium, and calories. The results suggest that farmers who adopt improved small-scale irrigation technologies (solar MajiPump and drip system) have a higher potential to increase production and income from irrigated crops and improve their nutrition if part of the income generated is used to purchase supplemental food for their nutrition.

Pemanfaatan Teknologi Pompa Portabel Tenaga Surya untuk Sistem Irigasi Kebun

The Community Service Program (PKM) aims to solve the problems faced by farmer group partners, such as: (1) unequal financial capabilities in each member of the farmer group, (2) less good agricultural yields if smoke appears during the long dry season, and (3) high operational costs because they depend on fuel consumption for the plant watering process. The implementation of core activities in this PKM program consists of two stages, namely; (1) solar cell pump assembly training to provide solutions for partners who are not familiar with solar-powered portable water pump technology and still depend on using fuel pumps as a means of watering plants, and (2) solar cell pump operation and maintenance training to provide solutions for partners who cannot operate and maintain solar-powered portable water pumps.
