Aquaponics is an incredibly sustainable and efficient way to grow food. It involves growing plants and fish in one system; fish waste feeds the plants and the plants clean the water for the fish. Aquaponic growing results in higher yields than traditional growing while using fewer resources.

Below is an original solar-powered vertical aquaponic system design concept I created to maximize the yield of a 12’x12′ foot space, using gravity to minimize the energy used for irrigation and nutrient delivery.


Vertical aquaponics system

The system is a vertical, spiral aquaponics growing system powered by a single 250-watt solar panel and a small DC water pump/filter system. A single DC pump makes the whole thing work.

The tower is 15 feet tall at the top of the solar panel and approximately 13 feet at the top of the spiral. There is 6-foot wide plastic tank at the base of the system for growing fish.

The water from the fish tank is pumped up through a small PVC pipe to flow slowly down through the plant crops growing in the spiral growing tray.

Upon harvest, water flow is increased. The harvest gate at the bottom end of the spiral is removed so the crops can flow down the spiral, making harvesting easy.

The growing bed tray is approximately 360′ feet long by 3 feet wide, creating a grow area of approximately 1080 square feet. The maximum yield per square foot is approx 7.65 lbs of food annually, or 8262 lbs of veggies annually. This does not include the total yield of fish produced in the tank, which is about 1000 fish, or 1500 pounds annually.

The cost to build this system (at the time of this writing) is about $5k including the tank, materials, pipe, pump, and solar power system.

This concept can produce nearly 10,000 pounds of food annually. That means at about $1 per pound national average retail, that’s approximately $9762 in revenue, for a profit of $4762 for the year.

Or you could just produce enough food for your entire family for the year.

I like your idea of Solar powered vertical aquaponics system. My big concern is that how can I reach the garden food on the top on 13 feet high for gathering harvest foods? It would be difficult to reach up to 13 feet with a ladder. It is seemed to be an impractical way for this method of gathering foods on unreachable height by hands without using a ladder.

Please contact me directly if you have the time. I would love to expand this idea and create a vertical farm using this technology and design. I will be putting my dream up on as it grows. I would love to have your input about the project. Thanks, Pam
