Study on induced aeration for fishery fields using floating SPV

Abstract

The soluble oxygen content in the water is affected by oxygenation, which is a vital factor for commercial fishery fields. The soluble oxygen content is the prime factor for the fishes grown in those fields, and most probably, the fields are located in remote locations where electricity could not be accessible. Photovoltaics (PVs) are becoming more popular as a renewable resource. The electric power generated by solar panels can be utilized to run the aerators in order to aerate the fishery fields that are isolated and disconnected from the primary power system. A 100 Wp floater solar PV (SPV) modules for powering five numbers of DC aerators are used in the present investigation. The efficiency of floated solar panels was monitored by measuring sun irradiation, PV temperatures, output power, and current. The amount of oxygen in the water before aeration was around 3.2 mg/L, however after deploying floated solar panels and aerator, the level of soluble oxygen was raised to 4.4 mg/L.
