Solar Power Plants (SPPs) offer the potential for clean and sustainable energy, but their independent operation faces challenges due to their dependence on weather conditions, which can lead to energy supply fluctuations, necessitating the use of conventional electrical power. One solution that enhances energy supply reliability is the deployment of on-grid SPPs. On-grid SPPs are systems connected to the public electrical grid, allowing integration with conventional energy sources. This research aims to investigate the optimization of on-grid SPP designs within the context of the livestock industry, employing a simulation-based approach utilizing PVSYST. The livestock industry demands consistent energy supply for day-to-day operations encompassing lighting, temperature control, livestock feed processing, and various other electrical requirements. PVSYST simulations are utilized to tailor an SPP system to meet the specific needs of an Indonesian livestock industry, accounting for variables such as solar panel orientation, solar module types with power ratings of 500Wp and 450Wp, system capacity, and the potential integration with the specific power demands of the livestock facility. Simulation results reveal that the solar radiation in the area reaches 1947 KWh/m2, while the annual energy demand for the livestock industry in that region averages 19,035 MWh. To fulfill this energy requirement, solar panels with a power rating of 500 Wp are required, with the optimal solar module tilt angle being 15 degrees. This configuration entails 44 panels organized into 2 strings, with a single inverter rated at 20 KW (AC). In this setup, the energy generated through the solar panels amounts to 38.58 MWh per year, while the energy supplied to consumers totals 30.6 MWh. Performance ratio analysis demonstrates the highest PR achieved at 82.81%. This research establishes a solid foundation for livestock industry stakeholders looking to adopt on-grid Solar Power Plants (SPPs) as an environmentally friendly, sustainable, and highly efficient energy source.
