Solar Powered Water Pump for Irrigation – Buying Guide
Our Solar Pumps Effective for Irrigation?
Yes, they are. In fact, they are often recommended for various types of irrigation, such as farm or small garden irrigation. They also happen to have a low operating cost compared to their competitors. Since they run on solar energy, your energy costs are drastically lowered with solar powered water pumps. Maintenance and damage repairs caused by harsh weather such as hail storms are the only operating costs you will have to bear to maintain the efficiency of the solar panels.
These solar powered pumps rely on the power generated when sunlight hits solar panels. So, no more high electricity bills. With the sun being a renewable energy source, they are 100% eco-friendly.
What to Look for While Buying A Solar Pump for Agriculture
1. Maximum Flow
What we understand by flow rate is essentially the volume of water the pump can push out per unit time, usually counted in minutes. This flow rate differs from one pump to the other, so make sure you note it while deciding on one.
Each kind of irrigation requires a certain flow rate, so some pumps might not push water out at the required irrigation rate you want, so it is always best to confirm the desired flow rate of the type of irrigation you are going for and then check the flow rate of the product to find out if they meet the necessary standards.
2. Head Lift
The maximum lift of a pump refers to the maximum vertical distance water can reach after being pushed by your pump. The water coming out of the water sources and heading to the drainage source will cover a certain distance. That’s what the maximum lift refers to. This information becomes crucial if the drainage destination is above the ground since not all pumps might meet the requirement.
3. Solar Pump Capacity
Solar pumps require PV panels to operate, but it is important to note that pumps can only function properly if the solar panel generates ample power to get them up and running. With the inclusion of a PV panel, you do not have to think about panel capacity.
However, if you plan to buy the panel separately, do pay attention to the PV panel capacity. Verify the wattage of your pump beforehand to ensure things go just right. Confirm that the panel produces the same power as the rating of the pump at the very least. It’s recommended to get panels that produce more power than the pump’s power rating. This takes away the worry of power loss.
4. Motor Quality
The quality of the motor is always a concern, no matter the kind of pump you are going for. You need to get a quality check on the solar powered water pump’s motor before making a concrete decision about your purchase. A weak motor inevitably means quicker corrosion and lesser longevity.
Ensure your pump’s motor is sturdy, stable, and certified sufficiently for prolonged use. These are important metrics to check off when pump motors are concerned.
5. Ease of Installation
Whichever pump you decide to purchase, it should first and foremost be easy to install. Sure, you can get professional help during installation, but the best course of action is to get an easy pump to install. You can save a lot of money on installation and damages resulting from poor installation by keeping an eye out for easy installable solar powered water pumps.
6. Corrosion Resistance
Your water pump will constantly be exposed to water and air irrigation, especially its metallic components. So, make sure your water pump is coated with metal alloys such as stainless steel to avoid rust and corrosion. While purchasing pumps, make sure you go for one with built-in corrosion-resistance features to avoid durability issues in the near future. In any case, stainless steel pumps are the best bet.
7. Power Source Flexibility
While it’s true that powering your solar powered water pump is eco-friendly, do not forget that the sun won’t always be around. So during those times, your pump might struggle to pump power if it is not operated with other power sources. The good news is that many solar powered water pumps also work on batteries to save you from this particular trouble. You will even find some with electric cords to help during times when the sun does not help in powering your pump.
Yes, eco-friendliness is the number one feature making solar powered water pumps best for irrigation, but there are other benefits as well. Make sure you know what you are looking for and go for a pump that has a sufficient flow rate as per your needs.
Verify the pump’s flexibility, durability, efficiency, lift, and ease of installation and maintenance before committing to one. With that being said, the list provided in this article might help you choose the perfect water pump for you. Good luck!
