Abstract

Solar-powered water driving scheme (SPWDS) has been successfully employed as a practical solution to guarantee reliable water supply in various hilly regions without electrical infrastructure. The Water Supply Systems / Schemes (WSS) focus on using pumping systems for delivering potable water to the community but face practical difficulties and financial hurdles at different implementation stages. These challenges encompass the practical complexities, the absence of non-renewable energy sources, and ongoing expenses for consumable and non-consumable items incurred during the water project's execution and maintenance. The present research study evaluates the performance of four water supply systems in Nepal which use solar energy as their primary power source. The key performance indicators are assessed, including the functionality index for facility distribution. Additionally, the research aims to evaluate the feasibility of transitioning from non-renewable to sustainable renewable energy source to achieve net zero energy consumption. This evaluation concentrates explicitly on calculating the cost-effectiveness index as a key metric. A proportional analysis is undertaken to evaluate the cost-benefit of the SPWDS, considering both the potential advantages and challenges associated with these initiatives. The present study affirms the technical feasibility and economic viability of operating a WSS using renewable and eco-friendly solar energy as the power source. This finding opens avenues for reducing energy consumption and contributes significantly to developing a policy framework to for tapping solar energy.
实施太阳能水泵系统的成本效益分析 - 案例研究
太阳能供水系统(SPWDS)作为一种实用的解决方案,已成功应用于没有电力基础设施的丘陵地区,以保证可靠的供水。供水系统/计划(WSS)的重点是利用水泵系统为社区提供饮用水,但在不同的实施阶段都面临着实际困难和资金障碍。这些挑战包括实际操作的复杂性、不可再生能源的缺乏,以及供水项目实施和维护过程中产生的消耗品和非消耗品的持续支出。本研究评估了尼泊尔四个以太阳能为主要能源的供水系统的性能。对关键性能指标进行了评估,包括设施分布的功能指数。此外,研究还旨在评估从不可再生能源过渡到可持续可再生能源的可行性,以实现净零能耗。该评估明确将成本效益指数作为关键指标进行计算。考虑到与这些举措相关的潜在优势和挑战,进行了比例分析,以评估 SPWDS 的成本效益。本研究证实了利用可再生、环保的太阳能作为动力源运行供水系统的技术可行性和经济可行性。这一发现为减少能源消耗开辟了道路,并为制定开发太阳能的政策框架做出了重大贡献。
