System Outlook For Solar Water Pumps

( 1) Develop high-efficiency pumps and motors to improve the range of high efficiency zones under a wide range of speed and flow changes and reduce the system water threshold power. Develop low-cost, high-reliability intelligent controllers to improve performance matching between components and cope with changing climatic conditions, thereby improving system dynamic quality and overall efficiency. At the same time, improve the development and promotion of integrated technologies for the complementary utilization of small and medium-sized wind-light-heat and other energy sources;

( 2) A general method for predicting the long-term performance of solar pump systems under changes such as climate, light, water level, water demand and other factors, and based on the system design method under dynamic changes, establish databases in different regions to gradually replace the method of static average estimation;

(3) With the reduction of the price of panels and the development of small and medium-sized solar energy systems, in the future, on the basis of optimizing the power of the panels, the evaluation of the reliability of system operation should be increased to improve the long-term operation reliability of the system and the stability of water supply.
