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.

Eine der wichtigsten Voraussetzungen bei der Bestimmung der Wasserquelle ist, dass diese während der Trockenzeit nicht versiegen darf. Der Wasserstand von Teichen schwankt im Allgemeinen relativ gering, dennoch ist es notwendig, den niedrigsten Wasserstand und die Wassertiefe während einer Dürrezeit zu bestimmen. Bei Tiefbrunnen müssen Brunnentiefe, Brunnendurchmesser, Wasserstand, dynamischer Wasserstand und Wasserabgabe ermittelt werden. Bei Flüssen müssen während der Hochwassersaison der niedrigste Wasserstand, die Wassertiefe und der höchste Wasserstand ermittelt werden.

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.
