Nowadays, energy and environmental issues have become major issues of concern to governments. As a kind of renewable energy, the utilization of solar photovoltaic power generation has developed rapidly. With the increasing scarcity of fresh water resources, and there are still many areas that are not covered by the power grid in developing countries, there are problems with difficult access to electricity and water. Therefore, the research on photovoltaic water pumping systems with both practical and social value has Significance. Based on the analysis of the characteristics of photovoltaic panels and the working principle of the water pump, this paper develops a new type of photovoltaic water pumping system. The system uses photovoltaic cells as the power supply of the system and uses a sensorless DC brushless motor as the driving motor of the water pump. , Using PIC16F877A microcontroller as the main control chip of the system.
