Analisa Perencanaan Pembangkit Listrik Tenaga Surya Atap dengan Sistem Hybrid di PT. Koloni Timur

Abstract

This study discusses the Planning of a Rooftop Solar Power Plant with a Hybrid System at PT East Colony Kudus. The model is set as a PLTS whose solar panels are adjusted to the roof area of the building. This PLTS is functioned as a new renewable energy resource (EBT) in the form of a hybrid between PLTS and PLN's electrical energy source, this is done to help supply electricity. Parameters determined include: roof area, solar panel capacity, inverter capacity, battery capacity and payback period. The results show that PLTS with a total of 80 solar panels installed with a capacity of each panel 405 Watt peak, then obtained a power capacity of 32.4 kilo Watt peak which is divided into 5 arrays, with a solar charger controller and inverter using a 10kW capacity of 5 units, 80 batteries with a capacity of 400Ah. So that PLTS is able to contribute 39.3% of the total power needed by PT East Colony (electric power from PLN is 60.7%). This hybrid payback period will return after 8 years and 7 months.
