| dc.description.abstract | This project presents the design, development, and implementation of a solar-powered automatic
water-pumping system intended primarily for rural, remote, and off-grid applications where access
to reliable electricity is limited or unavailable. The main objective of this system is to provide a
sustainable, energy-efficient, and cost-effective solution for water supply using renewable solar
energy. The proposed system integrates several key components, including a photovoltaic (PV)
solar panel for energy harvesting, a rechargeable battery storage unit for energy backup, a charge
controller for efficient power management, and a voltage regulation circuit to ensure stable system
operation. In addition, an automatic control mechanism is implemented using a float switch and
relay module, which enables the system to start and stop the water pump automatically based on
the water level in the storage tank. To enhance the safety and durability of the system, a low
voltage cutoff (LVC) module is incorporated to protect the battery from deep discharge conditions,
thereby extending battery life and improving overall system reliability. The entire system is
designed to operate on direct current (DC) power, eliminating the need for grid electricity as well
as reducing dependence on conventional fuel-based pumping systems. The performance of the
system has been evaluated through experimental testing under practical conditions. The results
indicate that the system operates reliably, efficiently harvests solar energy, and successfully
performs automatic water tank filling without manual intervention. The use of renewable solar
energy not only reduces operational costs but also minimizes environmental impact by eliminating
carbon emissions associated with fossil fuel-based pumps. Overall, the proposed design is simple,
scalable, and economically feasible. It can be effectively implemented for domestic water supply,
small-scale irrigation systems, and other agricultural applications, especially in rural and
developing regions. The system offers a sustainable alternative to conventional water pumping
methods and contributes to the promotion of green energy technologies. | en_US |
