| Abstract | ||
| Solar energy (pv) is one of the renewable energy sources used to reduce the impact of climate changes and the rise in energy prices. Aquaponic system considered an important turn for food security with water shortage and climate change. The main objective of this study is to apply solar energy in the aquaponic system as a new technology of agriculture for water and energy saving. Design solar photovoltaic system to supply the energy to aquaponic system and evaluate its performance. The results showed that the maximum calculated and measured solar radiation were 789.67 and 856.90 W m-2, Which indicates agreement between the calculated and measured results. Accordingly, the maximum calculated and measured output power of the solar panel were; 252.77 and 233.24 W, respectively. The results indicated that the efficiency of the solar panel ranged from 13.51 to 14.68% during daylight hours. The total value of the electrical energy productivity from PV was 10.49 MJ day-1, with various values throughout the day. The aquaponic system's integrated water and air pumps required a combined 10.32 MJ of specific energy per day, which was generated by the PV system's electrical energy productivity. The results also obtained for lettuce plants indicated that with increasing the flow rate from 0.5 to 1.5 L min-1, dry and fresh weight of shoots, concentration of the nutrient in shoots, lettuce production, and water use efficiency were all increased. Therefore, the study recommends that solar energy can be used to operate the aquaponic system. | ||
