A floating photovoltaic system for fishery aeration

Abstract

Photovoltaic panel as a producer of renewable energy is increasingly being utilized. The electrical energy produced by photovoltaic panel can be used for aeration in fish ponds located quite isolated and far from the main electricity grid. Aeration is important for fishery because it affects the dissolved oxygen level in the water. The system uses two units of 50 Wp floating solar panels and four units of DC aerator of 12 Volt/0.28 A. The measurement of solar irradiance, solar panel temperature, output voltage and current was conducted to monitor floating solar panel performance. Dissolved oxygen level measured in the water without aeration was 3-3.9 mg/L while after using floating photovoltaic panels to supply the electrical energy for aerators, dissolved oxygen level in the water was increased to 4.1-4.8 mg/L.
