This is a solar powered aquaponics system that has been created in Hawaii. It uses an IBC Tote structure for the grow bed and the fish reservoir. It appears to be a fully homebuilt system that uses a DIY solar panel to charge a 12 volt marine battery. The battery runs both the DC pump and a DC air pump. The electrical items are housed in a Rubbermaid plastic tote unit to protect it from the elements.
Solar Powered Aquaponics System Runs Without Bell Siphon
Since this is located in Hawaii, there is little worry about freezing or other cold related issues. This means the entire solar powered aquaponics system is located outside with no greenhouse protection.
The solar panel is homebuilt and soldered from DIY plans and also has a switch to turn the water pump on and off on a regular cycle. The Solar panel is not felt to be strong enough to run the system on a continuous basis should a long rainstorm occur. It seems his safe zone is to be able to operate the system without added sun power for three days.
The videograpgher, boohaus describes the video:
An aquaponics system run completely off of solar power. A homemade solar panel charges a battery and in turn powers an air and water (bilge) pump. An Arduino (overkill, I’m sure, but there’s more to it than just that) with a relay on the board controls the water pump – 3 minutes on, 17 minutes off. No siphon system, just fill and drain. Currently I have white tilapia and green swordtails in the pond and lettuce, cherry tomato, chives, and rosemary plants in the black cinder grow bed. This is my first system, so I’m learning a great deal.
The panel produces enough voltage (~14V under load) to charge a 12V battery and by solar cell specs produces ~2A. The water pump is on a timer because the panel does not collect enough to power the water pump and air pump 24/7. I am currently in the process of adding another water pump.
