Abstract
This paper presents the experimental development and evaluation of an autonomous photovoltaic-powered aquaculture system designed for small-scale fish farming in isolated areas. The system integrates renewable energy generation, automated control, and real-time monitoring to ensure energy self-sufficiency and environmental sustainability. The experimental setup, consisting of a 6 kWp photovoltaic array (15 panels of 400 W each), a 24-unit 24 V battery bank, and a diesel generator for emergency backup, was tested at INMA Bucharest over a two-year period. The installation supplies power to essential aquaculture subsystems, including water recirculation, aeration, automatic feeding, lighting, and surveillance. Experimental data showed that the photovoltaic system fully met the average daily energy demand of 3.35 kWh, with hourly peaks of approximately 255 W, maintaining functionality even during winter periods with low solar radiation (0.8–1.0 PSH/day). The hybrid configuration ensured up to 48 hours of energy autonomy and reliable operation under variable climatic conditions. Fish farming under a polyculture regime was also tested, representing an integrated biological mechanism for self-cleaning that enhances the overall sustainability of the aquaculture system. Results demonstrate that autonomous hybrid systems represent a viable solution for sustainable aquaculture, improving energy efficiency, reducing environmental impact, and supporting the viability of small-scale fish farms in remote regions.
