The Solar Pump for Spray Crops is an eco-friendly and cost-effective agricultural system designed to provide an efficient spraying solution using renewable energy. The system utilizes a solar panel as the primary power source to generate electrical energy, which is regulated through a charging circuit and stored in a rechargeable battery. An additional charging circuit connected to a transformer serves as a backup charging source when solar energy is unavailable. The stored energy powers a DC water pump, which is used for spraying pesticides, fertilizers, and water on crops. This system reduces dependence on conventional electricity and fuel-powered sprayers, making it suitable for rural and remote farming areas. By utilizing clean solar energy, the project helps lower operating costs, reduces environmental pollution, and supports sustainable agricultural practices. The proposed system offers reliable operation, easy maintenance, and improved efficiency in crop spraying applications.     Objectives
