What are the main components of the solar pump system?

The system is mainly composed of a photovoltaic array, a photovoltaic water pump inverter and a water pump. Solar cells can be matched with the corresponding power according to the requirements of different heads and daily water consumption, also known as photovoltaic water pumping system. The system operates fully automatically, without manual guarding, saves energy storage devices such as batteries, replaces storage with water storage, and directly drives the pump to lift water.

The main component features include:

1.Photovoltaic array

It is composed of a plurality of solar cell modules connected in series and parallel, absorbs solar radiation energy, converts it into electric energy, that is, solar power generation, and provides power for the whole system.

2.Photovoltaic water pump inverter

Real-time control and adjustment of the operation of the system, when the sunshine is sufficient, the system is rated for operation. When the sunshine is insufficient, the minimum operating frequency is set to ensure the full application of solar power.

3.The pump

Water can be extracted from deep water sources such as deep wells or rivers and lakes, injected into water tanks, or directly connected to irrigation or fountain systems. DC pumps, AC pumps, centrifugal pumps, axial pumps, mixed flow pumps, deep well pumps, etc. can be used.

Stable and reliable solar energy resources. The number of sunshine days in the year should be no less than 2200h; the total solar radiation in the whole year should be no less than 1000k W.h/(m2.a). The water quality and water supply of the water source should meet the corresponding standards and requirements; the water source should not be too far away from the photovoltaic water pumping unit; the distance between the water pumping unit less than 2k W and the water source should not exceed 10m, and the distance between the water pumping unit not less than 2k W and the water source should not be suitable. More than 20m.

The nature of the water source and the amount of water produced are important basis for the construction and investment of the pump system. Pumps used in different water sources are very different. Generally, submersible pumps are required in the deep underground. If the sediment content in the water is large, the sewage pump should be used. When there are good water inlet conditions, single-stage and multi-stage centrifugation are used. Pumps, etc. One of the most important conditions for determining the source of water is that the water source does not dry during the dry season. In general, the water level in a pond varies relatively little, but the minimum water level and water depth at the time of drought need to be determined. For deep wells, it is necessary to determine the depth of the well, the diameter of the well, the water level, the moving water level and the water output. The river needs to determine the lowest water level in the dry season, the water depth and the highest water level during the flood season.
