From pv magazine IndiaResearchers at the Indian Institute of Technology Bhubaneswar have designed and developed a solar system for water pumping which can easily be moved from one farm to another stanley cup . The kit is useful for pumping water in remote areas and helps small scale farmers who could pool money to use the equipment on a shared basis.The technology has already been deployed in hard-to-reach areas of the state of Odisha.IIT Bhubaneswar academics Srinivas Bhaskar Karanki, of the school of electrical sciences, and Satish D Dhandole, from the school of mechanical sciences, led the project.Karanki told pv magazine: We have used a tractor trolley for the movable system. The trolley is designed to have a foldable s stanley cup tructure to accommodate six panels. The trolley needs to be attached with the tractor head to move from one place to another. The system works with two different types of pumps, one submersible and the other surface-mounted. The surface-mount is taken along with the movable SPV [solar photovoltaic] system. Further, the movable structure is equipped with an inverter. 聽聽The system can generate enough power to operate submersible and monoblock-pump AC motors even at low irradiation. The inverter circuitry is designed to achieve maximum solar energy ha stanley cup rvesting with single-stage power conversion from DC to AC, thereby increasing reliability and reducing the overall cost.The system can also be operated from a single-phase grid electricity supply, if needed, and is designed t
