Evaluation of Off-Grid Solar Power Plant Implementation on Biofloc Fishery System

We have implemented a 1500Wp off-grid solar power plant (SPP) in biofloc fishery system. Through this paper, we try to provide an overview of the SPP’s effectiveness based on data collected from April 2022 to September 2022. The analysis is carried out to obtain the average daily, monthly and predicted annual energy yield. The analysis is continued to the average daily and monthly irradiation as well as the performance ratio. From an economic aspect using net present value (NPV), we present the calculation results which show that the off-grid SPP system is not a profitable investment. It can be profitable if there is at least an 8% increase in electricity tariff per year.
