The nature of the water source and the amount of water output are an important basis for the construction and selection ofsolar water pumpsystems. The solar water pumps used by different water sources are quite different. Generally,submersible pumpsare required for water sources deep underground. The water source is surface water. Surface pumps are generally used. If the sediment content in the water is large, a sewage pump should be used.

Una de las condiciones más importantes para determinar la fuente de agua es que no se seque durante la estación seca. Generalmente, el nivel de agua de los estanques presenta variaciones relativamente pequeñas, pero es necesario determinar el nivel mínimo y la profundidad del agua durante la sequía. En el caso de pozos profundos, es necesario determinar la profundidad, el diámetro, el nivel, el nivel dinámico y el caudal. En el caso de los ríos, es necesario determinar el nivel mínimo, la profundidad y el nivel máximo durante la temporada de inundaciones.

Solar modules are the power core of the entiresolar water pumpsystem. The selection and configuration of solar modules are the main factors that determine the cost performance ofsolar water pump systems. According to the light intensity and temperature characteristics of solar modules and the performance evolution characteristics of the life cycle, the general photovoltaic module capacity is 1.3 to 1.6 times larger than the power required by the pump motor, which is a relatively reasonable configuration. The specific size needs to be determined according to the head and pump selection. The photovoltaic array needs to be installed in a place with a stable foundation and good sunlight.
