Design of Solar Power Generation System For Watering Mustard Plants In The Garden Area of Land 600 Sub-District Medan Marelan

Abstract

Solar power plant (PLTS) is a power plant that works by utilizing renewable energy in the form of solar power as an energy source. This research proposes the design and a solar power generation system (PLTS) that is integrated with an automatic mustard plant watering system. The main objective of this research is to investigate the effectiveness of using solar energy as an energy source to run an automatic watering system for mustard plants and to find out how the influence of sunlight intensity, temperature, and humidity on the energy produced by photovoltaics. The experimental method is carried out by designing and building a PLTS system connected to a water pump for watering chili plants. The results of this study show that the amount of power produced by solar panels depends on the intensity of solar radiation that hits the surface of solar panels. Solar panels used as an alternative energy source with a maximum power of 50 Wp have an efficiency of 13.83%. In this study, the maximum sunlight intensity of 1009.62 W/m2 is able to produce a voltage connected to the load up to 14.84 V and a current of 1.40 A and the power generated reaches 20.78 Watt, with a solar panel temperature of 42°C. And based on the average power entering the battery, a 12 V 7.5 Ah battery can be fully charged within 420 minutes. This shows that the integration of PLTS in the watering system is able to provide adequate, stable and sustainable energy supply. In conclusion, this study indicates that the application of solar power in mustard plant watering systems has the potential to increase energy efficiency and crop yields, while reducing environmental impacts. With a deeper understanding of the technology and energy management, similar systems can be applied to larger-scale farms to support the sustainability of the agricultural sector.
