Solar-powered pumps have a lower environmental impact compared to pumps powered by IC engines or utility electricity. These pumps are best suitable for reservoirs and irrigation systems.
Eco-friendly
Since the sun provides the energy, an external power source isn't necessary, which means a solar-powered water pump will work in remote places and areas without access to a power grid.
Solar-powered water pumps have very few mechanical parts, which lessens the chances of components needing repairs. They can last for many years without requiring maintenance.
Engineers aren't required to assemble or install solar-powered water pumps. They have few components and can be installed easily by local people.
Solar-powered water pumps provide a reliable water source because it doesn't require electricity.
Submersible solar pump have the ability to lift up to 650ft of water and can install in large wells. As long as the well water is more than 20ft above the surface, these pumps operate directly to turn off batteries, solar panels, and in some cases, electricity.
These types of solar pump are most commonly used in deep water and undrilled areas. These pumps also use for livestock watering, pond aeration, home water systems, irrigation, pressurization, and well pumping. The maximum recommended pump depth is 50m.
The surface solar pumps are used in streams, storage tanks, shallow wells, or ponds. When the well water supply depth is 20ft or less from the ground, you should use a surface solar water pump.
Due to physics, the maximum suction lift of a surface pump cannot exceed approximately 8 metres. They are ideal for accessible water sources as they are optimised for higher flow rate.
In arid and semi-arid areas, the lack of water resources makes it difficult to irrigate crops. The Solar Powered Pump Drives system is used to irrigate crops, achieving the purpose of low energy consumption and environmental protection. At the same time, the cost of pumping water is reduced, and the economic benefit is significant. The photovoltaic water pump system has broad application prospects and significant social, economic and ecological benefits in commercial crops and farmland irrigation.
In areas with soil erosion, solar energy is used to pump water from rivers ashore without the need for power supply to irrigate soil erosion-proof vegetation on both banks and hillsides. Solar Powered Pump Drives systems play an important role in the governance of soil erosion protection.
Photovoltaic water pump system is also widely used in afforestation, returning forest and grassland, curbing the spread of desertified land and desertification grassland management, protecting and restoring desertification grassland grassland vegetation, comprehensive management of small watersheds and water sources, construction of water-saving irrigation projects, small water conservancy and water conservation projects, farmland and artificial grassland irrigation, etc.
Drought and water shortage will cause serious damage to grasslands, large areas of forages will dry up, and animal husbandry production will be severely impacted. Livestock in pastoral areas will be killed or injured due to lack of grass and water. At present, grassland irrigation mainly relies on groundwater, and the utilization of groundwater is restricted by two factors, one is the limitation of water resources, and the other is the limitation of energy and power. These areas are scattered with scattered settlements, inconvenient transportation, and difficult to supply energy. In addition, the power grid construction has caused energy shortage due to high line losses and large spans, which makes it impossible to solve the problem of water-lifting power. The Solar Powered Pump Drives system combines the characteristics of rich solar energy resources and long sunshine time in the grassland, and effectively uses the solar panel to convert the solar energy into electricity, drives the water pump to extract groundwater, and transforms the natural grassland into artificial grassland.
From rain-fed agriculture to solar
Moving from rain-fed agriculture to a solar powered water pump will increase your farm's resilience to changing weather patterns, droughts, and seasons. Irrigating through drier periods of the year means that you will have longer growing seasons, and sometimes even grow an extra harvest, depending on the climate where you are.
Fuel pumps are often praised for their high flow rates which is something which must be considered when switching to solar. A solar pump will require a large PV array to pump equal amounts of water. However, water conservation and efficiency techniques such as using low-pressure sprinklers or drip irrigation can reduce the amount of water you need to deliver to your plants. You do not need to swap like for like. One of the largest benefits of moving away from a dependence on fossil fuels is that your farm profits are less reliant on the often unpredictable price of fuel because solar energy is free. You also do not need to travel to fill a petrol can anymore.
Visually check for shading of the collectors during the day (mid-morning, noon, and mid-afternoon) on an annual basis. Shading can greatly affect the performance of solar collectors. Vegetation growth over time or new nearby construction may produce shading that wasn't there when the collectors were installed.
Check all nuts and bolts attaching the collectors to any support structures for tightness. Watch for corrosion on steel parts- and clean and paint if necessary.
Verify that pumps or blowers (fans) are operating. Listen to see if they come on when the sun is shining on the collectors after mid-morning. If you can't hear a pump or blower operating, then either the controller has malfunctioned or the pump or blower has. The problem is often the starting capacitor, which can be replaced without replacing the pump or motor.
The propylene glycol antifreeze solutions in liquid (hydronic) solar heating collectors need to be replaced periodically. The pH (acidity) and freeze point of the fluid can be measured with hand-held instruments and replaced if out of specification. It's a task best left to a qualified technician. If water with a high mineral content (i.e., hard water) is circulated directly in the collectors, mineral buildup in the piping may need to be removed by adding a de-scaling or mild acidic solution to the water every few years.
