Abstract:
The paper aims are to implement an aquaponic system powered by solar energy, in order to reduce the energy and create an innovative greenhouse that uses a symbiotic relationship between fish and plant. The cycle of this symbiosis consists in the conversion of the remains coming from the fish in nitrates, which are eaten by the plants and the purified water goes back to the fish and the cycle continue. The system does not use traditional soil, but a tanks systems with clay balls, that ensure a good living space for bacteria that transform the debris in food for plant. The aquaponic system is placed in a greenhouse beside the monitoring system. This system is compound of temperature and humidity sensors, a light sensor, a water temperature sensor and a LCD monitor for keeping the greenhouse at a range of temperature and humidity specific for the plants and fish. The greenhouse has an usage in an apartment so the size of system is 40x20x60 cm with a separated solar system. The greenhouse has a layered structure, with the greenhouse walls placed on the top, bellow is the plants tank and at the bottom is placed the fish tank. This structure meets two principles of ergonomics through space economy and energy economy, only a pump is used for transporting the water from the plant to the fish. The necessary energy per day is about 30W so a panel of 50W will ensure the total energy. The solar system consists of a solar panel, a converter, and a solar battery, for power the system day and night. The entire system is monitored and controlled by an Arduino microprocessor. This microprocessor controls the system water circuit, temperature and humidity ensuring the necessary condition for the plant and fish survival.
