Analisis Teknik Serta Kelayakan Ekonomi Pada Perancangan Pembangkit Listrik Tenaga Surya Sistem Hybrid

Abstract

National electrical energy needs are increasing every year. This is accompanied by an increasingly massive use of fossil energy as a power plant. The government is targeting a share of new and renewable energy (EBT) of at least 23% by 2025. As a tropical country, Indonesia has a large potential for new and renewable energy, which mostly consists of solar energy with an average daily radiation of 4.8 kWh/m2/day. The design of a solar power plant (PLTS) at SMA Negeri 3 Surakarta is an effort to utilize NRE and can be used as a model for environmentally friendly schools for similar public institutions and the general public. This PLTS uses a hybrid system with a generating capacity of 1230 Wp, SCC 60A, 24 V 200 Ah battery and a 2400 W hybrid inverter. Using analysis methods with PVSyst and RetScreen simulations, this PLTS generates electricity of 1,653.2 kWh/year. With an initial investment of IDR 25,186,000, the net present value is IDR 1,210,272 and the payback period is 24 years.
