The objectives of this study are: 1) To know and analyze the amount of solar energy potential available on Padang Tikar Island and to study the distribution of solar radiation intensity throughout the year as the basis for planning the solar power plant. 2) Identify and analyze technical and environmental factors that affect the design of a hybrid Solar Power Plant (PLTS) system with a combination of Diesel Power Plant (PLTD) and energy storage system (battery) that is in accordance with the energy needs of the community on Padang Tikar Island. And 3) Analyzing the influence of the use of solar tracker systems on increasing the efficiency of electricity generation in the solar power plant system and examining the technical and economic limitations in its application at the project site. The research method is by means of observation, calculation and literature study. The data analysis in this study is as follows: Analysis of Solar Energy Potential and Solar Radiation Distribution. Analysis of Technical and Environmental Factors in the Design of Hybrid Solar Power Systems . Analysis of the Influence and Limitations of Solar Tracker. The results of the study concluded that Padang Tikar Island has high solar energy potential with an average radiation of 5.3 kWh/m² per day, supporting the development of solar power plants with a capacity of ±2.8 kWp for daily needs of 10 kWh. To meet the total energy needs of the community of 700 kWh/day, a 978 kWp hybrid solar power plant system with an 875 kWh battery and PLTD as a 10% reserve was designed, resulting in an LCOE of Rp4,099/kWh which is more efficient than diesel. The application of single-axis solar trackers can increase efficiency up to ±25% or 34,560 kWh/year, with an additional investment of IDR 300 million and a payback period of 6 years, suitable for application due to flat topography and high solar intensity, although it requires regular maintenance and extreme weather mitigation. The solar power plant project on Padang Tikar Island aims to replace 600,000 kWh/year of diesel electricity (510 tons of CO2/year) with a 460 kWp solar power plant. Although solar power plants have indirect emissions of 36 tons of CO2/year from their life cycle, the project will reduce annual net carbon emissions by 474 tons of CO2. Over 25 years, the total avoided emissions reached 11,850 tons of CO2. These emission reductions not only provide environmental benefits, but also have the potential to generate revenue from carbon trading, with an estimated USD 118,500 over 25 years if the carbon price is assumed to be USD 10/ton. This financial potential is crucial for the feasibility and sustainability of the project in the long term.
