How to Make a Small Aquaponic System Using a Solar Water Pump

Aquaponics is a sustainable and efficient way to grow plants and fish in an integrated system where these organisms have a symbiotic relationship that benefits both. 

Creating an aquaponics system is an ideal solution for those who want to grow their own food but have limited space or resources. It is a sustainable system that combines hydroponics and aquaculture to grow plants and fish in a closed loop. Using a solar pump to power your aquaponic system is a sustainable and cost-effective way to keep it running. It's a great way to produce fresh food at home, and with the use of a solar pump, it can be made even more environmentally friendly and energy-efficient.

In this article: We discuss the benefits of an aquaponics system and then walk you through the steps to make a small aquaponic system using a solar pump.

Benefits of a Solar Aquaponic System:

  1. Energy-efficient: A solar aquaponic system uses renewable energy from the sun to power the water pump, which makes it energy-efficient and cost-effective in the long run.
  2. Sustainable: The closed-loop system of aquaponics is inherently sustainable as it uses less water and fewer resources than traditional farming methods.
  3. Organic: The use of organic materials and the lack of harmful chemicals in the system make it a healthier option for growing food.
  4. Year-round production: A solar aquaponic system can be set up indoors or outdoors and can produce fresh food year-round.
  5. Educational: A solar aquaponic system is a great way to teach children about sustainable food production and the importance of environmental stewardship.

How to Build a Small Aquaponics System Using Solar

Step 1: Plan your Aquaponic System

Before starting, it is important to have a clear plan of what you want to achieve with your aquaponic system. Determine the size and location of the system, the type of fish and plants you want to grow, and the amount of sunlight your location receives. This information will help you choose the appropriate solar pump to power your system.

Step 2: Gather Your Materials Needed

  • 2 fish tanks (one for the fish and one for the plants)
  • Grow bed
  • Gravel
  • Solar Water pump
  • 12V solar panel
  • Tubing (PVC pipes and fittings)
  • Battery, Charge controller, and timer (optional)
  • Plants
  • Fish

Step 3:  Build or Select Your Fish Tank

The first step is to build the fish tank or choose a large enough tank to hold the plants and fish you want to raise. The size of your fish tank will depend on the number of fish and the size of your grow bed. Place your fish tank in a sunny area, as the solar panel will need direct sunlight to operate. A 10-20 gallon tank should be sufficient for a small aquaponic system.

Step 4: Create Your Grow Bed

The next step is to build the grow bed. The grow bed of the aquaponic system is where the plants will be grown. The grow bed can be made of wood, plastic, or any other material that's suitable for holding soil. Your grow bed should be shallow and filled with a layer of gravel. Fill the grow bed with gravel and add water until it's about 1-2 inches below the top of the gravel.

Step 5: Connect the Fish Tank and Grow Bed

The fish tank and grow bed need to be connected to allow the water to flow between them.

Start by installing the fish tank and grow bed in a location that receives adequate sunlight. Place the grow bed above the fish tank so that gravity can pull the water down. Connect the two using tubing (use PVC pipes and fittings to connect the two tanks), making sure the water can flow freely between the two.

Step 6: Install the Water Pump and Solar Panel

Install the water pump in the fish tank and connect it to the PVC pipes. Connect the solar water pump to the solar panel. The water pump will circulate the water from the fish tank to the grow bed. Install the 12V solar panel in a location that receives plenty of sunlight. Connect the solar panel to the charge controller, battery, and solar water pump. The charge controller will prevent the battery from overcharging.

Next, install the solar pump to circulate the water between the fish tank and grow bed of your aquaponic system. The Solariver 360GPH solar water pump is a great option for small-scale aquaponic systems. It is a submersible pump that can be powered by a 12-watt solar panel, making it an energy-efficient and eco-friendly choice. 

Step 7: Add Plants and Fish

Once the system is set up and the pump is connected, add fish and plants to the system. The fish will provide the nutrients for the plants, and the plants will help to clean the water for the fish. Add plants to the grow bed, making sure they are well-suited for aquaponics. Some popular plants for aquaponics include lettuce, basil, and mint.

Then, fill the tank with water and add the fish to the tank. You’ll want to choose fish well-suited for aquaponics, such as tilapia, catfish, or trout. Ensure you provide enough food for your fish and maintain a healthy environment for them. The plants will absorb the nutrients from the fish waste and the fish will have a clean environment to live in.

Step 8: Monitor Your System

Maintaining a healthy and productive aquaponic system requires regular monitoring and maintenance. Check your system regularly to make sure everything is running smoothly. Keep an eye on your fish tank's water level and the grow bed's pH level. Make sure to clean your grow bed and replace the water in your fish tank regularly.

It is important to keep the solar panel clean and debris-free to ensure optimal performance of the solar pump. Regularly check the connections and tubing to ensure there are no leaks or blockages.

Step 9: Harvest and Enjoy

Once your aquaponic system is up and running, you can start harvesting your own fresh, organic produce and fish. Not only is this a cost-effective and sustainable way to grow food, but it is also a fun and rewarding hobby that can be enjoyed by the whole family.

In conclusion, a small-scale aquaponic system using a solar pump is a great way to grow your own food using sustainable and eco-friendly methods. Proper planning, installation, and maintenance allow you to enjoy fresh produce and fish from your backyard. 

In conclusion, a solar aquaponic system is an excellent way to grow fresh food at home while reducing your carbon footprint.

Using a solar pump to power your aquaponic system is a great way to save money on energy costs and reduce your environmental impact. Get started on your system today and enjoy the benefits of fresh, healthy food grown right in your home. By following these steps, you can create a small aquaponic system that is both sustainable and rewarding. Happy farming!
