The following buying guide will help you choose the best solar water pumps
Primarily, four types of solar pumps are available based on the source of water and technology used:
1.Surface pumps –
These pumps can be used if the groundwater level is not more than ten meters of reach. Hence, it is advisable to use these pumps when the water has to be drawn to long distances and the water source is shallow. It can be placed beside lakes, ponds, water tanks, etc. They might not draw water but can supply water to long distances.
2. Submersible pumps –
These pumps can draw water from bore and areas with water table below 10 meters. They are used to draw water from bores and wells. These are a little expensive than the surface pumps but are more appropriate for drawing water from sources with a lower water table.
3. DC pumps –
Direct current pumps are available which directly work on a battery or without battery. They are easy to operate and are more energy-efficient. They can be used for small to medium functions, such as small irrigation projects, etc. These are more energy-efficient when the power supply is low.
4. AC pumps–
The alternating current pumps require an inverter. This means that direct current gets converted into alternating current. They work slower than DC pumps but can be more efficient.
The following factors need to be kept in mind before buying a solar water pump
- Pump Efficiency: The efficiency of a pump means its ability to change solar energy into electric energy. The efficiency of a pump is measured in LMP and needs to be checked and may vary from one machine to another.
- Flow Rate: It actually means the volume of water lifted or supplied by the pump in a given time unit.
- Location: Your location of where you want the pump to be installed should also be kept in mind.
- Water Requirement: The amount of water required in a day should also be considered.
- Pump Controllers: Some solar pumps may require special pump controllers that work automatically in low light. If a battery is being provided, the controller may not be needed.
- Drop Pipe: The pipe that connects the pump to the surface (top of a well, etc.) is called a drop pipe. It is advisable to use a narrow, polythene, flexible pipe to avoid pump problems. A large pipe will lift water slowly and cause sand deposits.
- If you want your fountain to work for as long as possible, then you should opt for night pumps. These pumps come with battery backup at a higher cost. This feature will help store energy for later use. (At night or prolonged cloudy days)
How to increase the efficiency of your solar pump-
- Cleaning the pump regularly will ensure better water flow.
- Ensuring that the water quality is good helps to increase the efficiency of the pump.
- Do not mount fountain heads with large heights.
- The solar panels should be placed in the direction of the sun to obtain maximum sunlight.
- Clean solar panels regularly to make sure that they take in maximum sunlight.
Pros and Cons of Solar water pumps
Since we intend to help you choose the best solar water pumps for your pond, we need to look into some gains and some drawbacks of these pumps.
- The solar pond pumps are not only economical; they are easy to install and take less space. They are less noisy too and can be installed without worrying about the wiring.
- These pumps do not work for long hours despite of battery backup and are meant for small features.
After going through the above information, you must be well aware of which solar pump to buy for your needs. Now, we will answer some of the widespread solar pump concerns that people have. The following questions give a complete understanding of solar water pumps.
What are solar pumps?
The pumping system almost remains the same as our old pumping systems, but these are powered by solar panels instead of electricity. The entire system consists of solar panels, inverter batteries, and a motor pump. When the solar panel it hit with light, it produces a direct current. This current converts itself into the power that sets the pump in motion.
In some cases, an inverter is installed to get AC. Hence, the DC pump does not require an inverter.
Is there any possibility of relocating a pump after it has been set up at a place?
Of course, relocation of water pumps is possible. In the case of small pumps, it is quite easy, but the relocation of larger pumps and panels is not smooth. It is a complicated and expensive job. One has to shift panels on portable platforms.
Is there any particular decisive factor in selecting the location of the pump?
The location of panels has been discussed clearly. They should be installed at places with maximum sunlight. Also, they should be installed at places where there is very less dust.
The stands of the panels should be placed at even surfaces. The pumps should not be placed very far from the panels. They should be set up at places with high water tables so that the lift height for the pump is less.
Can extreme weather conditions affect solar panels? What safety measures can be taken during such conditions?
Most panels come with safety measures. But in extreme weather conditions like storms or cyclones, the stands of these panels may get damaged. In order to avoid this damage, the array can be placed horizontally.
A lightning strike can be lessened by installing an external lightning protection system. This is because lightning can cause major damage to solar panels.
What maintenance is required in the case of solar pumps?
Solar pumps require minimal maintenance once installed. The cleaning of solar panels regularly is the key to increasing the durability of these pumps.
Can flow rate be improved by adding more solar panels to the pump?
The flow rate can be increased by adding the extra panels to the controller, but we need to take care that the voltage limit of the pumps is not surpassed. The maximum flow rate of a pump cannot be increased, but the extra panel will help it run efficiently during cloudy days or early morning or evening hours.
7. What is the difference between an off-grid and on-grid solar rooftop kit?
An off-grid rooftop kit recharges the battery and the power is later used mainly during the night. In the on-grid system, the electricity produced is sent to the main grid and the power is taken from the grid during the night time for use.
It can be concluded that solar power systems can be used in gardens ranging from 10 watts up to 100 kilowatts. The best solar water pumps for gardens are available with fountain features. They have the security of running at night, also with the help of battery backup and LED lights.
Solar water pumps are economical, eco-friendly, and spare us the hassle of wiring and looking for power outlets. They are especially useful where finding power outlets is difficult. Choosing a solar water pump is definitely a smart move, and the above guide will help you pick an option for yourself.
