Although the second-generation thin-film solar cells and third-generation organic solar cells have obvious cost advantages, they are not competitive with the large-scale production of silicon solar panels. In the future, silicon panels will still occupy a large share of the market. Therefore, the future research and development direction of solar pump system should focus on the following three aspects:
(1) Research and development of high-efficiency water pumps and motors to improve the high-efficiency zone range of motors and pumps under a wide range of speed and flow changes and reduce the power of the system water threshold. Develop low-cost, high-reliability intelligent controllers to improve the performance matching between components and cope with changing climatic conditions, thereby improving the dynamic quality and overall efficiency of the system. At the same time, 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) The general method of long-term performance prediction of solar pump system under the change of climate, light, water level, water demand and other factors, and the system design method based on dynamic change, establish databases in different regions, so as to gradually replace the method of using static average estimation;
(3) With the reduction of panel prices and the development of small and medium-sized solar energy 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.
