Solar pumps for aguaculture & river maintenance
Pond aeration involves increasing or maintaining the oxygen level in a pond to improve water quality.
Pond aeration facilitates the process of removing pond pollutants and oxidizing the pond. This process enables aquatic insects, fish, and aerobic bacteria to break down lifeless organic matter.
If you’re involved in aquaculture or need to maintain rivers and want to avoid increasing operational and maintenance costs, then a solar-powered aeration pump system is an ideal choice
Solar Pond Aerator
Many find it challenging to install electric aeration systems in isolated ponds or lakes due to the lack of economical access to power sources.
This dilemma is particularly vivid, especially in farm ponds, golf course lakes, rainwater reservoirs, and other private water bodies.
Fortunately, even if your pond cannot access electricity, there are other feasible ways to aerate it economically and sustainably.
The emergence of solar alternatives means you can harness the free energy of sunlight, using solar panels to aerate the pond.
If you’re committed to reducing your ecological footprint and using only renewable energy, then a solar pond aerator is what you need. The operating costs of this system are very low and suitable for almost any location
Benefits of Solar Pond Aerators
1.No need for electricity – These aerators do not require electricity to operate as they harness energy from sunlight through solar panels
2.Reduced energy loss – These aerators are more efficient as there is minimal or no energy loss during short-distance energy transfer, unlike systems with significant energy loss
3.Odor control – Aeration with solar pond aerators eliminates odors from dams. Typically, odors are caused by anaerobic bacteria thriving in low-oxygen environments. Oxygenation of the dam helps eliminate these bacteria, thereby eliminating odors
4.Reduction of pests and mosquitoes – Pests and mosquitoes thrive in stagnant water rich in bacteria. These insects find it difficult to breed in continuously circulating water. This is why we strongly recommend using solar pond aerators to eliminate such insects
How does Solar Pond Aerator Work?
- When sunlight shines on the surface of the solar panels, the movement of electrons generates direct current, which is transmitted through connected wires to the pump controller
- The pump controller acts as the system's brain, utilizing advanced technology and sensor inputs to rotate the aerator. Through this process, water temperature is balanced, dissolved oxygen in the pond is increased, and excess nutrients are broken down, providing you with clear water.
How to Choose the bestsolar pond aerator
The best one for you will depend on the size and depth of your fish pond. Ideally, larger ponds will need aerators with higher power capacity and features that will allow the sufficient distribution of oxygen throughout the pond.
How to choose a solar panel?
The power of the solar photovoltaic panel array is recommended to be 1.3 times or more than the power of the water pump.The voltage of the solar photovoltaic panel array needs to meet the voltage range of the water pump.
Example:
Solar Aerator
Model: DSA15-4.5-48-370
- Pump power: 370w
- Best input voltage: 60-90v
- Maximum open circuit voltage: 105v
Requirements for solar photovoltaic panel array: power ≥ 370w*1.3 (that is, power ≥ 481w)
- VMP voltage>60v
- VOC voltage<105v
Solar panel:
- power 330w
- VMP voltage 37.26v
- VOC voltage 45.64v
2 solar panels in series:
- power 330w*2=660w
- VMP voltage 37.26v*2=74.52v
- VOC voltage 45.64v*2=91.28v
In this case, the power and voltage requirements of the pump can be satisfied, so this solar photovoltaic panel array scheme is acceptable.
Is a battery necessary?
The battery is not necessary, if you need to use it at night or in rainy weather, you can choose Hode AC/DC hybrid solar submersible pump.
How to Choose Batteries?
If batteries are required, a charge controller must be connected. The voltage output of the batteries must match the voltage of the pump. The connection method of the charge controller is shown in the diagram
How to select water pump extension lines?
The solar water pump comes with a cable of 5 meters. The length can be customized according to your actual needs. Customers can also extend the cable themselves.
Notes for selecting cables:
- 1. Select waterproof cables.
- 2. Select 3-wire or 4-wire cables（including the ground wire).
- 3. 2.5sq cables are recommended below 50m; 4sq cables for 50m-100m; 6sq cables for 100m-200m.
