Description of the project

This project is to develop and demonstrate a prototype of integrated Photovoltaic (PV) water pumping technology for grassland and farmland conservation with sustainable water resource management. By targeting at scale up of the technology, laboratory tests, field study, and in-depth analysis will be applied. A PV water pumping system will be installed in a selected site based on solar energy, water resource, and land conditions. Engineering design and modification of key components such as PV, water pump, irrigation pipes techniques will be conducted. The grass productivity and other products of high economic value will be investigated. Environmental and social benefits will be assessed and policy and institutional issues will also be addressed. The results will provide a technically robust and economically viable system and a business model for commercial scale-up in real applications.
