The implementation of on-grid PV systems was conducted to ensure a continuous supply of electricity. This article discusses implementing an on-grid PV system in a fish farm that requires a continuous electricity supply. Continuous electricity is used to power the aeration system. The aeration system is critical in determining whether or not fish farmers can harvest well. An electric motor drives the water wheel in the aeration system, circulating oxygen in the fishpond. Based on the design, operation, and economic parameters, a comparison is made between the proposed system, namely the PV system, and the current system, namely the grid with a diesel generator as a backup. The nominal discount rate, diesel fuel price, and grid reliability level have all been subjected to sensitivity analysis. The Hybrid Optimization of Multiple Energy Resources software was used for the study. The results show that the on-grid PV system can continuously provide electricity to meet the demand for fish farming. The proposed system has a net present cost that is 20% lower than the net present cost of the current system. The cost of energy generated by the on-grid PV system is also 27% less than the cost of energy generated by the current system. Changes in fuel prices do not result in changes in net present cost for all levels of grid reliability to produce continuity in electricity supply. The nominal discount rate strongly influences the net present cost, the higher the nominal discount rate, the lower the resulting net present cost.

Sustainable Development Goal 13 is an activity committed with the intention of stabilizing greenhouse gas (GHG) levels in the environment to stop potentially harmful human meddling with the climate system. GHG are released into the environment from various non-renewable energy sources of power generation and many industries that cause extensive damage to the environment. Some countries have begun to implement various pollution prevention strategies, such as power generation from renewable energy sources, which emit no greenhouse gases (GHG) or CO2. This study focuses on an analysis of GHG emission reduction along with the financial feasibility of a grid-connected 100MW PV solar system. This study uses RETScreen software to evaluate the GHG emissions reduction analysis as well as a financial analysis of the system. The annual electricity supplied to the local grid of the proposed PV power plant is 137,481MWh. The cost of reducing CO2 emissions has a positive impact on the overall cumulative cash flow of the proposed system.
