Aiming at the problems of water temperature and water level control system of conventional solar water heater and low solar thermal control efficiency, this paper developed an AT series single-chip solar water heater control system for rural areas. In this paper, the detailed design of hardware and software is presented, and the method of evaluating the collector efficiency is simplified by the temperature rise rate and solar irradiance of the collector plate. The software compensation algorithm we adopted can effectively reduce the impact of different water quality on water level measurement and improve solar thermal control efficiency. It is found that the control system designed in this paper has the characteristics of low cost, high safety, and strong practicability.
