Solar Pump Widely Used, Will Windmill Pump be Replaced Soon?


2020-04-23

Windmill pump which have a long history, is one of the earliest widely pumping methods for human and livestock drinking water, agriculture and forestry pasture irrigation. Traditional windmill pumps are mainly purely mechanical, with complex structures of special wind wheels, transmissions and pumps, high failure rates and low water lifting efficiency.

Solartech solar pumping technology was used as early as 2001 for water-saving irrigation of road protection forests in the Taklamakan Desert. In 2014, Solartech introduced permanent magnet solar pumps to the market, which with the features of less solar panels needed, screw pump to adapt to high head, special solar pumping inverter control system can guarantee water efficiency when solar energy is weak. After more than 5 years of promotion in the market, it has been accepted and recommended by more and more farmers and herdsmen.

The renovation project for using solar pump to replace windmill water pump in Guatemala was completed in February 2020. The project selected SPM600HS permanent magnet solar pump, equipped with three 275W solar panels, the total head of 20 meters and the average daily waterflow is 18 tons. The owner of the original windmill pump has been in disrepair. Affected by the wind season, the waterflow is very low. Solartech solar pumping system completely solved the problem of stable water supply. What is more, the cost of the project used solar pump is only one-tenth of the cost of mechanical windmill pump.

In recent years, thanks to the unique rich solar sun conditions and the continued reduction in the cost of PV modules, various types of solar powered system solutions and products here by the government's recommended support and user acceptance and recognition. From the first set of permanent magnet solar pumping system project installation and operation in 2014, Shenzhen Solartech and local distributor has been working together for more than 5 years, successfully installed more than 300 sets of solar powered water pumping system in Guatemala. These solar pumping systems, spread throughout 22 provinces of Guatemala and are mainly used for agricultural irrigation and drinking water for livestock, the power from 400W to 22kW, greatly improving the conditions of local agricultural irrigation and livestock watering. The rapid development of the solar water conservancy industry in Guatemala has significantly increased agricultural cultivation production and livestock farming, which directly benefiting more than 3 million farmers and herders.

Solartech permanent magnet solar pumps have the characteristics and advantages of less solar panel needed, high reliability, and the the system can work and pumping water when the solar energy is reduced. The design life of solar pumping inverter is 10 years. High head optional screw pump and big flow optional centrifugal pump. The system is simple to install and easy to set up. The 400W system can be powered by only one solar panel. The data communication interface enables remote monitoring. Embedded encryption enables system to realize the business model of installments. The optional dedicated Solartech solar pumping control box can be connected to the battery pack and stores the electricity generated by solar panels when it is not required to meet other electrical needs.

Solartech PM series solar pumping inverter using its own patented dynamic VI maximum power point tracking (MPPT) algorithm, high reliability, conversion efficiency reaches 98%. Solartech Permanent magnet pump apply the DC brushless motor which is using Rare Earth permanent magnet material excitation, without excitation coil and excitation current, compared to the same capacity asynchronous motor, efficiency significantly increased 5%-20%, with high efficiency and simple structure of super advantage.

Solartech solar pumping system, that is, ready-to-use, no need to set up a power grid; automatic operation, no need to pay electricity bill; in-place water use, no need to build canal; water storage instead of energy storage, no need battery, and environmental protection and energy conservation without any pollution.
