Water is the most fundamental need for better yield in agriculture. Worldwide, diesel and electricity are typically used to pump water which contributes to atmospheric pollution. Besides, a power outage affects the irrigation process badly. Without water, the crop may wither away, causing a substantial economic loss. This paper discusses the resilience of a solar PV system during a power outage. HOMER Pro software was used to perform the techno-economic analysis of solar-based irrigation for four major divisions of Bangladesh, while 1-hour power outage was assigned in REopt lite to model the survivability of the system against the grid outage. The simulation outcomes showed that the energy cost is $0.1496/kWh, $0.1502/kWh, $0.1557/kWh, and $0.1576/kWh for Rajshahi, Sylhet, Dhaka, and Chattogram, respectively. About 45% of excess electricity can be stored after fulfilling all requirements. The system is more economical than a microgrid-based water pumping system and a diesel-based system, and the photovoltaic system is technically and economically suitable to pump water if the nearest grid connection is impossible. When connected to the main utility grid, the system can survive without grid power for several hours, subject to daytime outages.
水是农业提高产量的最基本需求。在全球范围内，通常使用柴油和电力来抽水，这会导致大气污染。此外，停电会严重影响灌溉过程。没有水，庄稼可能会枯萎，造成巨大的经济损失。本文讨论了太阳能光伏系统在停电期间的弹性。使用 HOMER Pro 软件对孟加拉国四个主要地区的太阳能灌溉进行了技术经济分析，同时在 REopt lite 中分配了 1 小时的停电时间来模拟系统对电网停电的生存能力。模拟结果表明，拉杰沙希、锡尔赫特、达卡和吉大港的能源成本分别为每千瓦时 0.1496 美元、0.1502 美元、0.1557 美元和 0.1576 美元。在满足所有需求后，大约 45%的剩余电力可以存储。与微网供电系统和柴油供电系统相比，该系统更经济，并且在无法与最近的电网连接的情况下，该光伏系统在技术和经济上适合抽水。当与主电网连接时，该系统在白天停电的情况下，可以在没有电网供电的情况下持续数小时。
