SOLAR POWERED VERTICAL AQUAPONICS SYSTEM: This is an original design I made to maximize the yield of a 12’x12′ foot space and use gravity to minimize the energy used for irrigation and nutrient delivery.
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′ tall at the top of the solar panel and approximately 13′ at the top spiral. There is 6 foot wide plastic fish growing tank at the base.
The water from the 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 and the crops 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 approx. 1080 square feet. 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.
Cost to build this system is about $5k including tank, materials, pipe, pump, and solar power system.
This will produces nearly 10,000 pounds of food annually, meaning 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.
