Solar PV water pumping (PVWP) principle
In order to demonstrate the techno-economic feasibilities, pilot facilities are installed in typical areas, achieving benefits from grass productivity improvement, farmers’ income increase, ecological restoration and CO2 emission reduction. The applications of PVWP technology can improve the management of water resources, realize efficient utilization of solar energy and water resources, and achieve sustainable development in rural and pastoral areas. Meanwhile, the multi-functions of M-PVWP, including power generation and water supply for human being and livestock, can effectively improve the pastoralist’s standard of living.
In the project, the Swedish partners mainly focus on the R&D of solar photovoltaic systems, the assessment of CO2 emission reduction and the economic benefits of ecological restoration. The Chinese partners contribute to the water resource modeling and advanced irrigation technologies. Based on the combination of PVWP technology and the water resource management, the effects on the water resource and the ecological system of the grassland are evaluated.

 Innovations in the Project
The project focuses on technology innovations, economic and ecological performance improvement. The technical innovations involve system modeling and optimization and integration with the available water resources and crop water demand. Field tests have been conducted for validation of the dynamic simulations and system monitoring, especially focused on the effects of the system operation on the environment. The benefits of using PVWP systems compared to the traditional diesel driven system and electric grid have been identified in term of CO2 emissions mitigation and soil carbon sink enhancement. The implementation of PVWP systems can achieve optimal economic return. In order to scale up for the large implementation of the PVWP technologies, a new innovative business model is being developed to integrate the social network and ICT technologies to maximize co-benefits and engage all stakeholders including decision-makers, project developers, investors, and farmers.
