System Outlook Of Solar Water Pumps

It is difficult to significantly improve the efficiency of silicon solar panels in a short period of time. Although the second-generation thin-film solar cells and the third-generation organic solar cells have obvious advantages in cost, compared with the mass production of silicon solar panels Not competitive yet. In the future, silicon solar panels will still occupy a large share of the market. Therefore, the future research and development direction of solar water pump systems should focus on the following three aspects:
(1) Develop high-efficiency water pumps and motors to improve the high-efficiency area of the motor and water pump under a wide range of speed and flow changes and reduce the system water pumping threshold power. Develop low-cost, high-reliability intelligent controllers to improve performance matching between components and cope with changing climate conditions, thereby improving system dynamic quality and overall efficiency. At the same time, we will improve the development and promotion of comprehensive technologies for the complementary utilization of small and medium-sized wind, light, heat and other energy sources.
(2) A general method for long-term performance prediction of solar water pump systems under changes in climate, light, water level, water demand and other factors and a system design method based on dynamic changes. Establish databases in different regions to gradually replace the method of using static average estimation.
(3) With the decrease in panel prices and the development of small and medium-sized solar systems, in the future, on the basis of optimizing panel power, the evaluation of system operation reliability should be increased to improve the long-term operation reliability of the system and the stability of water supply.
