这篇文章报道了曼塔纳尼岛上光伏太阳能系统的潜在用途。这个岛在动植物方面有它的吸引力，以及它当地社区的独特性。该岛电力供应状况微乎其微，当地供电商仅提供两台发电机组，仅供应18时至6时的电力。这项研究的动机是假设如果目标居民能够获得更好的电力供应，他们就可以产生更高的收入，提高他们的生活水平。本研究旨在了解太阳能资源状况，估算基本电力负荷，并对居民家庭寄宿企业进行技术经济分析。利用Solargis收集和分析了关于太阳能资源的地球同步卫星数据。用电负荷是根据居民的日常活动和主要电器的使用情况计算的。通过确定计算投资回报率和回收期的关键参数，进行了技术经济分析。结果表明，曼塔纳尼岛具有实施光伏系统的巨大潜力，年总太阳能和峰值太阳小时的估计值分别为1.447兆瓦时/平方米/年和4.05h。月总太阳能变化最小，仅为61.3Wh/m2。计算的电力负荷为7.454千瓦时/天，技术经济评估表明，投资回报为3600马币/年。然而，回收期的价值根据所花费的资本成本的价值而不同。就本研究的资金成本而言，可实现的最短和最长回收期分别为2.78年和13.89年。这一计算与装机容量为2.2千瓦的光伏系统是一致的。
This article reports on the potential use of a photovoltaic solar system on Mantanani Island. This island has its attractions in terms of flora and fauna as well as the uniqueness of its local community. The electricity supply status of the island is minimal, and the local electricity provider only provides two units of electrical generator that only supply energy from 18:00 to 06:00. This study is motivated by the hypothesis that if the target resident can obtain a better electricity supply, they can generate higher income and improve their standard of living. This study aims to identify the status of solar energy sources, estimate the basic electrical load, and conduct a techno-economic analysis of homestay enterprises of residents. Geostationary satellite data on solar energy resources were gathered and analyzed using Solargis. The electricity load was calculated based on the daily routine activities of the residents and usage of primary electrical appliances. Techno-economic analysis was done by determining the key parameters to calculate the return on investment and payback period. The results showed that Mantanani Island had great potential for implementing a photovoltaic system, by the estimated value of the total annual solar energy and peak sun hour of 1.447 MWh/m2/y and 4.05 h, respectively. The variation in total monthly solar energy was minimal, with a range of only 61.3 Wh/m2. The calculated electrical load was 7.454 kWh/d. The technoeconomic assessment showed that the return on investment was MYR 3600 per year. However, the value of the payback period varies according to the value of the cost of capital spent. Regarding the cost of capital of this study, the shortest and longest payback periods achievable were 2.78 and 13.89 years, respectively. This calculation is in line with a photovoltaic system with a capacity of 2.2 kWp.
